Among the most important characteristics of a building under construction, in the first place are the duration of construction and the amount of costs, 50% of which are the cost of materials. It is possible to significantly reduce costs through the use of modern construction technologies, for example, the construction of internal partitions from tongue-and-groove slabs. This wall material has long been appreciated by professionals in commercial construction. Those who are engaged in the construction or repair of their homes on their own are reluctant to use it, preferring brick, frame plasterboard structures, etc. As a result, time and money are spent ineffectively, since the market is overflowing with modern inexpensive products, with which labor costs and the cost of work are significantly reduced! To help novice builders minimize costs, bestx.htgetrid.com/en/ offers an overview of the best tongue-and-groove manufacturers for 2020, ”compiled by buyers and experts.

What are tongue-and-groove plates
First you need to understand what it is and get acquainted with the scope of this interesting building material.
Structurally, these are blocks, with grooves and ridges on the mating surfaces.
When erecting partitions, a ridge / groove connection is formed. As a masonry mortar, special compositions based on dry gypsum mixtures are used. Some craftsmen use tile glue.
Important! Ready-made gypsum glue for masonry GWP must be used within 60 minutes, until it loses its mobility.
Depending on the composition, design and moisture resistance, the following types of blocks are distinguished:
- Plaster. Made from a mixture of plaster of paris and plasticizing additives.
- Silicate. For their manufacture, quartz sand, water, quicklime are mixed.
- Corpulent, i.e. monolithic without voids.
- Hollow. Monolithic surface and internal voids of various cross-sections: round of various diameters or rectangular. Hollowness does not reduce the strength of the products. They are lighter than corpulent and easier to handle.
- Moisture resistant, with hydrophobic additives. Can be used in rooms with high humidity.
6. Ordinary, without water-repellent additives. They are used only in dry rooms. When water gets in, they spread out.
The groove / ridge shape in section forms a rectangle or trapezoid. Most often, manufacturers produce blocks of the standard size 667x500 mm, 80 or 100 mm thick.
Some manufacturers produce products of reduced dimensions, for example, 495x248x80 mm. Such blocks are lighter and easier to work with. But they also have a drawback - the absence of a groove / ridge on the horizontal mating surfaces.
Specifications
Before purchasing a GWP, consider the following characteristics:
Density
For gypsum products, it is small, only 1350 kg / m3.However, this is enough to safely attach a dish box or shelf to such a wall. The main thing is not to drill the wall with a puncher and not to pound on the dowel with a hammer. With the correct use of screws and a screwdriver, there will be no problems. The density of silicate blocks is 1870 kg / m3.
Thermal conductivity
Manufacturers declare the thermal conductivity coefficient in the range from 0.040 to 0.045 W / (m ° C). Not a bad indicator that the material keeps heat well. For the construction of internal self-supporting walls made of GWP, the use of heat insulators is optional.
Soundproofing
All manufacturers prescribe a sound insulation coefficient of 45-47 dB. However, do not flatter yourself. When arranging inter-apartment walls, an additional layer of sound insulation will not hurt at all.
Strength
Two characteristics are considered:
- flexural strength for gypsum panels usually does not exceed 2.5 MPa;
- for compression - no more than 5MPa.
Silicate panels have a strength of M 150 or 15 MPa, i.e. they are three times stronger than plaster.
Vapor permeability
In gypsum conventional tongue-and-groove blocks, vapor permeability is high. This explains their ability to absorb significant amounts of moisture. For moisture-resistant panels, this indicator is lowered to a minimum. Gas silicate products also have minimal vapor permeability.
Scope of tongue-and-groove plates
GWP are used in construction, renovation and redevelopment of apartments only for the construction of self-supporting structures. These include interroom and interroom partitions. The latter are often made double, from blocks, 100 mm thick, with an air gap of 50 mm between them.
This technique improves the soundproofing and thermal insulation qualities of the structure. For the construction of capital (bearing) walls, tongue-and-groove blocks are not strong enough and moisture resistant.
Criteria for the selection of tongue-and-groove plates
The choice of one or another type of GWP depends on the purpose of the structure, the strength of its base, the expected load, dimensions, weight and cost of the product.
Moisture resistant
In rooms with high humidity, structures are erected from solid moisture-resistant slabs. They are easy to distinguish from ordinary ones as they have a greenish tint. Made of gypsum with water-repellent additives, they absorb moisture no more than 5% of their own volume.
The hygroscopicity of conventional gypsum products is about 26-32%. The difference is palpable. Silicate GWPs cannot be divided into conventional and moisture resistant ones, since their hygroscopicity is minimal. They are certainly suitable for use in washrooms and bathrooms.
Conventional
They are used to divide the space between dry rooms: rooms and apartments. Application for separation from the common space of bathrooms is permissible only with additional surface treatment with waterproofing and tiling.
Void
For interior structures, it is better to use hollow blocks, gypsum and silicate. They are lighter than full-bodied ones, by 25% (on average). It is easier to handle them and it is easier to do the work by the device of hidden wiring. If the base is a plank floor on logs, it is better not to overload it. In this case, "voids" should be chosen.
Corpulent
The dividing walls are made of 100 mm thick solid panels. Such a design can also be made double, laying the gap with a roll of mineral wool-based material or leaving an air gap. If you have to hang shelves for dishes or books on the wall, it is better to choose full-bodied products. Gypsum is easier to drill, silicate is more durable. The use of plastic dowels for screwing in self-tapping screws is mandatory in both cases.
Silicate
They differ from gypsum in smaller sizes, greater strength and the absence of grooves and ridges on horizontal joining surfaces. On the one hand, it is more convenient to work with them (less weight and dimensions), on the other hand, the absence of a ridge / groove connection in the horizontal plane complicates the work, forcing the master to constantly ensure that the blocks fit in the same plane (do not wag) ...But the hinge of shelves on a structure made of silicate PPG is not difficult.
What to look for
First of all, on the weight of the panel. Products of the same size and type from different manufacturers may differ in weight. A full-bodied standard panel from "Knauf" or "Magma" weighs 28 kg, and the same from "Aksolit" or Peshelan plant - all 35. It is clear that you should choose lighter products.
Gypsum panels are a "delicate" material. It must be transported and stored carefully, otherwise it is impossible to do without chips and cracks. GWP differs from brick by a smooth surface that does not require leveling before painting or wallpapering. Such a finishing operation as plastering is no longer needed. It is enough to putty the joints and apply a thin layer of finishing putty. Incorrect transportation or storage on gypsum panels results in broken corners and edges, chips on the surface, broken ridges and broken grooves. All this will have to be putty and leveled.
Technology for the construction of partitions from GWP
Before starting work, you should make sure that the base under the wall is perfectly flat, with zero slopes. Even small differences in base height will cause cracks in the structure. For better sound insulation, a damper tape made of expanded polyethylene is laid under the first row. It is also laid at the junctions between the GWP and the main wall.
As in a brick partition, tongue-and-groove panels are laid with bandaging. Alignment of vertical seams is unacceptable.
Products are easily cut with a reciprocating saw or a hand saw for wood. It is not difficult to dissolve one or several pieces. If you have to carry out a large amount of work in an apartment building, you won't cut too much with a hacksaw, your hands will fall off. The process needs to be mechanized.
On a note! During repairs with redevelopment, with a large amount of work, you can cut blocks with a grinder with a diamond wheel. The process is accompanied by the formation of a large amount of dust and it is better to carry it out outdoors. This is one of the disadvantages of using gypsum products.
For stacking blocks, special adhesives are used as a solution, which are produced by most of the companies that have established the production of GWP. In wholesale and retail, there are always tongue-and-groove panels and glue to them from one manufacturer.
For connection with the main wall, metal corners and self-tapping screws are used. To give the structure more rigidity, adjacent GWPs are connected to each other with metal plates, laying them through two panels.
The installation locations of the door blocks are not overlapped with jumpers if the opening width does not exceed 900 mm. A gap of 20-30 mm is left between the partition and the ceiling. It can be repaired with the same masonry mortar or polyurethane foam.
