Finishing window slopes in different ways. Finishing window slopes - interesting finishing options How window openings are finished

After installing plastic windows, the question always arises about the design of the slopes. After all, they perform not only an aesthetic function, but also provide additional heat, sound and moisture insulation. Experts say that designing slopes is a complex and expensive process. In this regard, many are interested in interesting ways and options for slopes on plastic windows.

There are several technologies for installing slopes on windows or the so-called<окосячки>. This includes plasterboard covering, installation of sandwich panels, plastering and finishing with PVC panels. Let's take a closer look at these types.

It is better to sheathe with plasterboard with increased resistance to moisture - gypsum board. There are two ways to cover window slopes with plasterboard yourself: framed and frameless.

Moisture-resistant drywall.

Frame installation method

At the line where the plasterboard joins, a profile is screwed into the groove using self-tapping screws. The frame is ready, installation can begin. The design of window slopes has such a feature that there is empty space between the gypsum board sheet and the wall, this will worsen the thermal insulation qualities of the opening. Therefore, the space is filled with mineral wool or polyurethane foam.

When using polyurethane foam, you should fill the space carefully, because... When drying, the foam tends to increase in volume and can damage drywall.

At the junction of the plasterboard sheets, a perforated corner is mounted and putty is putty on top of it.

Frameless installation method

Basically, the frameless method is used for covering old plasterboards. Before starting work, the surfaces must be cleaned of finishing materials and primed. The plasterboard is cut and prepared in advance, then glue is applied pointwise to the blanks and they are attached to the guide.

To fix the drywall and distribute the glue evenly, you should press it with a wooden block, this will make the structure even.

For additional fixation, use spacers installed to. Complete fixation of the gypsum solution (Rovband or similar) occurs within an hour. Once the sheathing is complete, they begin to putty and paint; you can also cover it with wallpaper.

This is the most common and quite practical method for do-it-yourself windows. Typically, sandwich panels with a thickness of 10 mm are used. They are distinguished by their budget cost, along with high moisture resistance. The surface can be glossy, matte, or stylized as wood. They have a spongy structure, which provides thermal insulation.

Sandwich panels

Another technology for installing slopes is to install a wooden block and secure it with self-tapping screws.

Advantage this method The problem is that with the help of a wooden lath it is quicker and easier to straighten crooked corners, and the unevenness between the lath and the wall is filled with mounting foam or plaster mortar. This method allows you to quickly install window slopes with curvature walls

Minus visual, then even with a small size bar you will have to use a corner of at least 30mm. In addition, when attaching the rail, the corner breaks off.

Fastening is carried out on polyurethane foam. Sandwich panels are placed tightly on the box from the window and foamed, and the other edge is attached to a wooden sheathing. The outer edges of the sandwich panels are secured with screws. The edges where the screws are screwed in will close.

Treat joints and cracks with sealant.

Plastering window openings

This method is the most labor-intensive and requires extreme accuracy, but the least expensive. Mixtures for plaster are based on gypsum and cement. Before use dilute with water.

Technology of work execution

Before plastering begins, the entire working surface is carefully prepared. If there are strong unevennesses, then the entire wall is knocked down and primed. First they plaster the walls, and only then they start working with. This is a very long process, because one layer must dry before the second can be applied. The gaps are filled with polyurethane foam, this provides additional sound insulation. Each layer of coating - base must be primed. Corners are finished with special plaster corners, which ensure the evenness of the corner.

To avoid cracks in the future where the plastic comes into contact with the plaster, acrylic sealant is applied to the corners of the box joints, which can be easily painted.

How to make slopes on plastic windows

To install you will need:

• Plastic panel, they come in three and six meters;
• Starting profile, the same dimensions as the panel;
• Profile F – shaped, for edging a window opening;
• Mineral wool, for insulation;
• "Liquid nails" with a gun,
• Metal screws for attaching profiles to the frame and window sill.

The work is performed in several stages:

1. All cracks are sealed with white silicone sealant.

Warm slopes on the windows in winter will prevent the formation of condensation and, accordingly, the appearance of harmful fungi.

Installing slopes for plastic windows with your own hands is a sure way to save money. Because sometimes in companies this process is expensive and not every company undertakes to carry it out.

If you take the correct measurements and select all the necessary components, making slopes on the windows with your own hands will not be a difficult task for you.

In the process of replacing old window frames with new modern ones, the walls adjacent to them are deformed and destroyed. In some cases, the sash may not open well and you will have to deliberately destroy the plaster.

In addition to aesthetic decorative functions, properly made slopes perfectly insulate heat, moisture and sounds. Become important part, highlight the window, additionally fill the room with light, and can visually deepen the space.

Design of slopes, depending on their varieties, can be both labor-intensive and simple matter. The material used is heterogeneous. And before you start directly finishing the slopes with your own hands, it won’t hurt to glance at the available photos or personally visit a construction market in order to have an idea of ​​its diversity, characteristics, and usefulness.

Classification of works

Simplicity and complexity final repairs premises depends on many factors. Important ones:

• Internal structure, quality of laid walls;
• How carefully did the installers remove the old one? window profile, removed the window sill and unnecessary elements during the installation of a new one;
• What finishing material is chosen?

Before the actual finishing, additional work is carried out to remove excess polyurethane foam, leveling, priming, and insulation. Sometimes you have to completely demolish old structures so that there is enough space to install new ones so that the window opening can open and close normally.

In progress cosmetic repairs if necessary, do the following:

• Finishing with wood, lining, plywood, veneer or MDF;
• Plastering of openings;
• Covering with sandwich panels;
• Plasterboard finishing;
• Sheathing with plastic clapboard.

Wood finishing

Requires filigree precision in the design process. You will have to involve specialists so as not to spoil the expensive material. In addition, this design requires careful maintenance. A more acceptable option, which you can do yourself, is cladding with veneer boards or MDF.

This type of slopes is performed after the installation of wooden classic windows. To highlight the interior design. You can use this method to decorate a metal-plastic window laminated to look like wood.

Plastering

Traditionally, walls are finished by plastering them. Perhaps this is the most labor-intensive way to design slopes, requiring certain skills in working with various building mixtures. The dirtiest and longest. Can be performed with or without insulation. The plaster is applied sequentially layer by layer as the previous one dries.

You can hardly call him simple. In terms of savings, it all depends on the cost of dry mixtures and all the tools that need to be purchased to perform this kind of painting and plastering work.

We pre-prepare the surface. It must be clean and primed. We widen the corner seams for better adhesion of the mixture to the base. The initial task is to level and plaster the surface. Only then do we move on to the actual finishing of the slopes.

The window is sealed polyurethane foam. Outside, on the street side, it is also carefully trimmed and plastered. Open foam darkens under the influence of direct sunlight, collapses, and crumbles. It is important to carefully finish the external joints to maintain tightness, heat and moisture insulation.

We fill large cracks and cavities with fabric soaked in gypsum mixture. When we insulate along the contour, we leave a gap of up to 30 mm to the side parts. In one go we apply a layer of up to 10 mm. We align not from top to bottom, but vice versa. This way the solution will crumble less. Continue after complete drying.

The upper part of the slope is fixed using a wooden strip secured with nails or the plaster itself. The corners are formed using perforated painting profiles specially designed for this purpose.

In the process of finishing in this way, more time is spent waiting for the applied layer to dry than on preparatory work. In addition, you will have to constantly clean up and wash spilled plaster in a timely manner, as it has a detrimental effect on the floor covering.

DIY plastic slopes

There will be less dirt and dust when using PVC lining or sandwich panels. To do this, we will need liquid nails and guides along which the plastic will be attached. When a window opening is sheathed with PVC lining, a pre-lathing is made, in the cavity of which insulation is placed.

When using sandwich panels, the guides are attached directly to the prepared surface using liquid nails, special guide corners. Their structure makes it possible to avoid insulation. They already have it.

Such finishing will cost no more than plastering. Self-locking corners attached to slats are used for assembly. Sandwich panel sheets and lining strips are cut to the required length, inserted into the profile guides, and the joints are formed with corners.

DIY plasterboard slopes

Essentially, the same plaster is used, only dry. No side effects like pollution. All work goes much faster and more fun. Many people prefer this type of slope.

You can use plasterboard sheathing with or without insulation. Excellent alignment, ease of installation, durability – highlight your preference this species window decoration.

Some difficulties can be caused by using primer and putty to protect the cuts and surface. This processing is mandatory. This is the only way the assembled structure will last a long time and the fragile internal structure will not be damaged.

We give preference to greenish plasterboard (GKLV), which has increased moisture resistance. Or - a regular one, cover it with an additional primer in several layers.

We install slopes with or without batten sheathing - we use an “L”-shaped metal frame.

Drywall can also be placed on a prepared surface using mounting foam or glue. The metal “L” profile is fixed around the perimeter of the window frame. Sheets of drywall are attached to it. This method is used when the installers did a very good job and the window opening is badly damaged.

In other cases, the sheets can be mounted with glue or foam to the primed surface itself. Drywall can either fit close to the frame or slightly extend beyond its contours. All joints are filled with acrylic sealant.

Final work – priming, puttying, painting, decorating in the style of interior design of the room.

detailed instructions

The whole process is divided into main and preparatory and marking stages:

Trim off excess foam with a sharp construction knife. We plaster the joints on the street side and install flashings if necessary.

Remove the protective film from the installed profile. Or we cut it along the contour to 20 mm at the supposed junction of the window and the sheet of drywall. We mark the boundaries of the structure for the correct placement of elements vertically and horizontally.

Prepare and level the surface. We remove excess plaster, paint, and all dirt. Treat with a primer. And also the underside of the drywall (the side that will be adjacent to the wall). We wait for it to dry.

We create support for the entire structure. If necessary, we place slats, bars, pieces of drywall to level the surface so that the sheet overlaps the edges of the foamed frame during installation. Or we plaster the walls. The edges of the sheet should not hang in the air, but should fit tightly!

Preparing the plaster adhesive solution. Apply the mixture along the edges with a spatula to the primed side and to base surface. You can make several strokes in the center. There is no need to coat the entire sheet. It will hold strong anyway.

We assemble and install sequentially glued parts. First the upper slope, then the side slopes. After final assembly and drying, we glue all the cracks with the same mixture.

To decorate the corners, we use perforated painting profiles, which we secure with finishing putty over the joined sheets of plasterboard. We prime, putty, cover the surface decorative paint to match the interior color.

Photos of slopes with your own hands

Owners of apartments or houses who have installed new windows quite rightly want to tidy up the surfaces around them. Very often, this simply needs to be done because when installing new window systems, the old slopes are severely damaged and cannot be “restored”, or they come close to the window sash canopies, and this makes it difficult to open. In addition, the slopes are finished in order to enhance the sound and heat insulation of window openings by covering the mounting foam that fills the gaps between the wall and the window block when installing it. Very often, for this purpose, a layer of insulation is laid between the finishing material and the wall.

Slopes on windows with your own hands can be made neat and functional in several ways and using various finishing, insulating or combined materials that combine both qualities. To figure out which option will be easier to install and more suitable for a particular case, you need to consider the most popular of them.

What materials are most often used for installing slopes?

There are three most commonly used methods giving aesthetically pleasing slopes, each of them is good in its own way and can be used in combination with insulating material. So, PVC panels can be installed on window slopes, plasterboard can be glued or fixed to the sheathing, or the surface can be leveled with a plaster and putty mixture.

Slopes made of PVC panels

For finishing using this technology it is used plastic lining and auxiliary fittings. They help to hide the edges of the panels at the junctions of horizontal and vertical surfaces, as well as at the lines where they join the window frame and at the outer corners of the slopes.

In addition to the usual PVC lining, sandwich panels specially manufactured for this purpose are used for cladding, which consist of layers of plastic and foamed polystyrene. This material will facilitate installation, since it does not have to separately adjust and install insulating material. In addition, this approach also often allows you to do without some elements of fittings.

Like regular lining, sandwich panels are great for decorating slopes around plastic windows, especially since, if desired, you can choose the desired PVC color that will be in full harmony with the shade of the window frame.

It is quite possible to install plastic slopes yourself, without resorting to the help of specialists - you just need to study the installation instructions and scrupulously follow them during work.

Plastered slopes

This finishing method can be called traditional. High-quality surfaces will last a long time without losing their neat appearance. However, it should be noted that without a layer of insulating material, plaster cannot become an effective barrier to the cold coming from the window opening. The disadvantages of this method include the labor intensity and duration of arrangement, since the solution is applied in several layers, each of which must dry well. Besides, plastering work require some experience in their implementation, and without it, it is quite possible to ruin the surface, wasting time and money.

The process of finishing slopes with plaster mixtures is quite “dirty”, and since it takes a lot of time (sometimes it takes from one and a half to two weeks), in a room where work is being carried out, it will be necessary to carry out cleaning daily or not use the room at all.

Plasterboard slopes

Often, apartment and house owners prefer to decorate window slopes with plasterboard. This material is easy to install, it can be used together with insulation, the sheathing is quite durable and perfectly levels surfaces. In essence, it is dry plaster, but its installation is much faster than the “wet” version. This method does not cause large pollution in the room during work and does not require much experience to perform it. It is enough to follow the already tested instructions to carry out the finishing carefully and correctly.

Today, several types of drywall are produced, and one of them (GKLV, greenish in color) can withstand high humidity - it should be given preference for the design of slopes. Difficulties during the installation process can be caused not by the installation of the material itself, but by its subsequent finishing for applying a decorative coating - this is a primer and putty. Without these works, “dry plaster” can quickly become unusable, since it has a rather fragile structural structure and can be used for a long time only when covering the cuts and finishing the surfaces.

The installation process is described in detail in the article on our portal “,” which can be easily accessed by following the link. There, in the publication, questions about varieties and performance qualities this material.

Tools and materials for installing slopes

For work on putting the slopes in order, depending on the chosen option, you will need various materials. The list of tools varies slightly - they will be needed not only for installation work, but also for preparatory activities.

Tools for work

To install any of the selected materials, construction tools are required.

A. If plastering work is ahead, you need to prepare:

• Spatulas for applying and leveling solutions.
• Plaster Trowel or Trowel – These are also used to apply plaster or putty mortar to the wall.
• Corner aligner - it will help you quickly and accurately correct the internal and external corners, which always cause the most difficulty in aligning.
• Grater - used for leveling and smoothing plastered or puttied surfaces.
• Falcon - it is convenient to use for bringing the solution to the surfaces to be finished during work.
• Plaster trowel – this professional tool is designed for applying and leveling mixtures.
• An electric drill with a mixer attachment is required for mixing solutions.
• Mixing container.
• A metal profile or wooden strip is necessary to create guides.

B. To install PVC panels, you need to have on hand:

• Sharp construction knife.
• Angle, ruler and tape measure for measuring and adjusting panel blanks.
• A construction syringe for working with sealant or a gun for polyurethane foam.

IN. Some tools are needed to install any of the materials listed above:

• Wide brush for applying primer.
• A building level that will help control the alignment of surfaces ideally in vertical and horizontal planes.
• Metal scissors for cutting reinforcing corners or profiles.

Separately, it is necessary to say about the tools intended for preliminary preparation of slope surfaces:

A hatchet or a special chisel attachment for a hammer drill - these tools will be required in cases where the slopes are made carelessly or are located in such a way that they do not allow the window sash to be opened completely, and they will simply have to be beaten off.

A construction hairdryer - if you can limit yourself to removing the old paint coating.

A spatula is required if you only need to clean the surface of the slopes from old plaster, paint or wallpaper.

Necessary materials

A. If plastic slopes are chosen for installation, the following materials will need to be purchased:

• Plastic panels (or lining), the number of which is calculated according to the parameters of the slope. The panels will be needed for installation on the sides and ceiling of the window opening, which means that in order to find out the exact amount of material, you need to measure the height, width of the slopes and thickness of the walls. Typically panels are purchased with a 10÷15% reserve.
• Starting plastic rail, U-shaped.

• A rail having an F-shape (F-profile).

• Profiles for internal corners installed at panel joints.

• Thermal insulation material - polystyrene foam or mineral wool required thickness and size. If already insulated sandwich panels are used, then you can do without additional thermal insulation.
• Wooden or plywood slats with a thickness of 100 ÷ 120 mm.
• Self-tapping screws of the required length.
• White silicone for sealing gaps between panels.
• Polyurethane foam - it is better to use “professional” foam in tubes, rather than cheap ones in aerosol cans..
• Staples.
• Primer composition.

To install PVC sandwich panels, you will need the same materials, except for the U-shaped and corner strips. An F-shaped strip may be required to decorate the outer corner, but you can do without it by using a putty mixture to decorate it. Which corner finishing option to choose depends entirely on the preferences of the homeowner.

B. To finish slopes with plaster you will need the following materials:

• Putty-plaster mixture.

• Finishing putty.

• Primer antifungal composition.

• Perforated masking profile for strengthening external corners.

• Finishing decorative material: water-based paint, wallpaper or even ceramic tile- according to the preference of the owners.

Preparation of slope surfaces

After everything you need has been purchased and prepared, you can proceed to preparing surfaces for installing finishing materials. This process can be carried out in different ways.

• If the window is installed in such a way that there is enough space around it on the slopes for installing finishing with insulation, then it is often enough just to remove old paint, whitewash or wallpaper from these surfaces.

Whitewash or wallpaper from the walls around the window can be easily removed if you first soak them by soaking them several times with water.

Oil-based or organic-based paint is usually removed with a spatula by heating the surface with a hair dryer.

Cleaned slopes must be primed to avoid the appearance of mold stains under the finishing, which can not only spoil the walls and finishing, but also introduce an unpleasant odor and a very unhealthy atmosphere into the living quarters. The fact is that the fungus can be dangerous to the health of residents, so this stage of work should not be neglected.

The application of primer is most often carried out in several layers, each time after the previous one has completely dried. Not only smooth surfaces are processed, but also hard-to-reach corners - for this you need to use a narrow brush.

• To another, more difficult option preparation includes the complete dismantling of the plaster layer applied to the slopes.

This method is used in cases where a very small distance is left between the window frame and the slope, which does not allow the window to be fully opened. Another situation where this drastic measure cannot be avoided is the impossibility of installing slope insulation or even ordinary plastic panels.

To quickly remove a layer of plaster, a hammer drill with a special attachment called a chisel-scapula is used. It lifts well all the layers applied to the wall, and they are removed in fairly large pieces.

Next, you need to sweep away dust and particles of wall and plaster from the cleaned slopes - this process is carried out using a soft brush or wide brush. Well, after this the wall must be primed with the same antifungal compound.

Slope finishing

To make it easy to install a particular material on slopes, it is necessary to consider each option step by step.

Finishing work begins after the primer applied to the wall is well absorbed and completely dry.

Finishing slopes with plaster without insulation

The process of plastering surfaces around the window is as follows:

Illustration
	The first step is to install guides made of a metal profile or wooden slats around the window niche. It should be noted that a metal guide is preferable, as it has lower adhesion than wood - it will be easier to remove. The guides are aligned to the building level and secured to the wall using dowels. The profile should protrude beyond the corner of the window opening to the thickness of the future plaster layer.
	Another guide from a perforated corner is placed near the window frame. It is oriented towards the profile installed around the opening, since the sketched plaster will be aligned along the plane specified by these two guides. The corner is installed on gypsum-based putty, as it dries quite quickly.
	The next step is to pour the plaster mixture onto the wall. Sometimes it is replaced with ordinary cement mortar, which is mixed from cement and well-sifted sand, that is, in no case should it be interspersed with small pebbles. The task of this stage is to make the outer corner smooth and create the necessary plaster layer.
	The same work is carried out on the ceiling part of the slope.
	After the mortar is thrown onto the slope, it needs to be leveled using a rule, a trowel or a level lath. This layer is leveled, so to speak, roughly, the main thing is that the solution fills all the voids and the edge of the slope, approximately forming an even angle. Leveling should be carried out after the solution has set. The process is carried out from below, from the window sill. The rule is installed on the guides and carefully rises up, leveling the scattered solution, the excess of which is immediately removed. Having completed this work, the slopes are left to dry completely.
	Next, the external guides are removed from the dried slopes, and perforated painting corners are installed on the formed corners using gypsum putty, which will reliably strengthen the edges of the slopes. Having installed them along the entire height and width of the opening, you need to wait until the gypsum composition dries completely - this process will take about half an hour.
	When the putty dries and the corner is securely attached to the wall and slope, another layer of plaster is applied to their surface, which should be the same height as the installed painting corner. It is leveled in the same way, starting from the window sill, using a rule that goes up to the ceiling plane. WITH outside, the edge of the corner is compared with the wall with a solution that is applied with a spatula. Internal corners are formed with a corner spatula, which grasps two planes and the joint between them at once. The leveled slopes are left until completely dry and then primed.
	The last layer consists of finishing putty, and is applied with a thickness of no more than 1-1.5 mm.
	The work is carried out with a wide spatula, with light pressure on it, movements from the window frame towards the room. If marks from the edges of the tool remain on the surface, they must be carefully smoothed out.
	The last stage is the final smoothing of the surface using grout. The process is carried out in a circular motion counterclockwise. After such sanding, before painting, it is recommended to prime the slopes again. The primer will not allow the paint to be absorbed into the putty, so the painting will be even.

Finishing slopes with plaster with insulation

In this finishing option, some stages are similar to the first method, but it also has its own characteristics, so it is worth considering separately.

Illustration	Brief description of the operation performed
	The insulation is mounted on a primed, flat surface. Therefore, if, after chipping the old plaster, chips and potholes are found, they will need to be leveled with a putty or plaster mixture using a wide spatula. After the repair layer and primer have dried, they proceed to gluing polystyrene foam panels, which should have a thickness of no more than 15 mm.
	The material is fixed to mounting foam, which is best applied directly to the insulation, or to mounting adhesive like “liquid nails.” The part coated with strips of glue is pressed tightly against the slopes. Installation of foam plastic is first carried out on side walls, and then onto the ceiling part of the slopes. If necessary, the joints between the foam sheets are additionally filled with foam.
	If the slopes are wide enough, then the insulating panels are additionally fixed to the wall using “fungi” fasteners. To do this, using a hammer drill, holes are drilled in the wall directly through polystyrene foam, into which dowels called “fungi” are inserted. Then special expansion nails are installed and driven into them. Using this fastening, you need to take into account the thickness of the insulation, since the fungus should be recessed into the wall by 50 ÷ 60 mm, and its cap should be level with the surface of the foam or be slightly recessed into it, by 1 - 1.5 mm.
	Having glued the foam, which will level the surfaces and corners, we proceed to reinforcing its surface - only in this case will the finish last a long time. On external corners corners with reinforcing fiberglass mesh are mounted on glue or gypsum-based putty. The glue is applied with a spatula to the edge of the slope, then the corner is pressed onto it, and the excess that protrudes through the holes adhesive composition is immediately deleted.
	WITH outside the corner is also glued with glue or putty. You can use glue on cement based, but if you need the surface to be treated to dry quickly, it is recommended to use a gypsum composition. The mesh is pressed into the applied composition using a spatula, and its excess is leveled or removed.
	Next, the mesh is attached to all foam surfaces. It can be glued to an already applied thin layer of putty or attached to buttons, and the solution can then be applied on top of the mesh, leveling it. This layer will become a preparatory layer for the finishing putty, which is applied to the dry surface. The final leveling layer and other work are performed in the same way as in the first option.

Installation of plastic slopes

PVC panels can be divided into two types - regular and sandwich panels, which have insulation in their multilayer structure. Their installation is most often identical and is carried out using fittings, however, sandwich panels can sometimes be joined using sealant, and glued to the walls using polyurethane foam or “liquid nails”.

Illustration	Brief description of the operation performed
	Finishing slopes with plastic panels begins with fixing a wooden strip around the perimeter inside the window opening, on the slopes, excluding the window sill. This element will strengthen the corner and allow you to easily install fitting profiles on it. If the window opening is wider than the frames being installed, then a wooden beam can also be fixed between the frame and the slope. It is usually installed during foaming of the gaps between the wall and the frame during the installation of the window system itself. In this case, the thickness of the slats fixed along the outer edge is selected depending on the cross-sectional size of the first beam.
	Next, the installation location of the starting profile is determined. If a wooden beam is installed between the frame and the wall, then the profile is pressed against the frame and secured with a stapler and brackets to the wooden beam. This is the operation shown in the photo.
	If the beam was not installed, then the profile is attached directly to the frame, along a line determined using a building level, resting on an external rail. The profile is fixed on the side and top edges of the frame. At the junction of the walls and ceiling of the slope, an angular profile is installed, in which there are two gaps for installing plastic panels in them. The fixed starting and corner profiles are clearly visible in the photo.
	The next step is to attach an F-shaped profile along the outer side of the slopes, reaching the surface of the wall, which will serve not only as a panel holder, but also as a platband. The profile is fixed to a wooden strip installed along the outer edge of the slopes.
	At the corners, the F-profile is cut at an angle of 45 degrees and connected at a right angle. In order for the cut to be perfect and the profile not to be damaged, it is necessary to use a miter box when cutting blanks.
	Next, measurements are taken from the slopes, and parts of the required size are cut out of plastic panels. After this, they are installed in the grooves of the profile - to do this, they can be bent a little.
	In some cases, after bending the profile shelves, their edges “do not want” to completely return to their original place, and gaps form. To bring them back to their original condition, you can apply in these places silicone sealant, and then temporarily fix the assembly with masking tape, which is glued to the surface of the plastic panel.
	Another option for installing conventional PVC panels on slopes can be a method using insulation, which is laid between the slope wall and the finishing material. Installation is carried out in the same way as described above, but in this case a certain space is left for the insulation. 1 - attaching the starting U-shaped rail to the window frame or wooden beam; 2 - installation of a wooden batten on the outer edge of the slope; 3 - attaching the J-profile to a wooden batten - this profile will serve to secure the platband at the completion of the work; 4 - installation of insulating material between the wall and the PVC panel; 5 - installation of a regular or sandwich panel in the starting profile; 6 - installation of the CL profile, which snaps onto the protruding part of the J profile. Additionally, it can be glued to the wall and panel using white silicone or sealant. It should be noted that if sandwich panels are used in this option, then instead of insulating material, polyurethane foam can be used to fill the cavities between the finishing and the wall.

Video: installation of plastic window slopes

Sandwich panels can be installed on the surface of slopes in another way without the use of fitting profiles, but using polyurethane foam, sealant or liquid nails. The gaps between the planes, in this case, are sealed with white silicone.

Installation of sandwich panels directly on slope walls is quite simple, but an important condition it requires a more or less flat surface, so before installing the finishing material, it needs to be leveled and dried.

• Dimensions are taken from the slopes and sandwich panels are cut along them.

• Then one of the selected adhesives is applied to them, and the panel is pressed against the surface of the slope.

If polyurethane foam is used for installation, then glue it first ceiling panel window opening.

The ceiling plane is sprayed with water from a spray bottle - this will increase the adhesion of the surfaces.

Then the foam is applied along the perimeter of the glued part in a thin strip, since it tends to expand quite strongly, and with a large amount of it, the foam can squeeze the finishing material from the wall.

• Having pressed the material to the surface, you need to hold it for 5 ÷ 7 minutes, and then install supports and leave until it dries completely and the foam expands. The support can be made from a planed board, which is pressed against the panel, which is supported with bars, placing them on the window sill.
• After this, the side panels of the slopes are mounted in the same way.

• Then, if there are unfilled gaps between the slope wall and the finishing, they are additionally foamed. When the foam dries and expands, its protruding excess is cut off with a sharp stationery knife.

• Next, the joints between the wall and the finishing material should be closed with a special profile, which is called a platband. It is made in the form of a corner and can have different widths, which allows them to cover the unsightliness of a joint even of large width. The casing is glued to the “liquid nails” and held in place while they dry using masking tape.
• If for some reason small gaps have formed between the panels, they are carefully filled with white silicone, which after drying will be almost invisible.

It should be noted that there are other ways of performing work on finishing slopes, which are somewhat different from those described above, but the principle of their implementation is unchanged.

— First, you need to decide in advance on the choice of material, whether it will be insulated initially or this process will be carried out during the installation process.

— Secondly, choose the material for insulation and for fixing all the parts.

— Third, decide which installation method will be preferable: with or without the use of fitting profiles.

Having decided on all the criteria, you can take measurements and purchase everything you need for work.

Making slopes on windows yourself is not so difficult if you approach this process with the utmost care, take accurate measurements, and select all the necessary components correctly.

Installation of slopes is the final stage of installing a window system. In order for the windows to be truly insulated according to all the rules, it is necessary to take into account many nuances even during the installation of the frames.

– in the corresponding publication of our portal.

Architects creating their masterpieces great importance were given to windows as the final stage in the formation of an architectural ensemble. Sizes, shapes and functional purpose changed over time and the demands of architectural fashion.

Architecture improved, and along with it, windows became the dominant decorative motif of the wall. Having absorbed the variety of styles inherent in a particular era, the windows acquired a laconic appearance and a classic shape. This element of architecture is decorative in nature and surprises with its functionality.

Plastic windows have been prevailing over their wooden counterparts for a long time. Therefore, finishing the slopes of plastic windows and their installation does not lose its relevance.

Types of materials

More recently, plastering of slopes has been in use. At the same time, the adhesion of plastic and plaster was not very good. Very often the seams cracked, due to temperature changes the entire surface of the cladding cracked, hydro-, heat- and sound insulation was damaged. At the same time, plastering is a complex and lengthy process that requires patience and accuracy.

With the help of modern developments, the inside is presented in several types, which involves choosing based on the positive aspects of the materials.

With all the diversity, it is worth taking a responsible approach to the choice of materials, taking into account all the listed factors, first how trim window slopes inside .

Finishing window openings inside with plastic

Finishing window slopes inside with plastic has numerous advantages. Defining parameters:

• aesthetic appearance;
• Duration of operation provides economic benefits;
• damage-resistant material;
• functionality.

In addition to the main characteristics, it is worth paying attention to the technological qualities of the slopes:

• presence of stiffeners (panelite);
• the content of foam insulation (sandwich panel) ensures greater heat retention in the room;
• preventing condensation formation;
• sealed;
• correct installation hides defects;
• the interior decoration of the windows looks symmetrical and smooth;
• large color palette;
• a lamination procedure is possible to create a textured structure;
• matte and glossy surface;
• dust-repellent surface,
• comfort and ease of care;
• ease of installation of the structure.

High-quality finishing of the internal slopes of plastic windows guarantees durability.

Required tools and materials

Interior finishing of plastic windows requires some preparation in terms of acquiring the necessary materials and tools:

• level;
• drill;
• construction knife;
• calculator (for comfort when making calculations);
• F-profile;
• stapler;
• mineral wool (spray foam, ponoizol);
• silicone (sealant, liquid plastic);
• staples;
• antifungal agent (primer, fungicide);
• small screws (“bugs”);
• plastic;
• choppers and slats (plastic, wood);
• masking tape;
• degreaser (alcohol, acetone).

How to do interior window decoration yourself

In order to finish, it is not necessary to resort to the help of qualified specialists. The easiest way, which is completely doable, is to decorate the windows with plastic with your own hands. It is enough to veneer the window opening step by step.

• carefully cut off any remaining foam that protrudes;
• remove paint and old plaster;
• treat with antifungal agent.

1. Panel cutting:

• take accurate measurements;
• put markings;
• cut at an angle of 45°.

1. Installation:

• secure the cut panels around the entire perimeter of the window opening using small self-tapping screws;
• carefully join at the corners;
• if there is a slight discrepancy, adjust the design;
• maintain a gap of 3 cm between the base of the slope and the plastic structure.

1. Filling voids:

• fill the perimeter between the old and new slopes with installation foam (mineral wool, penoizol);
• should not be filled with foam solid line, but at short intervals.

• F-profile corners cut at an angle of 45°;
• to fix the slats, use choppers made of wood or plastic;
• Attach the profile with grooves to the end part of the plastic panel using masking tape.

1. Finish:

• degrease the facing seams at the joints;
• fill them with sealant.

As a rule, finishing plastic windows inside takes no more than 3-4 hours, even without experience.

Reasons why you need to trim the windows in your home

The completeness and neatness of the window are created by slopes, both inside the room and from the outside, and also carry a number of functional loads:

1. external:
   • protection against destruction of polyurethane foam,
   • prevent moisture from entering,
   • thermal insulation,
   • maintain sound insulation,
   • protection from ultraviolet rays.
   • I ensure reliable adhesion of the window frame to the opening.

1. internal:

• decorative component,
• protection of waterproofing materials,
• eliminates condensation.

If the outside slopes are not finished in time, negative consequences will lead to re-installation of the window unit. These are additional costs of money, time, and effort.

Hello everyone! Today we will discuss a topic that is interesting to everyone, finishing internal slopes with plastic. This is especially interesting for those who have just installed new windows.

After installing windows in my house, I had the same question: “How to finish the internal slopes?” There are many finishing methods.

One of the methods is plastering slopes. But this method has many disadvantages: over time they crack, sometimes freeze, and mold may develop. Also, plastering slopes takes a lot of time and is very dusty.

I didn’t want to finish the slopes with plaster and found another way - finishing with plastic. This method is faster, dust-free and reliable. It also provides us with a choice of colors and patterns that we can match to the design of the room. Plastic is durable, unlike plaster.

For myself, I have definitely found a reliable finishing method - plastic finishing. I want to talk about how to do this correctly and avoid making any mistakes in this article.

Slopes for plastic windows. Choosing a method for finishing window slopes: my practical experience

Today I would like to talk about what methods exist for finishing slopes for plastic windows. I will describe to you the pros and cons of this or that method, I will give you a few important advice, and I’ll also tell you about which window slopes I chose.

Just recently, many of our fellow citizens preferred to decorate plastic windows with plaster slopes the old fashioned way. It has now become quite obvious that this method has a number of serious shortcomings. The plaster mixture does not have a reliable connection with the PVC frame, which ultimately leads to the appearance of gaps between the surfaces of the slope and the frame.

It is important!

Due to the composition of the material used, cracks appear on the surface of the slopes. This is facilitated by seasonal changes in air temperature. At low temperatures, there is a possibility of freezing of the slope due to weak thermal insulation properties plaster, which leads to the formation of condensation and mold.

Another disadvantage of plastering slopes is the long duration of the work performed. After all, the plaster is applied in several layers, and each layer takes up to 5 hours to dry. This method is also characterized by high contamination, high labor intensity and, accordingly, high cost. Conclusion: this method is one of the most undesirable.

Slopes for windows made of panelite - cellular plastic

The disadvantages of this method are that the color of the panel changes over time. This becomes especially noticeable on the front surface of the stiffener. In addition, the maximum width of cellular plastic is 25 centimeters. And, if the depth of the opening to be sealed is more than 25 centimeters, then the panels have to be joined together. And this leads to a clear deterioration in the appearance of the slopes.

Glue slope

This is when thin plastic is glued to the surface of the slope. With all its simplicity this method has serious shortcomings. Namely, unreliability due to thermal expansion or contraction of the material used. And, as a result, the plastic peels off. Moreover, there is the formation of condensation and freezing of slopes, since they are not insulated due to the specifics of this method.

Since this article discusses the finishing of window slopes using all existing methods, it is impossible not to mention this. Thin plastic is glued to a sheet of drywall. The disadvantages are that the adhesive connection is not particularly reliable due to the high labor intensity of the work performed. And the notoriously weak resistance of drywall to dampness and moisture.

Some friends of mine developed cracks on their plasterboard slopes after some time. Now they really regret that they didn’t immediately install plastic slopes. So we will not consider plasterboard slopes due to the high probability of their destruction in the near future.

Plastic slopes made from single-sided sandwich panels and double-sided sandwich panels

The first option will not suit us, since it does not have the necessary rigidity. Wide slopes made of this material can sag, although they look good. The second method is good and in appearance no worse than all-sheet slopes 10 millimeters thick. Possesses good characteristics- reliability, rigidity, easy to wash, color fastness.

Note!

Material made from double-sided sandwich panels can easily be used when installing slopes of plastic windows in panel houses, where the width of the slope is from 12 cm. They are no less successful when carrying out work in brick houses with a slope width of up to 60 cm.

And the last of the methods we are considering is the installation of window slopes made of sheet plastic, having a thickness of 8 to 10 millimeters. A very high-quality slope with a thickness of 10 mm, which has high thermal insulation properties. Insulated with mineral wool. The disadvantages include the high cost of the material compared to all previous methods. Although the price, as I found out, is approximately at the same level as that of double-sided sandwich panels.

I chose for myself the finishing of the slopes from sheet Belgian (the highest quality) plastic 10 mm thick. The fact is that a year ago I had slopes installed for plastic windows made of this very material in the kitchen and living room (with a balcony). And I was very pleased. Therefore, when I now replaced the windows in two bedrooms, I settled on a similar method. Having previously considered everything else. Finishing the slopes with plastic cost me about $190 for two windows. I didn't think it was appropriate to save $40 when there was a noticeable difference in quality.

The price included all the necessary materials and work for installing plastic slopes, namely: removing the old plaster layer; leveling and finishing potholes that appeared after dismantling the old window frame; filling the external assembly seam with plaster, as well as the seam under the window sill and ebb; thermal insulation of plastic slopes with mineral wool and alignment of the window opening; installation of plastic slopes itself; sealing all seams formed at the junctions of plastic materials and slopes with waterproof sealant; Well, and garbage collection, respectively.

And finally, what else I would like to draw your attention to. Very important point is the qualification of the craftsmen whose hands will install slopes on plastic windows. It makes sense to pay a little more here, but in the end you will save on nerves and decent quality.

Talk with by different masters from different companies or private individuals. From a conversation with them, you can already get, if not 100 percent, then a completely adequate idea of ​​their professionalism. True, in this case you should also be more or less savvy, at least within the framework of this article.

Look with your friends at the quality of plastic slopes in their houses and apartments, listen to reviews. One of my friends, for example, had plastic that bent outward and became convex and wavy. The so-called “masters” “thought of” covering construction foam under sheets of plastic slopes during the work. And the plastic itself was cheap and thin.

In general, they damaged the guy’s windows. And he, the modest fellow, didn’t even call them to account. When I saw the “quality” of the slopes of some of my friends, I immediately became concerned that this would not happen to me. He approached the choice of craftsmen very carefully, which saved himself from unnecessary headaches. After all, it is known that it is better to prevent than to treat) As a result, this article appeared, based on personal experience.

And you can judge the quality and aesthetic properties of my plastic slopes from the photographs. I'm happy.

source: The fashion for plastic windows is not decreasing. On the contrary, such designs are gradually gaining more and more popularity. However, such an installation is usually accompanied by the need to make window slopes, without which the windows will be ventilated and the room will not please you with its appearance.

As usual, the owners are faced with the question of choosing materials for slopes. It must be said that the choice ahead is quite limited, since it has already happened natural selection materials most suitable for these purposes. In the article we will list what you will have to choose from, and also talk about positive aspects and disadvantages of these materials.

Contrary to popular belief about the dangers of plastic, we dare to assure you that modern plastic panels designed for internal use, are completely harmless to humans. You use a lot of things made of acrylic, silicone, and leatherette, right?

Helpful advice!

Plastic does not emit absolutely any toxins or fumes around itself, therefore it is also environmentally friendly. And don’t let the fact that it allows air to pass through should bother you. Plastered and painted drywall does not let it through either.

A huge advantage of plastic slopes is their practicality. Plastic does not get dirty, does not lose its color, and caring for it is extremely easy. The work on installing the slopes is completed in record time. Slopes throughout the entire apartment are usually made in 1 day. This is the cleanest method of making slopes of all those listed.

The only “dirty” moment is the filling of wooden blocks inside on the walls from the side of the window or doorway. As a minus, it is worth paying attention to the relatively high cost of such slopes. Consider the cost of the plastic itself, profiles for plastic, wooden beams and hardware.

Finishing slopes of plastic windows

Anyone who has at least once replaced old windows with new ones, or installed them in a new building, knows what slopes are. This is the internal and external part of the window opening, which is damaged when dismantling the old window and requires immediate repair after installing a new one.

You should not leave this stage “for later”: while you are rocking, the polyurethane foam that was used when installing windows under the influence of ultraviolet radiation will become unusable and lose its properties. Moreover, in the solidified state, when heated/cooled, it changes in volume by 5-10% and is quite capable of “crushing” itself.

As a result, a gap forms over time between the frame and the foam, negating all sealing efforts. Secondly, foam is not a waterproofing material, so it will constantly collect moisture, which, when frozen, will destroy the foam itself. In general, the slopes need to be put in order even if the aesthetic side of the matter does not bother you much.

Plastic slopes (PVC slopes)

This is a method that involves quickly transforming unpresentable slopes into ideal ones.
Plastic slopes come in several varieties. These are slopes made of plastic panels, universal plastic slopes and slopes made of sandwich panels.

Plastic panels

Plastic panels are the simplest, cheapest and not the highest quality slopes. These panels are made of lightweight plastic that is hollow inside. This slope is not very strong; they are most often used in production premises and offices.

Universal plastic slopes RTD

Their popularity is growing year by year. What are the advantages of plastic slopes compared to traditional plasterboard slopes?

The fact is that RTD plastic slopes are easy to install, which ensures ease and speed of installation. The slopes are assembled from plastic, like from construction parts, with virtually no dust.

If you decide to replace the windows, but do not plan to do any renovations indoors, then we would recommend you plastic slopes; they will suit you best.

Plastic slopes look modern and stylish. They are best suited to VEKA plastic windows. The joints between slopes and walls will be securely and neatly hidden with a special edging. Plastic slopes are very convenient to use, in particular because if they become dirty, they can be washed with water and soapy water.

RTD slopes:

• Length 6000 mm
• Width 600 mm
• Thickness 10 mm
• Ribs thickness 0.52 mm

Advantages of RTD plastic slopes:

1. The plastic slope panel is made of high quality rigid PVC;
2. does not require varnishing, additional painting or special care;
3. environmentally friendly, non-toxic material ensures the safety of human health and the environment;
4. retains its color under the influence of ultraviolet rays for a long time;
5. goes well with finishing materials such as: PVC corners, F-profile, slope casing + casing cover and other materials for interior finishing of slopes;
6. Ideally matches the color shade with products made from white PVC profiles;
7. allows for convenient and easy installation.

Options for finishing window slopes

A plastic window installed in accordance with all the rules will not be able to fully perform its functions if the finishing of the slopes is done poorly. This is due to the fact that the window opening is the main source of moisture penetration into the room, extraneous sounds and drafts.

It is important!

Some believe that to form slopes it is enough to use only polyurethane foam. But this is far from true. Over time, the foam changes its structure and even loses its original properties.

This finishing method also includes a number of finishing works that need to be done for a more aesthetic appearance.

Main types of slopes:

Slopes can be placed both inside and outside the building. The presence of both is very important to protect the premises from the effects of various factors. Finishing is carried out by plastering, using plasterboard or plastic.

Plastering and finishing with plasterboard is quite labor-intensive and not always effective. To completely complete these works, even a professional will need, in addition to certain experience and knowledge, at least a week. These two methods have a number of significant disadvantages that can affect the qualities required for the entire structure.

Finishing slopes with plastering

The building materials market offers a large number of plasters with thermal insulation, waterproofing, and antimicrobial effects. Despite this, over time, plaster slopes tend to lose color and become covered with cracks. Insufficient thermal insulation capacity contributes to glass fogging. The plastering process itself takes place in several stages. Each layer must not only be applied evenly, but also wait until completely dry.

Finishing slopes with plasterboard

Finishing with plasterboard can increase the level of thermal insulation. To do this, it is necessary to carry out preliminary insulation using special materials, for example, cotton wool. In addition, the surface is repeatedly primed and painted. This may take more than a week.

Finishing slopes with plastic

Currently, specialists in the field of PVC structures use exclusively plastic slopes. This is explained by the advantageous features of the material, which allow achieving maximum thermal insulation, waterproofing, sound insulation, practicality and aesthetic appearance of the room.
Modern plastic finishing of window openings occurs through the installation of sandwich panels.

Plastic slopes as the optimal solution for maintaining heat in a room.

Slopes produced using this technology can indeed be called warm. This is achieved through design features the sandwich panels themselves. They consist of several plastic plates and polystyrene foam, polyurethane or mineral wool.

Note!

Thanks to the inner layer, thermal conductivity indicators are minimal. External plastic panels are responsible for protection from various external factors. They are constantly exposed to temperature changes, climatic precipitation and sunlight.

The joint work of all layers of sandwich panels gives the slopes such advantages as:

1. Beneficial effect on creating an optimal indoor climate
2. Resistance to mechanical and chemical stress
3. Sound and heat insulation
4. Resistance to precipitation and ultraviolet radiation
5. Long service life - more than 35 years
6. Ease of installation
7. Easy care and easy cleaning of surfaces from dirt

You can install sandwich panels in a short period of time by contacting specialists or yourself. To carry out the installation yourself, a small set of tools and the availability of special installation materials are enough. By using plastic as a material for slopes, it is possible not only to avoid up to 40% of heat loss, but also to additionally protect installation seams and prevent the occurrence of condensation.

Types of sandwich panels

Using plastic slopes, you can make the window not only functional, but also aesthetic. There are various color and texture solutions for sandwich panels. They can be made to resemble wood, have a classic white color, matte or glossy. How diverse the choice of models will be depends on the manufacturer.

Depending on the basic requirements, warm slopes with a thickness of 10 to 24 mm can be used. Installation is carried out at right angles or at dawn. For the convenience of subsequent repairs, platbands are installed. They allow you to change the wallpaper at any time and make the joints invisible.

The decision on what method will be used to create warm and functional slopes must be made before the main installation of the window. If the finishing will be done by plastering or using drywall, you need to thoroughly prepare for lengthy construction work and purchase auxiliary materials. Companies that install plastic windows very rarely use these methods.

Therefore, you will need to look for masters yourself. If you have chosen plastic sandwich panels, then their order must be carried out jointly with all PVC construction. In this case, the installation of sandwich panels can be carried out together with the window.

source: How to finish an opening when installing plastic windows According to GOST, it is recommended to blow foam into the slope. It simultaneously serves as both a heat insulator and a fixing factor so that the finishing elements sit firmly. But since the slopes do not always bear a large load, some builders recommend making them from sandwich panels.

What is this? Two layers of plastic, between which foam is already poured. This material is attached to a lathing made of thin strips, reinforced along the perimeter of the inside of the window opening, and the whole thing is lined with an F-profile.

In this case, A. Zemskov categorically does not recommend gluing the corners. The fact is that, in addition to temperature deformations, the doors often hit the slopes when opening. Sooner or later, any glued seam will be destroyed. The F-profile is simply pushed under the sheathing. In those places where the sandwich panel is fastened with screws, cutouts are made on the inside where the teeth are.

For the same reason, there are no breakable sashes the best option If there are any, the slopes will be finished with plaster. There is also a purely technical point: plastic profile very smooth and mortar no matter how you smooth it, there will still be waves visible to the attentive and picky naked eye.

In an original way, Zemskov proposes to solve the problem of the joint of the facing profile. If you look closely, this is where you usually see some kind of discrepancy. To do this, the profile is not cut before installation, but after it! First, you need to cut the internal teeth at an angle of 45 - 50 degrees according to measurements (don’t forget about a margin of 1.5 mm).

Then both profiles are tucked into place up to the junction and aligned. And now is the time, placing a sheet of plastic or other material so as not to cut the wallpaper, carefully cut the joint at an angle of 45 degrees with a saw. It would seem like a clumsy solution, but in practice it turns out just fine.

Helpful advice!

And if someone doesn’t like the joint, then some companies that sell materials for finishing a plastic window from the inside even offer to cover the joints with corner decorative elements. In this case, the joint is not visible at all, so the expansion gap can be of any reasonable size. This will help avoid deformation of the entire structure.

What else would you like to add? The finishing of a plastic window on the inside should ideally be done without polymers at all. The same A. Zemskov mentions the phenomenon of depolymerization of window sill plugs. He says they turn yellow over time. This occurs during photodepolymerization. But it is not customary to somehow mention which harmful substances are released during this process. And among them are such as:

1. Hydrochloric acid
2. Benzene
3. Carbon dioxide

We have already provided an earlier review where we said a little more about this problem. Those who are interested can go back and find out some interesting things about plastic windows that dealers keep silent about. And here we conclude the review and remind you that step-by-step instructions for the installation of slopes have already been provided earlier on this site.

The design of PVC windows after their installation includes finishing of the slopes. After completing this work, the corners are decorated with decorative corners or internal slopes are installed on the windows.

Why do you need window treatments?

The interior decoration of plastic windows has not only a decorative function, but also a protective one. The installation seam must be reliably protected from the influences exerted on it so that the window system as a whole functions correctly: the glass does not fog up or freeze, and condensation does not accumulate on the slopes.

The installation seam on the outside must also be reliably protected from exposure to precipitation, wind and sunlight, under the influence of which the polystyrene foam is destroyed. You can effectively protect it by installing metal slopes and trims on plastic windows for exterior finishing, which will give the window a neat, finished look.

Material used for interior decoration of window openings in a house different types. This could be decorative plaster, do-it-yourself installation of PVC panels or drywall on the slopes of plastic windows. The decoration of internal slopes with decorative looks impressive artificial stone. To understand which of these methods is better, it is worth considering each of them separately.

Decorative plaster

When carrying out renovations in a house, interior decorative plaster is often used as a finishing material for walls. This material will make the slopes on the windows unusual and spectacular.

Decorative plaster is often used for interior decoration of slopes

Part decorative plaster may contain fillers of various fractions and origins - these can be natural fibers wood or stone chips or artificial granules of various sizes. Decorative plaster is used as a finishing layer, creating an unusual textured surface or an intricate pattern, like Venetian plaster.

As a material for interior finishing of slopes, decorative plaster has the following characteristics:

• effectively masks base unevenness;
• it can be applied to any base material: brick, concrete, plasterboard, wood;
• this material does not absorb odors;
• safe, non-flammable and environmentally friendly composite;
• has soundproofing qualities;
• in case of minor defects in the base, preliminary repairs are not required;
• when treated with wax or painting, the plaster layer becomes moisture-repellent;
• has breathability;
• Repairing the plaster layer is very simple, there is no need to remove all the finishing;
  finishing of arched window structures is possible.

Types of decorative plasters

Depending on the type of filler and main substance, decorative plasters are:

• textured plaster has a pronounced pattern that is known in advance;

  Texture plaster creates a pre-known pattern

• structural plaster has a less pronounced relief than textured plaster, but its pattern is unpredictable in advance;

  Structural plaster creates an unknown pattern

• Venetian plaster has many layers, resulting in an intricate pattern and smooth surface.

  Venetian plaster creates a smooth, multi-layered surface

Surface preparation

The durability of the plaster layer depends on a well-prepared surface.. Therefore, finishing window slopes inside with decorative plaster should begin with preparing the base.

• The surface of the slopes is cleaned of construction debris and dusted. If there are cracks, they are embroidered and puttied;

  At the first stage, cracks are sealed and the surface is dust-free

• The surface of the slope is primed, a starting layer of plaster is applied and the surface is leveled. At this stage, metal perforated corners are fixed to the corners of the slopes;

  The prepared surface is primed and leveled

• The plaster layer is rubbed down and allowed to dry. Then they are primed again;

  After leveling the slope, the surface is rubbed and re-primed

• apply a decorative layer.

  On final stage perform decorative finishing of the slope

Drywall slopes

Finishing slopes with plasterboard is quick and does not require special construction skills. Installation is possible using polyurethane foam or putty as an adhesive or on a metal frame. Drywall for windows must be marked GKLV.

Drywall on slopes can be mounted on a metal frame

It is characterized by the following positive qualities:

• environmental friendliness;
• affordable price;
• simple installation;
• decorative effect when finishing with any materials;
• smooth, durable surface;
• durability;
• possibility of designing arched openings.

Preparatory work

Surface preparation consists of the following steps:

• foam removal;

  Removing foam residue

• taking measurements of future products;

  The sides are measured from the outside and inside

• manufacturing of parts;

  Using a stationery knife, cut out sheets according to measurements.

• sealing base defects and leveling the surface;

  Level the surface of the slope

• surface primer.

Using polyurethane foam, you can finish a window opening without having any construction skills. It is important to remember that drywall is a fragile material, so the necessary parts must be cut out of it carefully, without any effort.

To get smooth edges at the cut points, it is necessary to make an incision along the drawn line on a sheet of drywall, applying a ruler, using a sharp construction knife. You need to cut the top paper layer and a little inside. Then you can lightly tap along the cut - the drywall will break itself along the intended line.

Foam mounting

• foam is applied to the part and the wall;

  Apply a layer of foam to the panel

• the fragment is applied briefly and removed until the foam expands again. Then they put it in place;

  The part is applied to the slope for some time

• All fragments are secured in this way and left to dry, securing the structure with masking tape;

  Use masking tape to secure drywall

• after 24 hours the joints are puttied;

  After a day it is necessary to putty the joints

• A decorative corner is attached to the corners.

  The corners are covered with a decorative corner

Finishing slopes with plastic panels

Finishing of window slopes inside can be done using plastic ceiling panels or multi-layer sandwich panels. The installation of this material is so simple that it is possible to finish the inside of plastic windows with your own hands. How to make slopes for plastic windows in a house will be described below.

PVC panels are most often used to finish slopes from the inside.

Sandwich panels are better than ceiling panels due to the presence of a layer of insulation inside. However, ceiling ones also have thermal insulation qualities due to the air chambers between the internal stiffeners.

Installation and repair of slopes inside a building using these finishing materials is possible due to their qualities:

• PVC slopes are durable;
• the use of panels for finishing window slopes gives them an attractive, neat appearance appearance;
• finishing options can be very diverse thanks to a wide range of colors,
• which have external surfaces of panels;
• it is possible to install plastic on arched structures;
• Repairing plastic slopes is not difficult;
• ease of installation - window openings are finished with your own hands, and installation does not take much time;
• PVC is easy to process;
• slopes lined with plastic on the inside are easy to maintain;
• finishing window openings with this material increases the energy efficiency of the window system;
• The interior decoration of windows prevents them from fogging and freezing.

Installation

How to install internal slopes for windows made of PVC panels is shown below.

• remove excess polyurethane foam using a stationery or construction knife;

  To remove residual foam, use a stationery or construction knife

• We fix a wooden block along the perimeter of the window opening near the frame using self-tapping screws;

  Secure a wooden block around the perimeter of the frame

• We attach the starting profile to the block;

  The starting profile is attached to the block

• We install a strip along the outer perimeter of the window;

  The rail is fixed along the outer perimeter of the frame

• It’s better to insert the side elements first;

  Side panels installed first

• then insert the top panel, bend it, foam it a little and fix it in the required position;

  A small layer of foam is blown between the upper slope and the PVC panel

• fix the side parts in the same way;
• After the structure has dried, the corner parts are decorated with decorative elements - corners or trim.

  Corners are covered with platbands

Sandwich panels can be installed in the same way or without a starting profile. In this case, the panel is placed in a groove cut in the polyurethane foam. This installation method is relevant when it is not possible to place the block around the perimeter of the window frame.

Platbands

Platbands or casing for internal slopes for PVC windows can be made from different materials, but its functional purpose is the same - protecting the installation seam from destruction and giving the window opening an aesthetic appearance.

Types of platbands

Platbands differ in appearance and functionality:

Materials for manufacturing

The most common material for making cash is sheet plastic. It is used for the manufacture of budget flat platbands, which can be used for finishing windows indoors and outdoors.

This material is not afraid of temperature changes, exposure to moisture or sunlight. Its surface can be laminated and take on any color or imitate various types of natural wood. Therefore, choosing cash to match the color of the window facade will not be difficult.

Plastic cash can be made to match any façade

For plastic platbands deformation from temperature changes and exposure to moisture is unusual.

Profiled PVC trims have the same properties, but may have a shaped surface. They are also used for interior and exterior window decoration.

MDF trims can also be flat or profiled, but they are used exclusively indoors, since the properties of MDF do not allow them to be used outdoors under the influence of surrounding natural phenomena.

For external use, dense foam casing can be used. This material is easy to process and install. The most intricate and complex shapes can be cut from polystyrene foam. It can be decorated with any finishing materials. It has negligible weight, so it does not put any load on the wall.

For exterior finishing windows can use foam trim

The most expensive window design option is the installation of wooden carved cash. Carving can be done by hand or mechanized way. Handmade is very expensive due to its individuality and exclusivity.

Profiled and shaped platbands made of natural wood, made on a machine, will cost less.

Behind wooden platbands careful care is required, since wood, when used in conditions of exposure to the external environment, has some disadvantages:

• wood can become deformed when absorbing moisture or crack as a result of drying out;
• Such cashing looks harmonious on wooden windows or on timber facades. On modern facades such cashing out will look ridiculous.

Fastening

Most often, when installing platbands on a plastic window, mounting elements are used that are fixed to the frame or wall.

The use of removable trims, which are attached to special latches, allows for quick and high-quality installation.

Modern glazing technologies imply careful attention to every detail, so questions about how window sills and slopes are designed also do not go unnoticed by the craftsman. Proper repair These structural elements of the window will provide it with a longer service life and prevent the risk of cold air entering the home. Let's talk further about how the interior window slopes are finished, and what materials need to be used for this.

The need to finish the slopes inside the window

The relevance of finishing window openings indoors and outside the house with sandwich boards, plaster, etc., as well as front door decorative stone is very high. Internal factors, the action of which can negatively affect the quality of the window itself and its slopes, include:

• increased humidity indoors;
• the appearance of condensation on the window due to a significant difference in temperature outside the window and inside the house.

External factors that have a destructive effect on the window and its slopes include:

• precipitation, wind, sunlight;
• sudden changes temperature regime ambient air;
• mold, mildew, harmful insects.

Proper finishing of windows and doors with decorative stone allows you to raise the level of resistance of the window structure to the influence of the described factors to the highest possible level.

This will ultimately extend the service life of the windows, improve the appearance of window openings in particular, as well as the facade of the house as a whole. You can see a window with high-quality slopes inside the room in the following photo.

Drywall

Most often, the decoration of indoor slopes and entrance doors is done using plasterboard. This is a finishing material with high performance parameters, which allows you to quickly and with a minimum of effort make slopes perfectly smooth and resistant to external influences. Drywall has a light weight

, its installation on vertical surfaces is not particularly difficult. It is beautifully painted in the current color shade. In addition, such materials, when properly treated with antiseptic compounds, can prevent the risk of mold and mildew developing at the joints of slopes and window frames. Window finishing with plasterboard is shown in the following photo.

Material selection

You should not think that you can choose any type of drywall to design slopes in your house. The material should be selected taking into account its operational parameters. And they differ for different types of drywall, which should be taken into account by the master before materials are purchased and window repairs begin.

Types of drywall Absolutely any window is a source of moisture in the form of condensation, which is formed due to the large difference in temperature in the house and outside. As a result, the materials used to repair slopes must certainly be resistant to this factor. This means that you need to select only moisture-resistant plasterboard sheets, on which the presence of condensation will not have a negative impact. Otherwise, the repair will retain its functionality, attractive appearance only a short period of time. In addition, it is worth using to cover the surface of the material, as well as special paint for its finishing.

Measurements

Finishing the slopes of plastic windows in a house should always begin with taking measurements, for which you will need to stock up on a measuring tape. The final results of the master’s work largely depend on the quality of this stage of work. If the slope does not fit as tightly as possible to the window frame, there will be a risk of developing such negative consequences as:

• the appearance of mold and mildew outside and inside the premises;
• the appearance of microcracks through which frosty air will begin to penetrate into the house during the cold season. Gradually, without adequate measures to eliminate the problem, the cracks will grow, and with them the costs of heating the premises;
• reduction in the service life of the window structure, its rapid wear both in quality and aesthetic terms.

Taking measurements

Installation of slopes

Finishing slopes with plasterboard begins with an analysis of the measurements taken. All window parameters are transferred to plasterboard sheets, from which you need to cut pieces that are ideal for the window opening.

Drywall cutting process

Installation of such canvases can be carried out on the lathing, on the profile, or without them. The choice of technology should be determined by the fact in which state the slopes are. Visually evaluate whether they are processed with high quality, as well as what quality the double-glazed window itself has.

Installation of drywall is carried out using a special adhesive composition if the walls are perfectly even. If not, you will need to first bring them to this state.

Next, you need to attach the strip to the window profile or frame, which will securely fix the drywall on the side of the double-glazed window. Install on top of the planks plasterboard panels, carefully treating the resulting voids with sealant. Then the structure will be devoid of cold bridges.

PVC panels

No less popular today is the repair of slopes in a house with PVC panels on the profile and doors with decorative stone, thanks to which the entire structure acquires a seamless appearance. This type of repair, as shown in the photo below, is different for a long time service and retains its properties for a long time.

PVC panels

Plastic panels are selected taking into account the size of the window opening, as well as its technical parameters. Before starting repairs, you will need to prepare the surface of the slopes. Then, PVC parts of the current size are cut out, which will be mounted around the entire perimeter of the window on wooden slats and profiles.

If you want to insulate the house, the space between the wall surface and the panels should be filled with a layer of mineral wool or construction foam. Finishing slopes with PVC panels on a profile is also beneficial due to the fact that PVC materials have a smooth surface and are produced in different color shades, looks harmonious in the interior of a private house. This allows you to save on the final painting of the slopes.

Another attractiveness of this method lies in the fact that all elements of the window structure (window, slope) acquire the same expansion coefficient, which will ensure they fit tightly together and prevent the risk of cracks forming.

Scheme for finishing a slope with PVC panel

Surface preparation

To install plastic slabs on a slope, you need to carefully prepare the surfaces. To do this, I carefully cut off the excess mounting foam using a utility knife, and the surface itself is cleaned of dirt and dust, coated with an antiseptic, and primed. Next, you will need to install a metal frame made of guide profiles.

A hairdryer can help remove paint from walls.

Installation of the guide profile

Measure the profile along the outer edge using a construction tape, and then its outer width and the distance from the top edge of the window structure to the surface of the window sill. Take a U-shaped profile of the current width, cut it into pieces using metal scissors, according to the window measurements. Next, the sections are screwed at intervals of 20 cm using screws along the outer part of the window frame. The top and side profiles are mounted in the same way.

Metal profileInstallation of starting profile

Lathing

To organize the sheathing, you will need wooden slats with a cross-section of 20x40 mm, which are fastened on the far corner of the slope from above and on the sides with dowels in increments of 30 cm. The sheathing must have perfect evenness, for which the thickness of the wooden slats is trimmed with a plane and the work is checked with a building level.

Fastening the sheathing

Panel installation

Finishing with plastic plates can be easily done with your own hands. To do this, cut the material with a jigsaw, then fix it on the upper profile and secure it to the sheathing using self-tapping screws.

The side profile is mounted in the same way as the top bar. And the gaps between the window frame and the wall need to be filled with construction foam, for which the surface is first moistened with water. After this you need to lean plastic panel to the base and fix it to it with metal screws.

Fastening PVC panels

Installation of F profiles

The F profile is cut and inserted along the edges of the panels. In those areas where the corners come into contact with the fasteners, you will need to make a small cut. At the same time, the slopes of the front door should be decorated with decorative stone, which looks very expensive. At the end of the work, you need to fill the joints with sealant. white, carefully filling the gap with the composition, removing excess volume.

These measures will not only make the window even more attractive, but also protect it from mold, mildew, and rapid wear.

Sandwich panels

Repair of window and front door slopes can be done with sandwich slabs, as shown in the following photo. The window sills and windows are decorated with sandwich slabs, and the door slopes are decorated with decorative stone. Sandwich plate long time retain visual appeal and original operational parameters.

Sandwich panels

In accordance with all the rules and regulations, repairs of window structural elements can increase the degree of resistance of windows to the negative effects of negative factors inside and outside the house.

The distance between the wall and the sandwich plate must be filled with construction foam, which will act as additional insulation for the structure.

Installation of such plates is not particularly difficult. The sandwich board is fixed to the base using liquid nails, which will provide the connection with high practicality, density, and durability. Check the angles of the slopes for compliance using a small tool. Installation of sandwich boards must be carried out on wooden blocks

, which will make it possible to give the surface of the slope ideal evenness even if there is a deviation of the slope from the vertical. To ensure a neat appearance for the joints of the plates, they need to be treated with silicone.

Common mistakes

It often happens that the finishing of window slopes inside is carried out in violation of technology, which entails a number of negative consequences. In other words, these structural elements of the window opening acquire low resistance to the effects of negative factors indoors, which entails rapid wear of the slopes. This is why it is so important to determine the most common mistakes, which are allowed by inexperienced builders when finishing window slopes:

• incorrect measurements of the base for installation of sandwich or PVC panels, drywall, etc., which leads to loose fit materials for slopes;
• neglect of antiseptic and sealant increases the risk of mold and mildew developing under sandwich panels, drywall and other finishing materials for decorating slopes;
• using plaster mixtures often inexperienced craftsmen try to correct base defects by applying an excessively thick layer of finishing. And this is unacceptable, since plaster more than 2 cm thick may crack after drying;
• When finishing door slopes with stone, you should not give preference to too cheap material. Decorating even with artificial stone cannot be too cheap, because such savings affect the quality of the finish.

Options for finishing window slopes indoors.

If you also decide to install plastic windows, you will certainly be faced with the need to finish the surface around the perimeter of the opening. The untreated strip will have a width ranging from 5 to 15 cm (this depends on the design of the building). The strip is called a slope, it must be covered. But first you need to familiarize yourself with what is needed for this.

Why trim?

Finishing the window slopes inside is the final stage after installing the windows. This procedure is necessary, because otherwise the opening will look unaesthetic. Old slopes are destroyed after dismantling the wooden frames; they need to be closed, which especially concerns the seam. It is filled with polyurethane foam. This allows you to make the opening more protected from frost and get rid of problems with windows.

If the slopes are finished correctly, they will not be afraid of temperature changes. There will be no excess moisture on their surface, and the heat and sound insulation properties of the opening will increase. However, property owners quite often refuse to finish the slopes, putting this work aside. Many people believe that if you foam a window, nothing will happen to it. However, the waiting period for repairs drags on for a long time.

How to avoid mistakes

Experts say that this approach is not correct. The gaps between the double-glazed windows are sealed with polyurethane foam, which has soundproofing characteristics. The foam is affected Sun rays, which can render it unusable. The foam increases in volume and begins to crush itself. Therefore, after some time a gap appears between the foam layer and the frame.

Why you need to hurry

IN open form construction foam does not perform waterproofing functions. It absorbs moisture, which destroys the material when the temperature drops. Foam, being open for a long time, loses its thermal insulation properties. It begins to degrade by 50% when its humidity increases by just 5%.

Using plaster and paint

The inside of window slopes can be finished using plaster. It has a low cost. Before starting work, the cement-based composition must be diluted. The surface around the glass unit is cleaned, dust and bitumen stains are removed from it. Concrete spills in the corners must be cut down.

To improve the adhesion of masonry and plaster, it is necessary to open the seams by 10 mm. As soon as the surface is plastered, it is necessary to level the slope angles. You can start laying a new layer only after the previous ones have dried, for this reason this method can be called long. The plastering procedure can take up to 3 days. The layer turns out to be quite thick in some cases, this is caused by uneven walls.

When finishing window slopes inside with plaster, you need to apply a small amount of the mixture into the groove. This fragment is left until it dries. Afterwards, the plaster is applied in small quantities and leveled until the sinuses are filled. For one opening, the applied layer should not exceed 7 mm in thickness. It should be leveled, directing movements from bottom to top.

To align the joining lines, you need to use a trowel. When finishing, it is necessary to maintain an angle between the wall and the frame. The angles must be the same. Before plastering, it is necessary to strengthen a wooden strip with a horizontal edge on the entire surface of the slope. It can be reinforced with nails; gypsum plaster is also acceptable.

You can install slats on the sides of the surface. Leveling the mixture is carried out with a wooden stick, which has a rounded handle. One end of the tool must be installed on the box, while the other end must be installed on a wooden strip. You can begin leveling the edges only after the mixture begins to set. Afterwards a covering layer is applied, which must be rubbed down. Once the plaster has dried, the slats must be removed. The remaining sides are treated the same way.

The covering layer should have a thickness of 22 mm along all slopes. When the inside of window slopes is finished with plaster, the windows should not be opened. If the mixture gets into the fittings, it damages them, and as a result the window will not cope well with the tasks assigned to it. An even layer of plaster will allow the window to open and close normally throughout its operation.

Disadvantages of finishing with plaster

Despite the fact that finishing with plaster is quite cheap, some property owners refuse to use it, because this technique has some disadvantages. Among others, we can highlight the fact that the mixture does not connect reliably enough to the plastic frame, which leads to the appearance of gaps between the slope and the surface of the frame.

Seasonal temperature changes and insufficient elasticity of the mixture contribute to the formation of cracks on the surface. Among other things, plaster does not have special heat-insulating properties, which causes the formation of condensation and mold.

Plasterboard finishing

You can finish the inside of the window slopes with plasterboard. This method is traditional; it is preferred due to the moisture resistance of the material. This quality is especially important for windows, because condensation often forms on them. You can also take ordinary drywall, which is treated with a primer applied in several layers. To do this, you should use a moisture-proofing compound. As for moisture-resistant gypsum board, it has high rigidity, increased thermal stability and excellent thermal insulation.

If you finish the inside of window slopes with your own hands using plasterboard, you will get many advantages over finishing with plastic. The advantages are the low cost of materials and the possibility of repairs. The damaged area can be covered with putty and repainted.

Drywall is also good because it is able to maintain optimal humidity in the room. It absorbs the excess, releasing it back when the humidity level drops. But if it exceeds 75%, then the drywall may swell, losing its characteristics. When choosing it, you need to be prepared for negative aspects: the material has low strength, so the slope can be damaged by mechanical stress.

Work methodology

Finishing window slopes inside wooden house can also be done using drywall. It is fixed to a metal or wooden crate. You can use polyurethane foam for this if the putty does not adhere well. As alternative solution glue comes out. After installing the window, excess foam is cut off, old finish is deleted. The surface should be treated with a primer. If there are cracks and potholes, they are leveled with plaster mortar.

In order to prevent the penetration of moisture into the drywall and prevent the occurrence of mold, it is necessary to impregnate the slope with a moisture-resistant composition. Drywall is cut. The sheet must be marked according to the parameters of the window opening. You need to use a special knife for cutting. The slope is assembled from the top panel. The glue is applied to the sheet in a single strip. Its width should be 2 cm. The panel is installed in the starting strip, while the second edge of the sheet is pressed against the wall. Afterwards, you can proceed to the side panels, which are inserted into the grooves.

All joints are treated with neutral sealant. When finishing window slopes with plasterboard inside a room, it is important to prevent premature wear of the corner. For this purpose, painting corners made of aluminum or galvanized steel are used. In those places where the gypsum board enters the profile, you should stick a mesh tape so that cracks do not appear there. Then the surface is prepared for painting; for this, several layers of putty are applied, rubbing the surface well. Drywall can be painted with acrylic or oil paint.

Plastic slopes

The most versatile are plastic slopes. Their designs contain mineral wool, which gives the products hydro- and thermal insulation abilities. Plastic can last more than 20 years. It is rational to install it for the reason that the slopes can be made on the same day that the windows were installed. The work doesn't take that much time.

Plastic openings have high moisture resistance, rigidity and strength. They do not fade, are easy to clean and do not fog up. The material corresponds to the one from which the glass unit is made. Therefore, when temperature changes occur, expansion occurs equally, and excessive stress does not occur in the slopes. Additional painting work is excluded. The openings take on a finished look, so they fit perfectly with other structures in the room.

Sandwich panels

You can also finish the inside of the window slopes with sandwich panels. They are products made from two sheets of plastic, between which extruded or foamed polystyrene is located. The thickness of such panels can vary from 8 to 36 mm. When lining a window opening, it is better to use panels whose thickness is 1 cm.

The base can be plastic or wooden openings, the width of which varies up to 150 cm. The advantages of the panels are that they do not need to be insulated, because the appropriate material is included in the design. But such a finish also has some disadvantages, one of which is that the panel may delaminate when exposed to moisture.

Finishing the inside of window slopes with plastic with your own hands involves carrying out work on installing the products the next day so that the polyurethane foam dries well. For best insulation characteristics, slopes are installed simultaneously with window sills. Sandwich panels can be fixed using one of several methods, but the most common of them is the one described below.

When finishing the window slopes inside with plastic, the ends of the panels are fastened with dowels to the base, after which the craftsmen begin installing fasteners and decorative corners. The seams connecting the panels to the window sill are treated with PVC-based glue. You can use a neutral sealant for this. If we compare it with silicone, then it does not have a sticky consistency, as a result, the seams do not turn yellow when dirty.

Using wall panels

When choosing materials for finishing window slopes inside, you should pay attention to Wall panels, which are not so expensive compared to their sandwich counterpart. Panels are hollow products, inside of which the stiffening ribs are located transversely. The thickness is equal to one centimeter, while the width can vary from 25.39 to 37.5 cm. As for the length, it is equal to 2.7 or 3 m.

Finishing of window slopes inside with plastic is carried out in cases where the depth of the plane does not exceed 25 cm. This is true for the reason that wider openings do not allow the rigidity and strength of the coating to be achieved.
