Doorway in the wall made of tongue-and-groove slabs. Doorway in a partition PGP: ways to make an opening in a partition from gypsum boards

You are doing a major renovation of your apartment with redevelopment or have bought a new building with an open plan, you will definitely be faced with the task of installing several partitions. If you have the opportunity to hire workers, this article will help you control them; if you do the repairs yourself, in the article I will show you step by step how to install a gypsum tongue-and-groove slab (GGP) or a tongue-and-groove partition with your own.

Two methods of installing the PGP partition

It is clear that any interior partition does not hang in the air, but is adjacent to the floor, walls and ceiling of the room. Installation of a tongue-and-groove slab using technology involves two types of partition installation depending on the connection method:

Material for installation of partitions made of GGP (tongue-and-groove slabs)

For work you will need:

• 667x500x80 mm to calculate 3 slabs per meter: 28 kg/1 slab.
• 667x500x100 mm for the calculation of 3 slabs per meter: 37 kg / 1 slab.
• 900x300x80 mm to calculate 3.7 slabs per meter: 24 kg/1 slab.

Note: If the tongue-and-groove slab is installed in a room with normal humidity, purchase standard plate GGP. For partitions in wet areas, we buy a hydrophobized (moisture resistant) GGP board. The moisture-resistant Knauf board is marked with a green stripe.

What thickness of GGP to choose

Interior partitions made of PGP are made in one layer. Technologically, it is impossible to make a straight PGP partition higher than 3600 mm and wider than 6000 mm. Apartments usually do not have such walls, so there are no restrictions on the use of GGP slabs for apartments.

Installation of a tongue-and-groove slab in an apartment

You need to choose the thickness of the slabs for the partition according to its size. The larger the partition, the thinner the slab. For partitions in a new building, it is better to choose 100 mm GGP slabs. For cladding the walls of a balcony and a partition in a bathroom, 80 mm GGP slabs are sufficient.

Tool for installation of the PGP partition

For work you will need the following tool:

• Saw: for cutting slabs;
• Drill or hammer drill: For fastening slabs and mixing mortar. Mixer attachment for drill;
• Notched spatula width 200 mm;
• Simple spatulas: 100 and 200 mm;
• Horizontal level 500 mm and 1500-2000 mm long.
• Plumb line for marking the partition;
• Rubber hammer for upsetting slabs;
• Clean container for mixing the solution;
• Clean water for solution and washing of instruments. Rags.

Installing a tongue-and-groove slab with your own hands - step by step

• Prepare a place for installing the partition. Remove debris and prime the junction areas of the partition.

• The base of the partition must be horizontally level. If a base slope is visible during measurement, it is leveled cement mortar. After the solution has dried, it is primed.
• Mark the partition along the floor, walls, and ceiling. Use a plumb bob or laser level to mark.
• When the partition is elastically (soundproofingly) connected to the floor, a soundproofing strip is glued to the installation site of the partition using mounting adhesive.

• PGP slabs can be installed either with the groove up or with the groove down. However, for reliable adhesion, installation with the groove facing up is recommended.

• Therefore, the ridge of the slabs of the first row needs to be cut off with a saw. Do not use power tools for cutting; the amount of gypsum dust will be unreasonably large.
• The cut slabs in the partition row should not be narrower than 100 mm. Therefore, before installation, do a dry installation and try the slabs in place. If the last slab in a row is less than 100 mm, trim the first slab in the row.

• Install the first row of slabs with glue. The quality of the entire partition depends on the horizontality and verticality of the first and two subsequent rows, therefore, we actively use the building level to control the installation.

• Starting from the first row, with an elastic connection, place reinforcing corners. The corners are attached to the PGP standard self-tapping screws. To attach the corner to the walls, we use dowels and screws.

• The number of staples on one side of the partition cannot be less than 3. That is, in an apartment with ceilings of 2700, we install brackets after the first, third and fifth rows.
• We look at the photo to see how the mounting adhesive is placed in the groove of the bottom row.
• The slabs are installed with a tenon in a groove with glue. We hammer the slab with a rubber hammer. Remove excess glue squeezed out by the top plate with a spatula.

• We constantly monitor the horizontality of the rows and the verticality of the partition.

Connection of the PGP partition to the ceiling

The connection of the PGP partition to the ceiling requires a separate paragraph.

Connecting the partition to the ceiling

Proper connection of the partition to the ceiling is more difficult than to the wall. The last row of PGP slabs is cut at an angle. The angle should be “facing” you. The distance from the bevel to the ceiling should vary from 10 to 300 mm.

When installing the last row of PGP, the sloping void between the ceiling and the slab is filled with mounting adhesive.

The installation of the tongue-and-groove slab is completed. After installing the partition made of tongue-and-groove slabs, inspect it and check the vertical level of the partition. Use the remaining glue to fill, if any, the voids between the plates. Remove any excess glue squeezed out from the seams.

Next, after the glue has hardened, the joints of the partition with the walls and ceiling are glued with reinforced tape and puttied. The partition itself is finished together with the walls of the room, usually plastered several times. Next, according to the repair plan (paint or glue the wallpaper or something else).

Manufacturers of building materials are constantly using innovative technologies to improve quality and speed up repairs. In addition, it is important to minimize costs and simplify the construction process. To zone the space with the least difficulty, you can use partitions made of tongue-and-groove slabs. They are a good alternative plasterboard walls and allow you to get a smooth and stable structure.

Types of tongue-and-groove slabs and their advantages

The tongue-and-groove slab differs from other similar materials in the presence of tongue-and-groove joints at the ends. This feature makes it possible to connect adjacent elements, ensuring a smooth surface and strength of the partition.

There are two types of tongue-and-groove slabs: gypsum and silicate. Each type has its own advantages and disadvantages, which should be taken into account when constructing walls.

To make gypsum blocks, building gypsum and special plasticizers are used. This material differs favorably from others and allows the production of high-quality partitions from tongue-and-groove slabs. They can be either standard or moisture resistant (green) and suitable for use in rooms with any level of humidity.

The main advantages of gypsum boards are: environmental friendliness, high fire resistance, good sound insulation. In addition, hollow blocks can be used, which will reduce the weight of the structure. Their only drawback is the difficulty in hanging shelves and other additional elements. But solid blocks can withstand almost any load, which distinguishes them even from plasterboard partitions.

The main advantage of any partition made of tongue-and-groove slabs is simplicity finishing. It is not necessary to plaster such a surface; simply prime it. After this, it can be painted or wallpapered.

To make silicate slabs, water is used, quicklime And quartz sand. The resulting material has high strength (compared to gypsum) and moisture resistance. At the same time, they are “not afraid” of fire and absorb sound well.

Partition installation instructions

The process of installing walls can be considered using the example of gypsum blocks. This material is one of the most popular in any repair and is perfect for the construction interior partitions. Installation should be carried out after finishing work on leveling the floor surface. Use the best materials famous manufacturers. For example, Knauf. This will avoid unpleasant surprises and problems.

To install partitions made of tongue-and-groove slabs, you need to purchase a number of components and the necessary tools:

• gypsum boards;
• assembly adhesive;
• putty for gaskets;
• gaskets (suitable from treated felt or cork);
• drill;
• mixer;
• hacksaw;
• level;
• rule;
• rubber hammer;
• roulette;
• marker or pencil;
• ribbon or twine;
• putty knife;
• wedges

Once the issues of purchasing materials have been resolved, you can begin to carry out the main installation points. The installation diagram will look like this:

• marking;
• cleaning all surfaces adjacent to the future partition from dirt;
• gluing the gasket to the installation sites of the slabs (Fügenfüller putty is used);
• installation of the first row of tongue-and-groove slabs;
• laying the second row;
• installation of the last row (the edges of the slabs must be beveled);
• sealing seams;
• finishing.

At first glance, everything is simple: a partition made of tongue-and-groove slabs is assembled like a construction set, and there are no problems. But there are some nuances that need to be taken into account.

Firstly, at least a day before installation, you need to bring the blocks into the room. This is necessary for the material to “get used to”, that is, to accept the desired humidity and temperature. Secondly, laying is done with the groove facing up. The grooves are subsequently filled with putty. Before laying the second row, you need to cut the first slab into two parts. This is necessary to arrange the vertical joints in a checkerboard pattern and give mechanical strength designs. Important: the width of the seams horizontally and vertically must be equal!

After the installation of the partition is completed, the surface of the tongue-and-groove slabs must be primed. This will ensure adhesion of the decorative layer and avoid the occurrence of surface defects. Any type of wallpaper and painting are suitable for decoration. The main thing is to choose the pattern or shade you like and carefully apply it to the partition.

Here are some tips to help you install walls to the highest quality:

1. “Many sources contain information that a slab partition can be installed in one day. It is not right. It’s best to let the first layer “settle” for a day, and then continue working.” Zoya makes repairs with her own hands.
2. “Although they say that work with tongue-and-groove blocks is carried out practically without dirt and dust, this is not entirely true. The process of sawing slabs is quite dusty, so you should be prepared for constant cleaning.” Oleg, a novice repairman.
3. “The material is quite new for our market, but already popular. I liked it not only for the smoothness of the surface, but also for the ease of installation. On finished wall I only hung shelves and a TV, but I didn’t dare to put up cabinets,” Dmitry, renovating his dacha.

At first glance, partitions made from tongue-and-groove blocks are perfect option erection of walls and zoning of space. However, such material must also have its drawbacks. Information on ways to solve problems that arise during installation and operation would be helpful. Share your experience with us!

Hello to all readers and blog visitors.
Just the other day I was considering the topic of partitions from. This became a reason for discussing other modern options, for example, construction partitions made of tongue-and-groove slabs. Moreover, I myself really like this option, and perhaps I will use it in a house that...

Tongue-and-groove slabs are a convenient, practical, economical building material for rapid construction partitions

I want to ask you one question. Tell me, can two people install a partition of 20-30 m2 in one day? They can. If gypsum was used to install partitions tongue-and-groove slabs. Yes, perhaps I even thought about 2 people, and one can handle it. Why so sure? With just my own hands I built the walls of a house from expanded clay blocks, and the tongue-and-groove slab weighs a little more, at least hollow - I already held it in my hands while studying it in a construction hypermarket. But this is not the only issue. With my usual pedantry, I studied the issue regarding these slabs, now I will share it, and you will see for yourself. Looking ahead a little, I will say that despite the apparent simplicity of the masonry (due to the magic grooves), nevertheless, the result will be successful only if they are used correctly.

Construction of interior partitions

The most popular material for the device interior partitions in apartments or residential buildings are: brick, slag concrete, expanded clay concrete, gas silicate blocks, plasterboard, and today the hero of the article is becoming no less popular - plaster tongue-and-groove slabs (GWP). The choice of the most optimal option depends on the specifics of the work. For example, they are often erected where the structural fencing requires special strength and increased sound insulation. But the construction of a brick partition, as well as its subsequent finishing and gating, is very painstaking work. But you really want to make your task easier and choose the best option, especially when you do everything in your own hands. In general, my motto in this regard is “ minimum body movements, with greater efficiency". And for this you need to choose the right material and technology. And tongue-and-groove slabs fit my motto in the best possible way.

Structures made of expanded clay concrete, slag concrete and are inexpensive. And by the way from gas silicate blocks, due to their size, masonry also happens quite quickly, plus they are even lighter than tongue-and-groove slabs (but at the same time less durable). But they however require plastering. And expanded clay and slag concrete are also not ideal in terms of environmental friendliness. In addition, all of the listed options do not have these magical grooves due to which the masonry turns out to be perfectly even. In general, when speed and ease of construction are paramount for us and there is neither the desire nor the means for it, and with the condition that in the future there are no plans to hang very heavy interior elements on the walls (for example, a 100-liter boiler), then it is very good option there will be a tongue-and-groove slab.

Characteristics of tongue-and-groove slabs

So what is tongue-and-groove gypsum board and what is the technology for its production? The PGP is a monolithic block with dimensions of 667 x 500 mm and a thickness of 80/100 mm with ridges and grooves along the joining and supporting surfaces. Its weight may vary from 20 to 37 kg, it depends on the type of product and thickness. The technology for producing GGP is quite simple. A solution of gypsum and water of a certain thickness is poured into a special “gypsum cooker”, where the water gradually evaporates and the solution thickens. Next, the resulting mass is poured into molds and sent to the drying chamber, where the material hardens through the hydration reaction of the gypsum binder.

After which the finished slabs are left to stand for at least another day. The result is an environmentally friendly product that is not hazardous to health. Which is odorless, does not contain any toxic compounds, is characterized by increased vapor permeability and is, as it were, a regulator of the humidity regime in the room, like all products made from pure gypsum.

Gypsum tongue-and-groove boards are fire-resistant. Their soundproofing characteristics meet all GOST standards for interior partitions (41 dBA). Among other things, on the smooth and even surface of walls made of tongue-and-groove slabs, after the joints have been erected and puttyed, you can immediately glue wallpaper, and after complete puttying, paint it.

Manufacturers, price

GGPs are produced by many companies, the leaders of which are considered to be the well-known, good old one, as well as "BelGIPS", "Volma" And Peshelansky gypsum plant. One of the important factors of these slabs, compared to other wall building materials, is their relatively low price - 150-260 rub. a piece. Full-bodied ones are more expensive. In order not to be unfounded, I’ll visit my favorite online right now Leroy Merlin(by the way, there is also a favorite Baucenter, but since it is not in all cities, so I’m citing Leroy), you can see the prices in the screenshot (2019).

The price of tongue-and-groove slabs on the Leroy online storefront

And by the way, they are all quite positive reviews, however, some people complain a little about the geometry (slabs from the Angarsk plant). But here, as elsewhere, it depends on the manufacturer, so pay attention to this when purchasing. But everyone unanimously declares - speed and ease of construction of partitions! What else do you need, strength? They are quite durable, at least stronger than those that are fashionable today gas silicate slabs. But they are inferior to brick, yes. But we know that construction options that are ideal in all respects do not exist in nature, there are only optimal options in relation to a given situation. But now it’s time to discuss the pros and cons of these plates.

Pros and cons of tongue-and-groove slabs

Like any building material, these slabs have their pros and cons, let's see what's more.

Pros:

1. Do not contain toxic substances and components.
2. Not flammable, fireproof.
3. They have increased gas and vapor permeability.
4. Partitions made from these slabs are easy and quick to erect.
5. Easy processing(easily planed, drilled, sawed).
6. Front side does not need additional plastering.
7. After finishing the seams, the surface can be immediately tiled, wallpapered and, in some cases, painted.
8. Small price.

Minuses:

1. Not suitable for load-bearing walls/partitions.
2. Manufacturers suggest using it only in buildings where all shrinkage processes have already completed (in principle, this is also true for other materials).

Have you considered the pros and cons? Draw your own conclusions.

Types of tongue-and-groove slabs

On Russian markets There are two main types of GLP: standard and moisture resistant(hydrophobized), which include special additives that reduce moisture absorption (not higher than 5%). The former are used in rooms with a normal and dry climate (no higher than 60% humidity), the latter are preferably in toilets, bathrooms and other “wet” rooms where the humidity exceeds 60%.

Note: in rooms with high humidity, manufacturers recommend using moisture-resistant tongue-and-groove boards. Finished partitions made of PGP are lined ceramic tiles, and apply waterproofing to the area of ​​foreseeable exposure to moisture.

It is worth noting here that some manufacturers paint moisture-resistant boards green during the manufacturing process, while others apply markings confirming this. But one way or another, there is an easy way to find out which slab in front of you is moisture resistant or not. Of course, just spray water on it. If drops roll off the surface (display of water-repellent properties) and are not absorbed, this is a water-repellent slab.

Among other things, both standard and moisture-resistant GGP can be full and hollow. The latter are practically in no way inferior to the full-bodied ones in terms of strength, but they are 25% lighter, and in addition, they are lower in price. For example, the mass of a solid block from Volma, 667 x 500 x 80 mm, weighs 26-28 kg, while the mass of an identical but hollow block is 20-22 kg. Or mass Peshelanskaya a solid slab of the same dimensions weighs 28-30 kg, and a hollow slab weighs 24-26.

Knowing this feature and using lightweight slabs, you can increase productivity by reducing the labor intensity of work, and at the same time reduce the load on the floor, or save, for example, on transportation by increasing the number of GWP blocks in one machine.

Installation of partitions from KNAUF tongue-and-groove slabs

The entire technology of laying/installing the PGP is presented step by step as follows (taking into account the recommendations of the manufacturers themselves):

Gypsum tongue-and-groove slabs are used not only for the construction of interior partitions, but also For interior decoration external walls. In both cases, work with them begins only after the construction of all enclosing and load-bearing structures of the building, but before laying the finished floor.

IN winter time Installation of slabs can be carried out even in unheated rooms, provided that the temperature is not lower than 5 o C. Please note that the slabs require acclimatization, so they must lie in the room being repaired for at least 4 hours.

The construction of partitions from PGP is somewhat reminiscent of assembling a children's Lego set. Important condition installation means correctly combining each element and strictly observing the vertical and horizontal position of the rows of blocks. Confidence in the strength of the structure is guaranteed by assembly adhesive prepared from mixtures recommended by the manufacturer of the boards.

Note: to attach various kinds of objects to tongue-and-groove partitions, a number of requirements must be met. When hanging suspended shelves, sanitary fixtures and other fixtures (weight load from 30 to 100 kg), special corrosion-resistant anchors are used that pass through the entire thickness of the walls. When hanging pictures, mirrors, small shelves with a weight load of up to 30 kg, you can use ordinary plastic anchor dowels. If necessary, place different engineering communications on partitions made of PGP, or in order to increase sound insulation, it is preferable to erect a double partition. In this case, the first to be erected is the partition to which it will be attached. engineering equipment or soundproofing material.

To improve your understanding of the installation of tongue-and-groove slabs, you can watch this video from the manufacturer himself, everything is very detailed and clear:

Installation errors

If a partition made of these slabs “rattles” or allows sounds to pass through when struck lightly, this indicates that some mistakes were made during their installation. For example, maximum permissible dimensions exceeded partitions. They should be: 4.5 x 6 m for slabs with a thickness of 100 mm and 3.6 x 6 m for slabs with a thickness of 80 mm.

Another one of possible errors – rigid connection of the partition with the adjacent structure(should only be done using mounting adhesive), which is only possible in those rooms where there are no regulatory conditions for sound insulation.

And finally, there may be such an option - the partition is poorly attached when the slabs are elastically connected (through the gasket). The technology for installing tongue-and-groove blocks suggests using, in addition to glue, special staples– 100 x 120 x 20 mm. It is worth noting here that the density of the elastic cork gasket must be at least 250 kg/m3, thickness - 5 mm. Instead of cork, you can use a pad made of bumized felt with a density of at least 300 kg/m 3, also 5 mm thick. And if you did everything strictly according to the instructions, then installation errors are excluded.

Video of installation of partitions from PGP

For many it is easier to see once than to read 10 times. One video is good, but two or three are better in order to better understand the material.

This video shows the process of laying slabs on glue:

And in this video there are details on sawing:

And finally, applying putty on the surface of the slabs:

“I worked in many places, mastered a lot of skills. From construction to programming. And by profession I am an ecologist. A few years ago I took a plot of land and began to actively study the construction business in theory and practice. Now the house is standing, and I write articles :)”

Interior wall partitions, in most cases, are not load-bearing structures in the house. They must have sufficient strength and good sound insulation properties. The design of the partition should easily withstand internal communications and hanging furniture.

In this article we will talk about tongue-and-groove gypsum (plasterboard) slabs (GGP). This material is used to create interior and apartment partitions. With a competent approach to construction, partitions made of tongue-and-groove gypsum boards (GGP) will meet the requirements listed above. But you need to focus on ensuring that the installation of tongue-and-groove slabs is competent!

If you neglect to comply construction technology, then the installation of tongue-and-groove partitions will end in the fact that instead of a durable monolith, the builder will end up with a shaky and uneven wall, ready to collapse at any moment.

Kruchenkov User FORUMHOUSE, Moscow.

I have a bathroom partition at home made of tongue-and-groove slabs. Apparently, when a hole was made in it for sewer pipe, Something went wrong. Now, if you shake this structure by the edge with your hand, you can hear the blocks hitting each other.

You can find a lot of similar examples on FORUMHOUSE. And if the partition was originally folded contrary to existing technology, then the defects can be corrected only by completely destroying the structure.

But don’t be afraid, because the technology for constructing wall partitions from PGP is quite simple. And if you treat it with due attention, the impression of the work done will be very positive.

AlexDo User FORUMHOUSE

I worked at a construction site. The buildings of the old foundation were reconstructed. So, all the partitions were made from gypsum tongue-and-groove slabs, the work was a pleasure. Just right as a partition. Easy and quick to install. The walls are smooth. After puttying, they are ready for painting or wallpaper. The fasteners in the slab hold well. Sound insulation is also normal. But if anything, you can make a lath, lay mineral wool and finish it with clapboard or panels.

A little about the practicality of GPP

Manufacturers of gypsum boards guarantee that this material provides reliable fastening standard elements modern interior. This means that gypsum plasterboard partitions can withstand loads comparable to loads on walls made from other standard materials. Wall cabinets, Appliances, stretch ceiling– all this can be easily mounted on a tongue-and-groove gypsum partition. You can expand the functionality of a wall partition made of PGP by installing metal-plastic elements into its body. water pipes(with a diameter of no more than 16 mm) and electrical wiring elements.

You can also install doors in the tongue-and-groove without extras, install electrical wiring without any problems, and hang shelves and TV more reliably.

Tongue-and-groove slabs - what are they?

Standard PGPs come in two types: solid and hollow. The construction of solid slabs is more durable, but this material is significantly heavier than its hollow counterpart. For this reason it is not recommended
used as part of partitions mounted on the floor with
wooden joists.

Hollow PGPs provide high sound insulation (43 dB) without overloading the floor structure. Some people believe that in internal space hollow slabs All kinds of insect pests can live and multiply intensively. But such an opinion has not yet found serious confirmation.

Conventional (solid and hollow) tongue-and-groove slabs are used to construct partitions or wall cladding in rooms with dry and normal humidity levels. If the partition is planned to be installed in a room with high level humidity, then preference should be given to moisture-resistant slabs that have a peculiar greenish tint. Keep in mind that such PGPs are slightly heavier than regular solid products.

Preparatory work

List of tools for working with tongue-and-groove slabs:

• Marking cord:
• Hacksaw with a wide blade and large teeth;
• Roulette;
• Putty knife;
• Drill with a nozzle for stirring mixtures;
• Bucket;
• Building level and plumb line;
• Rubber mallet;
• Square;
• Screwdriver.

In accordance with the recommendations of the manufacturers, the length of the wall partition made of PGP should not exceed 6 m. The maximum height of the structure is 3.5 m. It is possible to increase these parameters, but the maximum strength of the partition is ensured only if the specified dimensions are observed.

The base for the wall made of tongue-and-groove slabs must be level, stable and completely free of dust. If the floor is concrete and there are differences in it exceeding 3 mm, then before starting installation work it needs to be leveled; create a leveling layer. Suitable for this building mixture based on sand and cement (mortar grade - not lower than M50).

Alignment of the wall from PGP.

The solution is applied to a clean, damp floor. For getting ideal surface you can create some kind of formwork and fill it with mortar clearly at a horizontal level. After complete drying, the base must be coated with a concrete primer.

If it is possible to do without a leveling layer, then the base for the future partition, as well as the junction of the partition with the enclosing walls, are covered with 2 layers of primer.

If the partition is mounted on a wooden floor, then the base must be reinforced with a strong, even beam.

Kirill147 User FORUMHOUSE

According to the technology, gypsum tongue-and-groove panels require a flat base - a screed or a separate non-sagging beam under the partition.

When the base is ready, you can mark the locations of the partitions and doorways. This is done using lacing, a plumb line and a level.

Installation of the PGP can be carried out at temperatures from -10 to +30°C. Construction material Be sure to bring it into the room in advance. This will help him “get used” to the right temperature conditions and will insure the partition from deformation (when the temperature changes, the slabs may slightly change their volume).

Installation of elastic gasket

To ensure that temperature changes and deformation of the load-bearing elements of the building do not lead to the destruction of the partition over time, the structure made of PGP should be isolated from the base and adjacent walls with a special elastic (damper) tape. Damper tape for PGP protects the wall from mechanical damage and increases the soundproofing qualities of the partition. Elastic tape is a special cork backing(at least 75 mm wide), which we will glue to the base and walls in accordance with the markings made. The boards and tape are fixed with the same mounting adhesive.

Consumables intended for installation work ( building mixtures, gaskets, dowels, hangers, etc.), should be selected based on the recommendations of the GGP manufacturer. At sub-zero temperatures, the installation of PGP is carried out using a frost-resistant adhesive gypsum mixture.

Apply a thin layer of glue to the prepared surface using a spatula. The tape is rolled out from above and pressed lightly with your hands. The glue sets within one hour. After this period, you can begin building the partition.

Installation of PGP

The damper gasket under the tongue-and-groove slabs is covered with a layer of mounting adhesive, onto which the lower, first row of the PGP is laid. The plate can be positioned with the groove up or with the groove down - it doesn’t matter. But if the groove is at the bottom, then the ridge will not have to be sawed off to make the slab level. It is allowed to install the top row of slabs vertically (if this becomes necessary due to material savings).

When laying the first row, the vertical groove of the tongue-and-groove slab and the base of the floor are coated with glue. Special attention care should be taken to maintain vertical and horizontal levels. The slabs should be set using a mallet.

The thickness of vertical and horizontal seams should not exceed 2 mm. After installing the next slab in its place, use a spatula to remove excess glue at its joints.

Additional elements for filling gaps between solid slabs, walls and openings are easily cut from PGP using a hacksaw.

The relative displacement of vertical joints in the PGT masonry must be at least 10 cm. This is prerequisite to ensure structural strength.

At the intersection of two partitions made of gypsum tongue-and-groove slabs, as well as in the corners, the slabs are laid in such a way that their joints overlap each other. Tongue-and-groove elements that interfere with proper dressing should be cut off with a hacksaw.

After the partition is ready, it external corners needs to be reinforced with perforated metal profile and putty.

People often ask whether it is necessary to glue tongue-and-groove partitions with serpyanka. Yes, the inner corners are glued with serpyanka and coated with putty.

Fastening the partition to the wall

The strength of the connection of the tongue-and-groove partition to the walls and base is ensured by the installation of additional elements: mounting angles, fittings or hangers. It is more convenient to use mounting angles or hangers. After all, they are attached to the slab using ordinary self-tapping screws, and to the walls using dowels. The slabs of the 1st, 3rd, and 5th rows are attached to the side walls. It is possible more often, but there must be several (at least three) fastenings. A strong base connection is created for every second slab.

During installation, direct hangers can be installed directly into the groove of the slab, having previously cut them to the required dimensions.

Between the top row of masonry and the ceiling of the room you will need a technological gap of at least 1.5 cm. It must be left and foamed polyurethane foam. After drying, excess foam must be cut off and the seam must be puttied. Between the top row and the ceiling, additional fasteners are installed at the same frequency as below.

Creating Doorways

For installing door or window openings, the width of which does not exceed 90 cm, you can make masonry without additional reinforcement. In this case, an auxiliary structure made of wooden beam, which is removed after the slabs of the top row are laid and the mounting adhesive has set.

If the opening width exceeds 90 cm, then a wooden or metal lintel should be installed above it. The ends of the lintel should protrude 50 cm beyond the opening on each side. This will ensure even distribution of the load on the partition.

The door (window) frame is attached to the partition using frame dowels and mounting foam.

Inter-apartment partitions made of PGP

Apartment partitions made of PGP, unlike interior partitions, are made double. A technological gap of 4 cm is left between the plates. First, one partition is erected, then the second. In order to enhance sound insulation, the space between the slabs is filled with soundproofing material, mineral wool, etc.

Installation of communications

The design of partitions made of PGP allows for the installation of hidden electrical wiring. Gypsum boards are strong enough to allow vertical grooves to be made into them and are thick enough to install distribution boxes. Technological cavities inside hollow PGP can be used as horizontal grooves.

If the channel chosen for laying the wire is expanded with a crown with a diameter of 45 mm, then the cable will pass through it without difficulty. The main thing is not to clog the side hole of the slab with glue during installation work.

To make it more convenient to pass the wire through horizontal channels, blind mounting holes can be made in the side surface of the partition.

Some doubt the safety of vertical gating of plaster walls. But, according to manufacturers (and the builders themselves), there is nothing to be afraid of.

There are quite a lot of building materials available for the construction of interior partitions. But not all of them are suitable for use in multi-storey buildings. Partitions should be as light as possible in order to minimize additional load on bearing structures building. Thus, the choice is narrowed down to masonry materials such as tongue-and-groove slabs and blocks.

The construction of partitions inside already finished housing has certain specifics. It will be necessary not only to accurately mark the location for the construction of the additional wall, but also to prepare a foundation for it, create a vibration-damping layer at the junction points, provide for fastening the blocks to the walls, and properly organize doorways or arches. Ideal geometry and impeccable quality The masonry will be provided by craftsmen from the Repair Prestige company. They have to solve the problem of constructing partitions from tongue-and-groove slabs and blocks at almost every facility where redevelopment of premises is planned, and they have mastered the technology to perfection. In favor of concluding an agreement with our company to tight deadlines and excellent quality you can add very affordable prices for this type works

Unlike “flying brigades,” the Repair-Prestige company does not disappear anywhere after the commissioning of the facility. We have been on the market for almost 10 years, and our long-term warranty allows customers not to worry about problems that may arise during the operation of the partitions, which, however, is unlikely.

Blocks or tongue-and-groove slabs?

First of all, it is worth deciding what material to build the partitions from - gypsum blocks or tongue-and-groove slabs. From the point of view of composition, they are identical, but they have different shapes, due to which the technologies for their installation performance characteristics and the cost of partitions vary.

The gypsum block is a regular parallelepiped with smooth edges and right angles. The ideal geometry of products is achieved thanks to a special production technology in which high-temperature treatment is not used. The blocks have high strength characteristics and excellent thermal conductivity.

A tongue-and-groove plate is the same block with a thickness of 8 to 10 cm, but equipped with grooves and ridges for joining between structural elements during installation. The dimensions of the slabs used for the construction of interior partitions are usually 66.7 x 50 cm. Thanks to the tongue-to-groove joining, the partitions are absolutely even; displacement of the plates relative to each other is an extremely rare phenomenon.

A partition made from blocks will be somewhat cheaper than one made from tongue-and-groove slabs, which cost more. And this is only the case when the installation is undertaken by professionals who are able to accurately align the blocks along the planes and fix them without distortions or overruns. glue mixture. Such a wall is also thicker, which means the sound insulation will be higher. The downside is that the partition will be heavier due to the thickness of the blocks (hollow blocks can be used as an alternative). A wall made of tongue-and-groove slabs will cost more, but its construction does not require a perfect eye and high professional skills.

Preparing for the construction of a partition

First of all, you need to use laser level mark the walls and floor, marking the boundaries of the new structure. High-quality installation of partitions is possible only on carefully prepared horizontal surface. Therefore, you should start by cleaning the site where the wall will be erected. Before pouring the area for blocks or slabs, the base is treated with a concrete primer (acrylic, concrete contact or other composition for a similar purpose). It is recommended to apply two layers (the second after the first has dried).

Even with concrete floors their deviation from the horizontal plane is possible. Therefore, the surface is checked by level. Differences of more than 3 mm are leveled with cement mortar. A thin platform can be filled with a self-leveling mixture, installing a kind of formwork and using it for uniform distribution composition of a roller with needles. Significant differences are eliminated using a semi-dry screed. It is prepared by mixing cement 500 and fine sifted sand in a ratio of 1:3, adding water until a wet mass is obtained. The mass is laid out on the prepared base and checked for level. After drying (1-2 days), the finished site is treated with a primer, just like the floor slab.

To compensate for thermal expansion and vibrations, a cork substrate (thickness 4 mm, width 150 mm) is installed on the walls and floor in places of contact with blocks (slabs). This damper tape can be installed with the same adhesive on which the slabs will be mounted.

Laying partitions

The laying of slabs and blocks is carried out staggered, moving away from the coincidence of vertical seams by at least 1/3 of the length of the product. The first row of blocks is placed directly on the prepared site. The slabs are placed with the groove up; before installing the first row, the ridge is sawed off. Using a spatula, glue or mortar is spread onto the tape (for the first row and blocks adjacent to the wall), then onto the block itself. The seating of structural elements is achieved by tapping with a hammer through a block or a special hammer with a rubber pad. The excess that is squeezed out adhesive composition cleaned up.

Every second row and every second slab (block) of the first row is attached respectively to the walls and floor by means of perforated metal corners. Wood screws are used for fastening to blocks and slabs; dowel screws or anchors are used for walls and floors. The gap between the top row and the ceiling is foamed and leveled.
