Installation of Volma tongue-and-groove slabs. How to quickly build a partition? Installation of a tongue-and-groove slab with your own hands - step by step Installation of partitions from tongue-and-groove slabs

Hello to all readers and blog visitors.
Just the other day I was considering the topic of partitions from. This became the reason for discussing other modern options, for example the 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 the quick construction of 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 tongue-and-groove slabs were used for the installation of partitions. 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.

Construction of a partition from PGP

Structures made of expanded clay concrete, slag concrete and are inexpensive. And by the way, due to their size, gas silicate blocks are also laid 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 funds 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 a tongue-and-groove slab would be a very good option .

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.

The tongue-and-groove slabs are dried. They are all so white and slender, I just want to take them to my place, to my house)

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.

Bathroom partitions made of GGP gypsum boards

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, right now I will visit online my favorite Leroy Merlin (by the way, there is also a favorite Baucenter, but since it is not in all cities, so I am bringing Leroy), you can see the prices in the screenshot (2019).

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 the gas silicate slabs that are also fashionable today. 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. Simple processing (easy to plan, drill, saw).
6. The 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

There are two main types of PGP on Russian markets: 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 covered with ceramic tiles, and waterproofing is applied 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 board.

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.

Installation of partitions from hollow tongue-and-groove slabs

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):

Installation of KNAUF gypsum boards

Gypsum tongue-and-groove slabs are used not only for the construction of interior partitions, but also for interior decoration of 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, the 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 rest 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. An important installation condition is to correctly combine each element and strictly observe 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 it is necessary to place various utilities 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 engineering equipment or soundproofing material will be attached.

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 possible error is 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 :)”

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 method of connection:

1. Elastic connection (fastening). Elastic fastening involves installing a layer of soundproofing material between the edges of the partition and the walls, ceiling, and floor. An available soundproofing material is cork. It is important to understand that elastic fastening is done where the customer, that is, you, needs to improve the soundproofing qualities of the partition. There are no other criteria for flexible installation of the PGP. 2. Monolithic connection (fastening). Monolithic fastening involves direct contact of partition slabs with walls, floors, and ceilings through mounting adhesive.

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

For work you will need:

1. Gypsum tongue-and-groove board (GGP). Manufacturers: Knauf, Volma, etc. In the size of the GWP, we are interested in its thickness. Slabs with a thickness of 80 and 100 mm are common. The number of slabs is calculated from the area of ​​future partitions with a 10% margin for undercuts. GWP dimensions:

• 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 installation of a tongue-and-groove slab is carried out in a room with normal humidity, a standard GGP slab is purchased. For partitions in wet rooms, we buy hydrophobized (moisture-resistant) GGP board. The moisture-resistant Knauf board is marked with a green stripe.

2. You will need gypsum mounting adhesive. It is sold in 25 kg bags. For bathrooms, you can use tile adhesive. 3. For elastic fastening of the tongue-and-groove partition to the walls and ceiling of the room, you can buy special brackets. Such staples are marked C2 (for 80 mm PGP) and C3 (for 100 mm PGP). The brackets can be replaced with direct hangers (PP 60/125), used in the installation of plasterboard structures.

4. Only for elastic connection! Soundproofing pad is required. These are strips 100-150 mm wide, preferably made of cork. 5. If the floor is uneven, then you will need a dry cement mixture to level the floor where the partition is installed.

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 the base slope is visible during measurement, it is leveled with 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 with 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).

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 adhere to construction technology, then the installation of tongue-and-groove partitions will end up with the builder getting a shaky and uneven wall, ready to collapse at any moment, instead of a strong monolith.

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 the 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 happens, you can make a sheathing, lay mineral wool and finish it with clapboard or panels.

A little about the practicality of GPP

Manufacturers of gypsum slabs guarantee that this material provides reliable fastening of standard elements of a modern interior. This means that gypsum plasterboard partitions can withstand loads comparable to those on walls made of other standard materials. Wall cabinets, household appliances, suspended ceilings - all this can be mounted without problems on a tongue-and-groove gypsum partition. You can expand the functionality of a wall partition made of PGP by installing metal-plastic water pipes (with a diameter of no more than 16 mm) and electrical wiring elements into its body.

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 all kinds of insect pests can live and multiply intensively in the internal space of hollow slabs. 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 you plan to install the partition in a room with a high level of humidity, then preference should be given to moisture-resistant boards 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;
• Construction 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 is necessary to level it; create a leveling layer. For this purpose, a mortar based on sand and cement is suitable (grade of mortar is not lower than M50).

Alignment of the wall from PGP.

The solution is applied to a clean, damp floor. To obtain an ideal surface, you can create some kind of formwork and fill it with mortar precisely 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 under 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 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 must be brought into the room in advance. This will help it “get used” to the desired temperature regime and 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. The 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 PGP 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 to build 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. Particular attention should be paid to maintaining 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 a prerequisite for ensuring the strength of the structure.

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, its outer corners must be strengthened with a perforated metal profile and puttied.

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 with 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 the construction of door or window openings whose width does not exceed 90 cm, masonry can be made without additional reinforcement. In this case, an auxiliary structure made of wooden beams is mounted above the opening, 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 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.

Tongue-and-groove slabs are rectangular gypsum parallelepipeds designed for constructing internal non-load-bearing partitions in rooms with varying degrees of humidity. There are hollow and solid versions of their execution.

KNAUF tongue-and-groove slabs

One of the most famous manufacturers of gypsum boards is the German concern KNAUF. The brand's products are available in three sizes: 667x500x80, 667x500x100 and 900x300x80.

Material of tongue-and-groove slabs

The basis for the production of KNAUF tongue-and-groove slabs is gypsum binder of two grades: G-4 or G-5. The material does not support combustion and does not contain toxic components, which allows its use in hospitals and kindergartens. It does not conduct electricity and is resistant to sudden changes in temperature. A high degree of vapor permeability is characteristic of all gypsum products. The material is easy to machine and has no specific odor.

Technical description of KNAUF boards

The KNAUF tongue-and-groove plate has the form of a rectangular parallelepiped, the design of which provides for a special high-precision tongue-and-groove connection. The finished product has the following technical characteristics for all sizes:

Installation of partitions using KNAUF slabs

Do-it-yourself partition made of tongue-and-groove slabs. Video instruction

Partitions made from KNAUF tongue-and-groove slabs are constructed using the designer method, by precisely connecting a groove on the supporting side and a tongue on the joining side, with gluing of the joining surfaces. The adhesive mixture can be used as glue for gluing drywall " Pearlfix", produced by the KNAUF concern. Installation of tongue-and-groove slabs is carried out with precise adherence to rows in vertical as well as horizontal planes.

Work on the construction of partitions should be carried out after the completion of the production of load-bearing elements of the room, but before laying the finishing floors. This period coincides with finishing work indoors, mainly during the cold season. Temperature indoors should not be below +5 °C. Humidity should correspond to dry or normal conditions. Before use, the slabs must undergo acclimatization, that is, adapt to indoor conditions. To do this, they must lie inside for at least 4 hours.

The permissible length of the partition is 6 m, and the height is 3.6 m. If it is necessary to erect a longer or higher partition, it is made up of separate fragments, each of which has a separate attachment to the supporting structures using a special frame.

Volma tongue-and-groove slabs (solid)

Volma solid slabs have the shape of rectangular parallelepipeds with a tongue-and-groove system, manufactured using injection molding technology. The main purpose is the construction of internal partitions in rooms with three types of humidity according to SNiP II-3-79. Moisture-resistant boards contain hydrophobic additives and special plasticizers. The moisture-resistant version has a characteristic green color.

The material of the stove does not support combustion and does not contain substances harmful to the human body. They have high sound insulation and do not have a specific odor.

Technical characteristics of Volma slabs

The surface of the slab and the geometric accuracy of the design eliminate plastering work when finishing the room. The solid slab is produced in one standard size - 667x500x80. The weight of one plate is 28 kg.

Volma tongue-and-groove slabs (hollow)

For the construction of partitions that require reducing the load on the base of the floor, Volma hollow plasterboards are provided. Their main application is the installation of interior structures in modern panel houses. This is due to the maximum load that the floor slabs can withstand. Like their solid counterparts, the slabs can be standard and moisture-resistant. The standard size remains the same: 667X500X80 mm. Often a hollow slab is used for cladding the outside of a room. The weight of a standard hollow-core slab is 20 kg, and that of a moisture-resistant slab is 22 kg. The material properties of hollow slabs are similar to their solid counterparts.

Installation of partitions from Volma slabs

Installation of a partition made of Volma tongue-and-groove slabs is carried out by precise alignment of grooves and ridges on parallelepipeds, followed by gluing them. Any adhesive for gluing drywall, including that recommended by the manufacturer, can be used as an adhesive mixture for Volma tongue-and-groove slabs. Volma-montage" Installation of the partition structure is carried out in the following order:

Electrical installation in tongue-and-groove slabs

Electrical wiring in tongue-and-groove slabs is carried out by laying wires in pre-made grooves. The depth of laying the grooves has a limitation: it should not exceed 40 mm for a slab thickness of 80 mm, and 50 mm for a slab width of 100 mm. The wires are secured using alabaster or drywall glue. The landing sockets for undercutters should also not exceed the specified depth. Their arrangement is possible in a mirror image on both sides of the partition into a through hole. But in this way the noise-absorbing properties of the structure are lost. For additional insulation of electrical wiring in tongue-and-groove slabs, corrugated tubes are used.

Finishing walls from tongue-and-groove slabs

Like any other building surface, partitions made from tongue-and-groove slabs require all types of construction and finishing work. The advantage of such a partition is the absence of additional putty manipulations preceding decorative work. The finishing of a tongue-and-groove partition includes: painting the surface, laying ceramic tiles and natural stone, and wallpapering.

Laying ceramic tiles on tongue-and-groove walls

The process of laying ceramic tiles on plasterboard is similar to gluing tiles to drywall:

Due to the moisture-absorbing properties of gypsum, the finished surface should not be disturbed for three days.

Wallpapering walls made of tongue-and-groove slabs

Before gluing the wallpaper to the tongue-and-groove partition, you should make small finishing Painting works. This could be the application of a thin layer of ready-made plaster, for example, “ Rotband" Or covering the surface with a layer of finishing fine-grained putty. Before applying the putty, the surface is treated with a deep penetration primer. After the putty has dried, the surface is ready for wallpapering. It is not necessary to treat the base with soil. Gluing wallpaper to partitions made of tongue-and-groove slabs is carried out according to the standard procedure, with glue applied both to the wallpaper and to the base of the surface being glued.

Painting walls made of tongue-and-groove slabs

The tongue-and-groove slab is also painted after finishing the surface. fine-grained putty. After the finishing layer has dried, it is carefully rubbed with a fine sanding mesh under the light of a construction lamp. This is necessary to avoid irregularities and roughness invisible to the eye. The surface to be painted should be treated with a primer and given time to dry. After this, you can apply one or more layers of paint as needed.

Before any type of finishing of the tongue-and-groove partition, it must be thoroughly cleaned and treated with a primer.

Partitions made from PGP are used for redevelopment of premises or delimitation of apartments in new buildings. They are distinguished by their smooth surface, ease of installation and budget cost. The blocks are connected using a tongue-and-groove system; the seams on the finished structure are minimal. This makes it possible not to putty, but to immediately coat the wall with a primer and decorate it.

Tongue-and-groove slabs for partitions are rectangular elements with longitudinal grooves and protrusions (ridges) at the joints, necessary for a strong and seamless bond. Their standard dimensions are 667x500x80 mm, thickness can be 100 mm.

There are tongue-and-groove slabs for large partitions, with a height from floor to ceiling.

Their installation is very fast, but you can’t handle it yourself - due to the large weight of the building elements, a whole team is involved in the installation.

Types of tongue-and-groove blocks for interior partitions, depending on the material of manufacture:

View	Preparation method	Positive traits
Gypsum boards	Made from gypsum with plasticizing additives. Gypsum blocks for partitions are divided into moisture-resistant (green) and those whose moisture permeability is high.	Allowed for installation in children's rooms. Another advantage of gypsum blocks is their ease of processing. Gypsum blocks can be sawn at any angle - gypsum elements can be used to create structures of various shapes and configurations.
Silicate blocks	From quicklime and water with the addition of quartz sand using an autoclave.	They have significant noise insulation qualities. Compared to gypsum, they are resistant to moisture and have greater strength and durability.

PGP partitions can be solid or hollow. The latter weigh less (22 kg compared to 28 for monolithic ones), but cannot withstand hanging massive household items.

Advantages of GGP partitions

The general advantages of partitions made of gypsum or silicone tongue-and-groove boards are:

The use of hollow slabs reduces the load on the supporting base.

The main advantage of such building elements: installation of tongue-and-groove partitions is not difficult. The finished structure does not require any special finishing work. There is no need to plaster the wall, just cover it with a primer and decorate it.

Installation of partitions from PGP

The installation of partition elements made of gypsum or silicate in the apartment begins after the construction of load-bearing parts, but before laying the subfloor and starting painting and plastering work.

Installation of a partition made of standard-sized tongue-and-groove slabs takes only two to three days. This is due to the convenient tongue-and-groove system and the absence of the need for additional reinforcement.

When joining, any deviations along the planes are eliminated, which allows you to quickly assemble an even wall without even a millimeter error.

If you need to hide communications, special grooves are made in solid blocks. In hollow ones, wires and pipes can be laid in the internal cavity. If the construction of partitions from PGP does not involve gating, the double wall method is used. But they “eat up” twice as much space.

Materials and tools

To build a partition from tongue-and-groove slabs you will need the following set of tools:

• roulette;
• electric drill;
• mallet;
• construction level;
• putty knife;
• hand saw;
• ruler, pencil;
• screwdriver;
• mixer for mixing glue.

The materials you will need are the blocks themselves, a cork or felt seal, edge tape, rope, glue, and primer. Fastening elements are also needed: screws, dowel-nails, fixing brackets - straight hangers or corners.

Preparatory work

The construction of a partition created from tongue-and-groove blocks requires certain preparation. First of all, you need to check the compliance of the floor and ceiling horizontal levels, and make sure that the tongue-and-groove slabs are closely adjacent to them: smooth out prominent irregularities, fill cracked areas and depressions with a solution of cement and sand.

The blocks are brought into the room no later than 24 hours before installation so that the material “adapts”, that is, has the necessary humidity and temperature.

To build the wall, gypsum-based acrylic adhesive is used.

But it is very expensive, so many people replace it with regular tile adhesive or a mortar of cement and sand in a 1:3 ratio with the addition of polyvinyl acetate glue. If everything is thoroughly mixed, the result is a fairly plastic and finely dispersed mixture, which can be easily applied with a spatula. It is easier to make masonry with mortar, since its setting time is longer than that of gypsum glue.

Before constructing interior partitions, all surface areas in contact with them are primed and marked according to the previously created drawing.

Laying tongue-and-groove blocks

It is not difficult to assemble a partition from tongue-and-groove slabs with your own hands. The main thing is not to violate the technology when constructing a bulkhead from PGP.

Installation guide for partitions made of tongue-and-groove slabs - step-by-step instructions:

If the structure of a false wall requires an opening for a door, it is necessary to fix the blocks located on top. When installing one row of blocks over an opening up to 0.8 m wide, it is permissible to install them on a door frame or a non-permanent wooden lintel.

If the width is more than 0.8 m or it is necessary to lay several rows, you will need to install a lintel for tongue-and-groove slabs made of wooden blocks or a metal channel.

It is mounted with glue in specially made cuts approximately 5 cm deep in corner blocks. After the solution has dried, the upper rows of slabs are installed.

After finishing the work, the tongue-and-groove partitions need to be primed. Especially if tongue-and-groove gypsum boards were used. The primer ensures adhesion of the decorative layer and will avoid the appearance of surface defects.

Any type of wallpaper and painting are suitable for finishing. It is better to finish the kitchen and bathroom with tiles or plastic panels. For the living room, children's room, and bedroom, wallpaper or decorative plaster is often chosen.
