If there is a need to zone a room, then one of the options for creating a partition is to use tongue-and-groove slabs.

This is a relatively new building material that allows you to simplify the construction of the partition as much as possible, its installation is simple and quick.

The specified building material has the form of monolithic slabs, which have precise geometric parameters; they are connected to each other using a tongue-and-groove lock. For the manufacture of such slabs, building gypsum is used, they can be regular or moisture resistant.

Since building gypsum is used to create such boards, they can “breathe”, do not burn, do not emit harmful substances, and are odorless, therefore they are ideal for the construction of interior partitions and decorative ones.

Standard plate size 667x500x80 mm, they have area 0.333 cm2, weight about 29 kg.

The advantage of this material is that it produces a flat and smooth surface; you just need to seal the seams and you can glue wallpaper, paint or lay tiles.

Installation

Before installing the slab partition, you need to check the condition of the base. It must be strong, horizontal and motionless. If the old screed does not meet these requirements, a new one is made. The installation technology resembles

Differences in the height of the base should not exceed 1 cm; if this is not achieved, then it should be leveled.

To install a tongue-and-groove partition, you need to have the following tools and materials:

• tongue-and-groove slabs;
• adhesive composition;
• gaskets, they can be felt or cork;
• putty;
• construction mixer or drill with a special attachment;
• hacksaw;
• level;
• plumb line;
• rule;
• measuring instruments;
• rubber hammer;
• putty knife;
• wedges

Before starting the installation of slabs, the base must be cleared of debris, dust, after which it is covered with a layer of primer.

Marking the future partition can be done after the primer layer has dried.

Mark the doors, and to facilitate installation work, you can tighten the cord.

Markings are applied to the walls and ceiling, for which a plumb line and level are used.

Now you can prepare the solution, to do this, fill the container with water and gradually add the dry mixture, constantly mix everything well, do this with a mixer or a drill with a special attachment. The composition should sit for a few minutes and you can begin installing the slabs.

You need to prepare the glue in small portions so that you have enough for 30-40 minutes of work.

You can lay the slabs directly on the floor, then you will have a rigid fastening. The glue is carefully applied to horizontal and vertical surfaces, on average to install 1m2 of wall you will need 1.5-2 kg of glue.

When using the second method, the slabs are laid on a special cork pad, which increases the sound insulation of the walls. For this use tape 7.5 cm wide, which is glued along the perimeter of the partition.

The gasket is mounted with glue, its horizontalness is checked and it must be given 20-30 minutes so that it is well fixed.

The slabs can be laid either up or down with the groove, but it is more convenient to place it up, since it is easier to apply glue in the groove than on the ridge.

In this case, on all slabs used for installation of the first row, it is necessary to remove the ridge; do this with a chisel or hacksaw, and then level the plane with a plane.

Laying slabs is carried out similarly to laying brick or cinder block: glue is applied to the base, the slab is installed, pressed down with a rubber hammer and its horizontalness is checked. If leveling is necessary, wedges can be used.

When installing the next rows, glue must be applied to both the horizontal and lateral sides so that the slabs are securely connected on all sides.

The seam thickness is about 2 mm, all excess glue that has protruded beyond the slab is removed using a spatula.

For wiring, grooves are made in such partitions, and to install sockets, holes are drilled with a special attachment mounted on an electric drill.

If it is necessary to install large diameter pipes, then install a double partition.

Soundproofing device

Manufacturers indicate that sound insulation coefficient standard tongue-and-groove slab 80 mm thick, 43 dB, which is a sufficient indicator to create comfortable conditions in the room.

In practice, this figure is often lower, therefore, to increase the sound insulation characteristics of such a structure, it is recommended to carry out additional sound insulation.

For this purpose, materials that have good sound insulation characteristics are used. Special membranes Can be glued directly to the wall surface.

To protect the room as much as possible from noise, such membranes glue on both sides of the wall. This allows you to increase the sound insulation coefficient up to 30 dB.

If you have the opportunity to create wide walls, then create a double partition Insulation is laid from tongue-and-groove blocks and between the walls, usually mineral wool.

This method allows you to obtain high sound insulation characteristics and reliably protect the room from extraneous noise.

Building a strong and reliable gypsum partition with your own hands requires experience in construction work; if you don’t have it, follow the following expert advice:

• during the installation of partitions made of gypsum boards, no need to rush. Some people indicate that a partition from tongue-and-groove slabs can be made in a day. It is better to let the first row harden well, and then move on to installing the next rows;
• Please note that when cutting slabs Quite a lot of dust is generated, so be prepared to have something to clean it with;
• the strength of the material allows you to hang shelves or a TV on such a wall, but they can no longer bear the weight of the cabinet.

Conclusion

If the soundproofing characteristics of the wall are very important to you, then they can be increased by creating double partitions, between which insulation is laid or the wall can be covered with sound-absorbing materials.

Follow the instructions, and you will be able to create an interior partition in your house with your own hands, which will have high strength and soundproofing characteristics. Or perform decorative

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:

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 that 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.

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.

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.

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, 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).

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 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.

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 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 :)”

Installing tongue-and-groove slabs for installing partitions has its advantages. This material has a convenient configuration and relatively low weight, which greatly simplifies installation work. The plates are also equipped with a special lock, which ensures their secure fastening.

Important! The arrangement of interior partitions using tongue-and-groove slabs occurs very quickly (almost in a matter of hours). To achieve such installation speed, you need to have extensive experience and perfect command of the technology.

The cost of erecting walls from tongue-and-groove slabs in the company San Sanych

If you are looking for craftsmen to install walls made of tongue-and-groove blocks, pay attention to our company. We have been working in Moscow for a long time and have received many positive reviews. This happened due to a responsible approach to all operations. We carefully listen to the customer’s wishes and implement them taking into account the requirements of regulatory documentation. Only trusted companies that provide the best quality at a low price deliver building materials directly to the site. The cost of installation work will definitely pleasantly surprise you. Prices primarily depend on the amount of labor and materials used.

Preparatory stage

Preparing the room for installation of tongue-and-groove blocks occurs as follows:

• the floor and walls in the areas where the future partition is adjacent must be perfectly flat. Otherwise, the desired quality cannot be achieved;
• all existing irregularities are eliminated by filling the screed and grinding. It is also mandatory to seal cracks on the base;
• the surface of the walls, ceiling and floor is primed;
• markings are applied that reflect the location of the future wall.

Laying blocks

Before installing the first row of slabs that are intended for this purpose, the legs are cut off. This will ensure they fit snugly to the floor. To fix tongue-and-groove slabs, a special adhesive composition is used. It is applied to all their ends to securely fasten them together. Also, a special lock is used for this, which implies the presence of grooves on the surface of the blocks. After installing the first row, it is secured to the wall and floor using dowels. Then the installation continues according to the same scheme.
