Laying tongue-and-groove tiles. Do-it-yourself interior walls made of tongue-and-groove slabs. Connecting the partition to the ceiling

Tongue-and-groove slabs- these are rectangular gypsum parallelepipeds intended for the installation of internal 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. He doesn't spend electricity and resistant to sudden changes temperature regime. A high degree of vapor permeability is characteristic of all gypsum products. The material lends itself perfectly machining and has no specific odor.

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 completion of production load-bearing elements premises, but before laying the finished 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 load-bearing 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 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 option 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 exclude plastering work when decorating a 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 maximum load which 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 slab is 20 kg, moisture resistant - 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. As glue mixture for Volma tongue-and-groove slabs, any adhesive for gluing drywall is used, including that recommended by the manufacturer “ 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 of tongue-and-groove slabs provide for all types of construction finishing works. 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 putty, the surface is treated with a primer deep penetration. 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 surfaces 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.

You can install tongue-and-groove partitions yourself, because this does not require special skills or knowledge. The material is very convenient to work with and does not require careful preparation surfaces, installation lasts a few hours. Gypsum boards, from which partitions are built, have a number of advantages, and therefore are increasingly used in private construction.

Properties and characteristics

Tongue-and-groove slabs are often used: what is it? This material is a monolithic rectangular gypsum slab mixed with various additives. Features of the slabs are longitudinal grooves and protrusions (ridges) at the joints, providing additional strength to the finished structure. The elements are connected using glue.

Properties of tongue-and-groove slabs:

  • the material is non-toxic;
  • high resistance to temperature fluctuations;
  • have no odor;
  • resistant to rot and insect activity;
  • have high sound absorption;
  • vapor permeable;
  • easy to process with carpentry tools.

For rooms where humidity is high, moisture-resistant GGPs are produced, which differ from ordinary ones in a light green color. During their production, hydrophobic additives are added to natural gypsum, which are absolutely harmless to humans.


Main technical characteristics:

  • standard size - 667x500x80 mm;
  • weight of a hollow slab - 22 kg, solid - 28 kg;
  • density - 1030 kg/m³;
  • compressive strength - 5.0 MPa;
  • bending strength - 2.4 MPa;
  • high fire resistance.

Advantages of tongue-and-groove partitions

Partitions from PGP are assembled according to the principle of a designer, so one person can install about 30 m² in a day. Even if you have no experience, understanding the process will not be difficult; just read the instructions and look at the photos. The main thing is to correctly mark the partition. The advantages of the material are:

  • When installing partitions made of tongue-and-groove slabs, there are no wet processes; wallpapering can be carried out immediately after installation work;
  • with a small thickness, the partitions are distinguished by good strength and thermal insulation;
  • due to the absence of voids in the connecting seams and gaps at the junction with the main wall, sound insulation in the room is improved;
  • the pliability of GGP joints eliminates the appearance of cracks and deformations;
  • The material can not only be wallpapered, but also painted, tiled, and covered with decorative plaster.

Partition installation technology

For 1 m² of a single partition, 5.5 slabs and 1.5 kg of special glue are required. Before starting work, the material must be brought into the room and left for at least 4 hours. The temperature inside the room should not be lower than +5° C.

Additionally you will need:

  • cork gasket;
  • building level;
  • marker and tape measure;
  • container for glue and water;
  • drill with attachment;
  • trowel;
  • rubber hammer;
  • staples made of galvanized steel;
  • self-tapping screws and anchor dowels.

Work begins by cleaning the surface at the junction of the structure. Wallpaper and peeling trim must be removed and large uneven areas smoothed out. cement mortar or putty. If the wall is smooth, the paint (plaster) adheres firmly, it is enough to remove dirt and dust. The floor is prepared in the same way. Next, markings are made on the floor for the partition, and the locations of the openings are marked. Using a level, the marking line is transferred to the ceiling and walls.

Prepare the glue: pour water into a container, add the dry solution, mix with a nozzle and let it sit for 3 minutes. Mixing proportions are indicated on the packaging. U different manufacturers They may differ, so you should read the instructions carefully. Apply a strip of glue according to the markings and apply a cork lining. As soon as the glue sets, you can install the first row of slabs.


A layer of glue is applied to the lining, after which the ridge is cut off long side first slab and install this side down. Level the PGP, coat the side cut with glue and install the second slab. Each fragment must be checked by level, correcting rubber mallet. For the second row, the first slab is sawn in half to offset the vertical joints. For connecting partitions made of tongue-and-groove slabs with load-bearing wall At the junction points, staples are installed. One end of the bracket is fastened with self-tapping screws to the slab, placing it in a horizontal groove, the second is fixed with anchor dowels to the wall. The step of such fastenings is through 2 plates.

When making openings there are also some nuances. If there is only one row of slabs above the opening, and the width is no more than 80 cm, it is enough to place a temporary support until the glue dries. For larger widths, be sure to install a jumper: wooden beam or a metal channel of the appropriate section.

The upper edge of the last row of PGP is sawn at an angle to avoid the formation of voids when filling the seams.


The distance from the edge of the slab to the ceiling should be 1-3 cm. After installing the last element, the gap between the partition and the ceiling is sealed with gypsum mixture or filled assembly adhesive. At this point, the installation of partitions made of tongue-and-groove slabs is considered complete. The fastening of shelves, cabinets, mirrors and other objects to such walls must be carried out taking into account the load exerted. Up to 30 kg/cm, fastening is performed using anchors plastic dowels, for higher values, galvanized bolts are used that pass through the entire thickness of the slab.

Conclusion on the topic

When remodeling an apartment, partitions made from PGP are the most profitable solution. In addition to zoning the space, they create additional sound and heat insulation, which allows you to save on materials. But the main advantage is still considered ease of installation, because the services of specialists are very expensive. If you follow the instructions exactly, carry out each stage efficiently and carefully, the partition will turn out no worse than that of professional builders.

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! Arrangement interior partitions with the help of tongue-and-groove plates it happens 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 listen carefully to the wishes of the customer and implement them taking into account the requirements regulatory documentation. Only trusted companies that provide best quality at low price. 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 required quality not achieve;
  • 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.

When remodeling an apartment or building a private house, you have to install new partitions. Selecting material for them is not so easy. It should not create excessive load on the floor, must be reliable and have good bearing capacity. It is also desirable that the installation be simple and quick, and the price low. There are not many materials and technologies that meet these requirements. These are tongue-and-groove slabs. In this article we will talk about tongue-and-groove ridges.

What kind of material is this and its types

Tongue-and-groove slabs (abbreviated GGP) or blocks - large format construction material for the construction of partitions in the form of a slab, at the ends of which a ridge (tenon) and groove are formed. Hence the name - tongue-and-groove slabs. They are:

Plasticizers and hydrophobic (water-repellent) additives are added to the solution to improve properties. Gypsum gypsum boards have another name - gypsum boards. It is understandable: the gypsum solution is poured into molds. Here is the “source” of this variant of the name.

Moisture resistance and hollowness

Depending on the area of ​​use, tongue-and-groove slabs can be intended for normal operating conditions (ordinary, standard) or for wet rooms (moisture-resistant). Moisture-resistant ones are tinted greenish for better identification.

Both gypsum and silicate tongue-and-groove slabs are either solid or hollow. Solid ones are more durable; hollow ones, due to their lower weight, create less load on the floors. The choice between solid and hollow must be made based on several factors:

  • Soundproofing characteristics. Monolithic material without voids conducts sounds better, so it is used if sound insulation will be made in a separate layer (the best option) or if it is not so important.
  • Loads on partitions. If you need to hang shelves, furniture, or fasten some heavy objects on the walls, it is better to use a monolith.
    • . On wooden floors or on old ones wooden floors It is better to install less heavy (hollow) blocks.

If several factors need to be taken into account, sound insulation is considered in last resort. You can increase noise protection by using special technology installation (on vibration-damping pads), as well as by adding an additional layer of soundproofing materials.

Specifications

If we compare conventional and moisture-resistant tongue-and-groove slabs, the differences in characteristics are only in water absorption and strength. Moisture-resistant, due to the large number of hydrophobic additives, they almost do not absorb moisture. Due to the large number of these additives, they are more expensive, since these additives are expensive. At the same time, they increase strength (M50 compared to M35).

By the way, you can check “without leaving the checkout” whether what you have in front of you is really moisture-resistant PGP or just standard ones painted green. Just pour some water on the surface. Standard slabs it will be quickly absorbed, and on water-repellent ones it will remain in a puddle for a long time.

If we compare gypsum and silicate partition blocks, the increased strength of the latter immediately catches the eye - M150 compared to M50 and M35. That is, the strength of silicate slabs is comparable to concrete of a good grade. If you are going to hang something very heavy on the partition, it is better to use silicate. Manufacturers also produce blocks 115 mm thick, which are called inter-apartment blocks.

How else do silicate slabs differ from their gypsum counterparts? Because the standard version does not have such a high absorbency. It is not as low as that of moisture-resistant blocks, but this material can be used in any wet areas without problems (13% compared to 26-32%). The disadvantages of this material are greater weight (with equal dimensions) and lower thermal insulation characteristics.

Silicate or gypsum?

If we compare the soundproofing characteristics of gypsum blocks and silicate ones, the latter, with equal parameters, conduct sounds worse (40-43 dB for gypsum and 48-52 dB for silicate). So for better sound insulation choose silicate.

But silicate blocks of the same size have greater weight and higher thermal conductivity (they conduct heat better). Weight is key in the choice, since sound and thermal insulation can be improved with additional layers special materials, but there is no way to reduce the weight of the partition. And if its mass is critical for the overlap, nothing good can be expected.

How to build with tongue-and-groove slabs

In order for a partition made of tongue-and-groove blocks to be reliable and stable, certain conditions must be met:


In general, it is necessary to strictly follow all recommendations and strictly follow the technology. Then tongue-and-groove partitions do not differ in strength and reliability from brick ones, but are erected many times faster.

Marking

The laying of the tongue-and-groove wall begins with markings. If you have a laser plane builder, everything is simple: unfold the plane, draw lines on the floor, walls, ceiling. If there is no such tool, you will have to spend more time. A plumb line will be required. The one that won't fit in a smartphone is not measuring tool. It's better to buy from hardware store or make it from twine and a centered weight.

We draw the first line on the ceiling and use a plumb line to transfer it to the floor. By connecting the points on the floor and ceiling, we get lines on the walls. As a result, a closed marking was formed to align the partition.

We inspect the base on which we will place the blocks. It should be perfectly aligned when viewed along the partition line, and should not fall forward or backward when viewed across.

If there are door or window openings in the partition, they must also be marked. With doors everything is simple - we mark them on the floor. It’s more difficult with windows - you need beacons on the walls and ceiling.

Preparing the base

As already said, the base should be perfectly level without tilting in any direction. If there are deviations, concrete floor fill in the leveling screed (not lower than M150). To do this, you will have to assemble the formwork into which the solution is poured. Minimum thickness layer - 3 cm. To get a guaranteed high-quality result, use a self-leveling composition. Just keep in mind that the errors “correct themselves” are not too large. You still need to distribute the composition manually. Simply move the spatula, dispersing the solution along the entire length, and minor irregularities are leveled due to the increased fluidity of the material.

Cover the poured concrete with polyethylene and leave it for about a week. This is if the room temperature does not drop below +20°, during which time it will gain 50% strength. This means that you can work with it. If the temperature is lower, the period increases. At a temperature of 17°C and slightly lower, 2 weeks are already needed... Coat a smooth base with concrete contact - it will improve the adhesion of the base to adhesive composition, on which we will put the GWP.

If tongue-and-groove blocks We will place it on a wooden floor, the partition should go over the beam - this is it. Second, we level the base using dry timber. It must be secured so that it is also horizontally aligned in all directions. We fasten the timber to the floor with nails or self-tapping screws. If there is a joint, we connect it into half a tree, additionally coating the joint with wood glue and fastening it with nails.

To improve sound insulation

The main disadvantage of gypsum tongue-and-groove partitions is that the sound insulation is not very high. The situation with silicate blocks is better, but also not ideal. Therefore, we recommend laying vibration-absorbing tape around the perimeter of the partition. It is no secret that most sounds are transmitted through vibrations through the floor, ceiling and adjacent walls and elastic gaskets significantly improve the situation.

Under tongue-and-groove slabs, you can use a strip of bituminized felt or cork with a density of 250-300 kg/m³. The width of the strip is slightly less than the width of the blocks. It is laid on a leveled base using the same binder that you will use to seal the seams between the slabs. The solution is applied to the surface treated with concrete contact (after drying) in a layer of 2-3 mm. Lay the tape by rolling it with a roller, expelling air bubbles. The protruding solution is removed with a spatula. In this way, the tape is glued to the floor, walls, and ceiling. Levelness is checked using a bubble level.

Preparing slabs for installation

If silicate tongue-and-groove slabs are used, no preparation is required - their upper and lower surfaces do not have a groove/ridge. They are absolutely smooth (as in the photo below).

When working with a gypsum tongue-and-groove, first you need to decide whether you will place the blocks with the tongue or groove facing up. It is more convenient to work when the groove is directed upward, but also reverse position is not an error.

If you decide to lay the PGP with the groove up, you need to cut off the tenon on all blocks of the first row. The most convenient way to do this is with a hacksaw. The resulting cut is uneven. We level it using a plane.

Note! The cut of the slab must be absolutely even. This determines how firmly the wall of tongue-and-groove slabs will stand. And the cut tongue-and-groove slabs must be the same height.

The seam between the blocks does not exceed 2 mm, so it is almost impossible to correct even small deviations. Therefore, we align carefully and carefully. After leveling, the dust is swept away with a brush and you can begin to build the wall.

First row

The sequence of actions when laying a wall made of tongue-and-groove slabs is simple and very similar to a brick one. There are only some features. Since the partition is usually adjacent to the wall, if a tenon is turned towards it, it is cut off with a saw, the surface is leveled with a plane, and the dust is removed. The next procedure is as follows:


In this way the entire row is lined up. The last slab usually has to be trimmed. This could be the beginning of a doorway or simply the last slab in a row. Its length should be 3-4 mm less than the remaining gap - the seam gap. You should not increase the gap - stability will decrease. For greater confidence, the joint can be reinforced with a metal corner. Two or three corners for each row. It's enough.

Second and subsequent

Tongue-and-groove slabs are laid with staggered seams - like bricks. The shift of the second row can be half or a third of the length. The best option- half. We cut half of the whole slab, cut off the tenon if necessary, and install it. Further masonry is no different. The third row again starts with a whole block, the fourth - with a half, etc.

After laying each block, check whether it is positioned correctly. With such block sizes, the error accumulates very quickly. Therefore, we first check each installed block with a level for verticality/horizontalness. and then, placing the bar horizontally, grabbing the adjacent blocks and moving them from top to bottom, make sure there are no gaps. We also check that there are no deviations in the vertical plane.

Control of verticality and horizontality is one of the main tasks

Corner

If the wall being built from tongue-and-groove blocks has outside corner, we start laying from there. To make the work easier, we create a corner support. This could be a corner with fairly wide shelves or two boards connected at 90°C. We put the structure in place, check the correct installation, and temporarily fix it to the ceiling and floor.

We cut off the side tenon of one of the slabs, rest its edge against the installed stop, level it, using a mallet to set the direction. We also cut off the side tenon of the second slab, apply glue to this edge, and join it to the side surface installed slab, tap until there is tight contact (diagram in the figure above).

To install the second row, you need to make a cut in the already installed slab for the lower tenon of the next block. We take a hacksaw for metal and make cuts. Then, using a wall chaser (a tool for working with foam concrete, but it is also useful for laying wiring in the PGP) or any hard tool, we remove the excess, align the groove, making it the same size and shape as the groove. Using a brush or construction vacuum cleaner remove dust.

We place the second row starting from the other side - so that the seam is on the other side of the corner. Apply the solution to the end of the lower block. We take half of the block, cut off the side tenon, and install the bottom one in the prepared groove (far right diagram in the figure below). He must also rest against installed corner. We carefully align the installed tongue-and-groove slabs, checking for verticality and the absence of even the slightest deviation.

Branch

We also need to consider the branch from the partition at a right angle. The partitions will be more reliable if they are made with ligation (middle diagram in the figure). All three slabs that are being installed have the side tenon cut off. The joints are coated with adhesive, and the three blocks are driven close to each other with a mallet. In this case, it is also necessary to ensure that the partition is perpendicular - that is, the angle is 90°.

We line up the second row so that the middle of the block is above the junction. To install it, you will also need to make a groove in the protrusions of the lower block. These rows are then alternated.

There is another way to install a T-shaped partition from a tongue-and-groove - without ligation. To do this, simply lay out the wall (which in the letter T is the top crossbar). TO finished wall, end-to-end, attach a second partition ( left diagram in the figure above). To increase the reliability of the connection, metal reinforced perforated corners are installed at the junction.

Doorway

A doorway in a wall made of tongue-and-groove slabs can be made with or without a reinforcing beam. It can be done without a reinforcing beam if the width of the opening does not exceed half the length of the block. Thus, a doorway 900 mm wide can be made without a beam if the ceiling is made of 900 mm long PGP. Moreover, the joint of the plates should be located almost in the middle. A slight shift is allowed (by 10 mm), but so that the length of the entire part of the block to the right and left of the opening is not less than 445 mm.

During installation, before the glue sets, the lintel above the door is reinforced with a stop (a board supported by a pole resting on the floor) or a structure assembled from boards as in the right diagram. In this case, first assemble a U-shaped lintel from boards and secure it with self-tapping screws to the blocks located below (check the horizontality of the lintel). Apply a block and mark how it needs to be cut. It turns out two L-shaped blocks of the same or almost identical sizes. After applying the solution in the right places, they are installed.

If we use tongue-and-groove slabs 667 mm long, a reinforcing beam must be installed under an opening larger than 660 mm. To make a beam you can use metal corner, channel, fittings, strips of metal of considerable thickness. It is possible to use dry wooden beam thickness 50 mm or more (pre-treat with an antiseptic). The beam should protrude 400-450 mm beyond the doorway.

Partitions made from PGP are used for redevelopment of premises or delimitation of apartments in new buildings. They differ flat surface, ease of installation and low 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 sizes- 667x500x80 mm, thickness can be 100 mm.

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

Their installation occurs very quickly, but you cannot cope with it yourself - due to heavy weight building elements There is a whole team 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 sound 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 plates 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 seal made of cork or felt, edge tape, rope, glue, 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 level, 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 mortar 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.

Used to build a wall acrylic glue based on gypsum.
