How to attach extensions to an interior door. Door extensions: do-it-yourself installation

Not everyone can imagine what extensions installed on interior doors are. Meanwhile, these elements give the door a finished look. Their installation is not difficult and can be done with your own hands, especially after watching the video detailed explanations and photo.

What are extras

Visually, they look like horizontal and vertical planks with different textures and sizes. They are installed between the door frame and the platbands, either with your own hands or with the help of specialists.

Additional strips have not only a functional value - strengthening the door frame, but also an aesthetic one - they mask defects on slopes. The materials used for their manufacture are:

  • board - most often coniferous;
  • Fibreboard, MDF, chipboard, laminated or veneered.

An industrial additional board is a frame made of wood with thin MDF sheets attached to it, which have honeycombs inside, which makes them lightweight, making installation easier. The covering of the extensions matches the color of the door frame and the door itself.

What types of extensions are there for interior doors?

The most popular planks are available for sale: different sizes- from 7 to 40 cm. All extensions are divided into 2 main types. They are:


Advice: if you need to install extensions on a previously installed interior door they adapt attachment elements that fit closely to the box and those that are slipped under it - underlays.

How to properly install extensions on doors between rooms

Do-it-yourself additional boards are installed not only during installation new door, but also existing on the door. The easiest way to attach the extensions is when installing a new structure installed together with the door frame. They must be placed in the form of the letter “P”. The installation procedure is as follows:

  • Stable stools of equal height are placed in a row and placed on them doorjamb, while the inner side should be on top.
  • They check whether all angles are equal to 90 degrees, for which they measure the diagonals - their sizes must match.
  • Using a milling cutter, select a groove for the extensions, if it is missing. Its depth and width must correspond to the thickness of the additional strip.

  • A frame is mounted along the contour of the frame under the door, but not solid, but in separate strips of plasterboard or plywood sheet. It is enough to put 2 pieces at the top, and 3 on the sides. It is recommended to fasten plywood with nails, and drywall with self-tapping screws.

  • Cut out the top element according to the size of the upper groove, and the side parts of the extension according to the length of the side parts of the door frame.
  • Lubricated assembly adhesive or liquid nails edges of the groove.
  • Insert the extensions and allow time for the glue to harden.

  • The temporary frame is dismantled, then the door frame is installed.
  • Align the box: adjust the width dimensions using spacers, checking the verticality of the side parts with a plumb line. The horizontality of the top is achieved by installing wedges under the side parts of the box.

  • Seal the cracks with foam and apply a layer of plaster flush with the wall.

  • They install the trim and skirting boards - the installation of the door with extensions is done with your own hands.

Attention! If a quarter is not selected on the box to mount the extension into, then you will have to place it directly on the outline of the box. In this case, the additional strip should be secured with glue, applied in portions every 100-150 mm. As the foam dries and expands, empty spaces will be filled.

Installation of standard simple extensions with self-tapping screws

Do-it-yourself installation is performed in several steps:


No matter what complex operations you have to perform when installing the extensions, the result is worth it. Once you do everything yourself, you will be convinced of this.

Addition to the interior door: photo

When installing door frames, you often have to deal with the problem of finishing the uncovered part of the slope. The so-called additional elements that go on sale complete with the item you are purchasing are designed specifically for these purposes. door product. But the installation of these elements, which requires careful adjustment to the size of the open part of the slope, is impossible without understanding how to attach the extension to the frame in compliance with the specified installation density.

Types of door frames

Known examples of door frames that require the use of extensions for their installation are divided into two types:

  • products equipped with a groove for mounting an extension;
  • door frames that do not have such a groove.

In the first case, the additional elements are fixed in the groove of the box with one of their ends, while the other of them remains free. The second option for installing the extension involves fixing it on the door slope without rigidly securing one of the sides.

The additional elements are usually made in the form of strips of laminated MDF, having the appropriate color (preferably matching the color of the trim and door frame). Sometimes (in order to preserve the color scheme of the interior) elements of a different, more suitable color are used as additions. Big choice additional elements, differing not only in color, but also in width, allows them to be used when finishing slopes of any size. The main thing is that the width of the blanks you choose allows you to fill the uncovered part of the slope with a minimum of waste.

Installation of elements with a groove

Let's look at the procedure for attaching the extensions to door frames with a groove on them. The sequence of operations performed in this case may look like this:

  1. First of all, you need to install the door frame in place and secure it properly (you can also hang the door itself, which will not interfere with the placement of the extensions).
  2. After this, you should adjust the length of the extensions by trimming them to the required size.
  3. Then you need to measure the amount of indentation from the wall slope to the edge of the door frame (preferably in several places). If there is a large scatter of measurements, the extensions will have to be trimmed in accordance with the contour of the slope. After this, a special edge tape is glued to their end part, to which the platband must subsequently be attached.
  4. After this, it is necessary to fix the extensions in the grooves of the box; and is inserted first horizontal element, and only then the side (vertical) ones are installed. Please ensure that they are positioned strictly at 90 degrees to the plane of the box.
  5. During the installation process, it is advisable to stick masking tape on each additional element along its entire length at 5-7 points, which will ensure its more reliable fixation in the mounting grooves.
  6. Finally, you can fill the gaps formed between the paneling and the wall with polyurethane foam.
  7. After the foam has hardened, it is necessary to cut off all its excess and proceed to attaching the trim.

Installation of extensions without a groove

In this case, immediately after fixing the door in the opening, you will need to carefully measure the uncovered part of the wall (up to the slope). After trying on the trim elements in place, they need to be trimmed (it is best to do this along their long side), after which you can stick pieces of edge tape to both end parts.

For unplastered slopes, the attachment of the extensions is carried out using a small block, which is attached to the slopes so that one of the sides of the extension can be fixed on it. The beam must be aligned strictly to the level, which ensures the correct orientation in space of the installed elements. The procedure for attaching the top panel is as follows:

  1. First of all, the additional element is attached to the bar.
  2. The resulting gap between the wall and the extension is filled polyurethane foam.
  3. After the foam has dried, its excess is removed using a regular knife, after which the casing is attached.

If the slopes have a smooth and plastered surface, they usually do without an additional bar.

Why use them

We see that the technique of using extensions allows us to abandon the rather tedious procedure of plastering slopes. In addition, with a properly selected and reliable established fee the slope takes on a look that can decorate the interior of any modern room.

Before attaching the extensions to the doors, be sure to ask how you can make them yourself, using MDF panels or laminate blanks for these purposes. Such a solution will significantly simplify the task of closing the so-called “divergent” slopes (located in relation to the box at an angle other than 90 degrees).

Mostly all doors that are manufactured in specialized factories are designed for a certain wall thickness. In many cases it is on the order of 70 or 80 mm. But what about the owners of country or ordinary private houses? Their walls are often much thicker than apartment options.

In this case, you can trim the opening with sheets of plasterboard or do it even simpler - install an extension on interior doors. The method is simple and requires significantly less time and effort to implement. Some home owners plaster openings in places where there is no frame. But, nevertheless, the method of installing add-ons is less labor-intensive and more effective. Therefore, you need to carefully figure out how to attach the extension correctly.

The extensions are two racks located in vertical position, and one horizontal bar. It is located at the top of the opening. Thus, the finished structure increases the size of the box itself. Among the commonly used materials for making structures, the most popular are fiberboard, solid wood and MDF. They are wear-resistant and affordable in their price range.

Measuring and preparatory work

The installation of the extensions is necessary first of all in order to securely fasten the platbands. Correct fixation of the platbands can be carried out if the products are placed with their end faces towards the plane of the wall. It is best to take measurements when the box is assembled and installed. After this, the actual installation of the accessories is carried out.

Initially you should put ruler onto the box platform and keep it strictly perpendicular to the wall. It is necessary to determine the dimensions of the upper and lower parts of the product. At the same time, the width of one extension is different parts may differ, since walls are almost always imperfect. All data should be recorded on paper so as not to confuse the product parameters.

Many experienced professionals use more precise method. All additions are measured using square and straight slats. The first device is installed in the seat, and the second is applied to the plane of the wall. Where the square intersects with the rail there will be a width indicator. The size of each slope must be carefully checked, since an error can be made at any stage.

After these manipulations, they begin to cut the board. This is easy to do using hand saw. Jigsaw and stationary machine also work well, subject to availability.

Installation

Installing extensions on an interior door with your own hands is quite simple. To do this, you need to decide, first of all, on the type of box. They are:

  • with groove;
  • without groove.

The first option is the simplest. It has everything to reliably install the extensions. The versatility of having a groove is that it allows you to adjust the position of the extension. This device also saves a lot of time. After adjusting the bar, you can immediately attach it to the wall.

Self-tapping installation

The first thing you need to do is drill a countersunk screw. As a rule, MDF boards, from which blanks are most often made, are approximately 10 mm thick. This means that the drill must have a maximum diameter of 9 mm. In order to more accurately and reliably attach the extensions to the interior door, the diameters of the drill and the head of the screws must match.

The screws themselves are chosen to be of such length that they literally extend slightly into the canvas of the box. If the products are too long, the wood will crack. A prerequisite is the use of wood drills. They are characterized by the presence of special needle-shaped protrusions. Such products are capable of accurately centering holes.

When the tool is selected, drill a hole for the self-tapping screw. In this case, you need to choose not a perpendicular direction, but set the drill at an angle. This method will allow you to secure additional element to the central part of the door frame.

First screwed on with self-tapping screws vertical racks. After fixing them, proceed to the installation of the horizontal strip.

Installation on studs

Another very effective way Installing a door frame is the method of using nails.

For installation, you will need to drill small holes into which finishing nails will then be driven.

Critically important - drilled holes must be less than the length of the nails!

After this, you need to insert the nails with the sharp side outward, and remove the caps with pliers. Mounting timber is often used for driving nails.

When all fasteners in place, you can install the extensions and carefully nail the product, connecting it to the box.

Installation on foam

Installing additional doors using this principle is several times faster than other methods. The products are installed in place. After this, they need to be wedged from the inside. The surfaces should press against the door frame. The opening can be secured only after thorough cleaning and mandatory wetting of the surface.

Installation of telescopic extensions

This type of product has its own unique advantages.

  • It can be tightly fixed in the overall structure.
  • The surfaces adhere securely to each other.
  • Connecting the components together is quite simple.
  • The extensions with this configuration can move either up or down.
  • It is possible to move them inside and outside the product.
  • The power reserve of the parts is small, but these millimeters allow you to adjust the position of the extensions as accurately as possible and correct mistakes that were made during marking.
  • Special “adjustment” grooves make the design convenient and easy to install.

Comes with box

The method is to assemble the entire structure before attaching it to the wall. Both the box and the extensions are assembled into one whole. Additional elements that widen the opening are attached to the door frame. After this, the finished product is fixed.

The following tips will be useful:

  • Nails are used exclusively to press additional panels to the door frame. They don't keep it from moving.
  • During the process of drilling holes, a crack can be made in the front side products and between slopes. Therefore, all work must be done carefully.

Dobor, or additional board - this is a construction element that is used to close missing cracks and gaps doorways in walls and other cracks made of wood. As a rule, the frame is made from MDF. The color of the accessories is wide in its range of choice, like standard extra, as a rule, they are chosen to match the color door slopes and cashing, so that the room has a certain design. The fastening of the extensions is done very tightly.

Dependency in constant use additions is explained by the fact that current door frames are thinner than modern walls. The usual wall thickness, let us remind you, is 8 cm. This difference was previously eliminated in the following way: the part of the wall that was not covered by the door frame was plastered, finished off, and wallpaper was glued to it. With all of the above, the use of extras is the most cheap way make everything beautiful. What are the real advantages of extras, besides being cheap?

We attach the extension to the door frame, in which there is already a “selected quarter” using the following, different method

1) The door block is placed and mounted directly into the doorway, either with or without a door. If the door frame does not have a groove or a special quarter, then it is necessary to cut them with an electric router.

2) Then, a wooden beam and a pair of smaller beams are screwed directly to door block. We made a groove.

3) Using a tape measure, we take measurements, similar to the above method, in four places. Directly from the location of the extension to the door frame.

4) If the lengths are not the same, or you need to reduce the extensions, then a miter saw will help you with this again. With its help, you will trim the extensions to the desired size on all sides. We remove the cuts using edge tape. This can also be done through a special company.

5) Then, you need to install the extensions directly into the groove we cut. First we do it at the top, then on the sides. The upper and lower ones should be located at a right angle of 90 degrees to each other.

6) Using a measuring level or other homemade level, we check the correctness vertically and horizontally.

7) We fasten the extension using masking tape, he must immobilize the entire structure.

8) Empty spaces that appeared with the installation of extensions must be filled with polyurethane foam.

9) When the foam dries, you need to cut off its protruding edges with a regular knife.

10) We install cashing.

This article discusses everything about door trim elements: their types and sizes, the materials from which they are made and how to install them correctly different types this attribute.

What it is?

Often when installing doors it is clear that the canvas alone is not enough to complete the picture. It is necessary to complete the work so that the opening is completed and looks most aesthetically pleasing. To achieve this goal, additional fees are used entrance doors. Additional elements are a U-shaped structure consisting of three overlays - two vertical and one horizontal. They are necessary to complete the installation of the door frame.

Kinds

When choosing extras for entrance group you need to know that they are divided into three types:

  1. Plain without edge. This is the simplest option. It has the appearance of an untreated straight plank. The cuts are hidden, but if there are changes in humidity, this design will not serve you for long.
  2. Plain with edge. When choosing such extensions, all edges will be covered with an edge that will protect the material from moisture. When using these two types of extensions, the structural elements must be perfectly matched, otherwise part of the covering will have to be cut off.
  3. Telescopic. They are the most convenient and most versatile among all presented. The reason for this is that the “groove + tongue” system is used in manufacturing, which allows the use of panels of absolutely any size.

Materials

These devices are made from materials such as fiberboard or laminated boards, metal and wood. If you select an element to metal door, preference should be given to wooden panels. In combination, this will create a reliable and beautiful design. PVC trims are used only with doors of the same material, otherwise a mismatch of materials will be noticeable in the interior.

Advantages

The additions provide the following benefits for the door leaf:

  • Moisture resistance;
  • Resistant to physical influences;
  • Soundproofing;
  • Thermal insulation;
  • Opportunity self-installation;
  • Fast installation speed;
  • There is no need for putty to fill visible imperfections;
  • Large selection of colors;
  • Attractiveness;
  • Resistance to subsidence of the door frame during operation;
  • Long-term operation.

Dimensions

The dimensions of additional elements depend on the size doorway. The width of simple additional elements can vary from 10 to 20 centimeters. Most often, platbands are available in widths of 10, 12.15 and 20 cm. But options with arbitrary, predetermined and required widths for a specific opening are possible.

Usage telescopic extensions allows you to line an opening in a wall of any width. Although there are standards for the sizes of such extensions (90, 120 and 150 millimeters), thanks to their characteristics, such elements can ennoble even the largest opening.

It is necessary to select the dimensions of elements with particular accuracy. Even an error of a centimeter can ruin all the work you have done. It is better to take elements with a reserve, because in the process of work it is easier to remove the “extra” size than to increase the missing millimeters.

Calculation of the number of elements

There are standards to which door manufacturers make doors. In Europe standard height doors - 210 centimeters, in Russia - two meters. The extensions, accordingly, must be of identical length. And they can have different widths: from 5 to 55 centimeters. Quality wooden elements or MDF elements have a width of 10 millimeters.

It is difficult to select parts for private houses. They were built without taking into account modern standards. This often makes it difficult to choose extensions of the required length and width.

  • During installation, the extension will go a little deeper, and accordingly, its size will decrease;
  • The distance between the edges of the door frame is measured with a tape measure;
  • All measurements are checked in three places: on the left, top and right of the opening;
  • The working value will be the largest.

Here is an example of the calculation. The partition has a width of 240 millimeters, the door frame is 80 millimeters. This means that an additional 160 millimeters is required. A blade 200 millimeters wide will suit you; excess is removed with a saw or jigsaw.

Installation process

Each element has its own installation features. Let's consider the installation of each type of extension:

Installation of conventional extensions

You can immediately notice that cladding begins only after the foam has dried and the door leaf has been completely assembled. It is necessary to prepare the surface for cladding. To do this, you will need to clear the foam from a place about 1-2 centimeters deep behind the door frame.

Next comes the installation process itself. The top additional strip is prepared first. First, it is sawed along the length (if possible, you need to make sure that the product is slightly larger than the opening), then the width. To select the correct width of the workpiece, you need to inside Use a pencil to draw two marks using the wall as a guide. For quality work To cut out the part you will need a jigsaw with a wood saw installed on it. After this, the top element is ready to be installed in place. But for final installation it is necessary to make both side parts. They are adjusted in the same way as the top element.

You should also pay attention to the length of all elements.

There should be no gaps between all three extensions, and the top part should be placed in a horizontal groove.

When all of the above has been done, you begin attaching this structure. To begin, take wooden wedges or thick cardboard and wedge it into the box and opening. This is done in order to get rid of the gap between them.

Next, the evenness of the installation of the extension is checked. In this case, it is necessary to check all the gaps: at the joints of the elements, do not forget to check the bottom of the side parts. If necessary, we correct or wedge it with various inserts.

After this, you need a foam balloon with low pressure, when it hardens, we fill all visible voids with it. We first fix the entire structure point by point with foam, then fill all the voids. If it is necessary to install platbands, you will have to wait for the foam to dry completely.

Installation of telescopic extensions

This type finishing elements must be installed if there are cracks and chips on the walls; protruding wires can also be the cause. Thanks to them, aesthetics and tightness are achieved. Another factor may be size - when the wall thickness is more than 140 millimeters, there is a need for such special panels, with which you will close this gap.

When installing telescopic extensions, you need: an accurate eye, accuracy, attention to detail and slowness. There are three ways to install them:

  • with the top bar located between the side bars;
  • with the top bar located above the side ones, top part“lies” on the sides;
  • with cutting down the joints of the parts at an angle of 45 degrees.

The last method is the most difficult to implement, so if you have the slightest uncertainty, you must either choose another option or contact a specialist.

The installation process of such extensions is similar to the installation of conventional extensions. The production of parts begins only after the box with the already hung door leaf. It is necessary to wait for the foam to dry completely, remove the excess pieces of foam that “stick out” and then begin installing the extensions. Their peculiarity is that the width is adjusted not by cutting the part, but by using slats. The width of the additional panel depends directly on the number of slats.

The first step is to install slats around the entire perimeter of the door jamb. Only after checking the accuracy of the work performed can you install the second row, and, if necessary, the third and fourth. Experienced craftsmen can collect finished design all at once, but it’s not worth the risk during installation. It is much better to do this job slowly and carefully.

It is necessary to carefully adjust the horizontal and vertical elements to get rid of possible gaps. When installing, you also need to pay attention to how tightly the ridges fit into the grooves. In the absence of tightness, additional cracks may appear when the parts are driven together. Because this design It is not heavy in weight and it will not experience frequent mechanical stress, that is, there are two options for fastening structures: finishing nails or liquid nails.

Often you may be faced with a situation where the door jamb is far from perfect and there is a skew. But even in this case, you can mount the extensions correctly and beautifully. If there is a skew, then during installation the top part will deviate from the side parts. If there is a deviation of 5 degrees or more, it is recommended to correct the distortion and only then begin to install the elements. When starting work with a warped jamb, over time you may end up with additional cracks that will ruin the entire interior.
