The dimensions of the tongue-and-groove slabs should be known to all people who decide to use this advanced material for construction purposes. Having figured out exactly what thickness the tongue-and-groove blocks for partitions and capital structures are, you can eliminate many mistakes. Plaster GWP 80 mm and other variants of such elements play an important role.

What do the dimensions depend on?

The use of tongue-and-groove plates is in demand due to the natural chemical composition and reliability of such products. But before buying a specific product, you will have to carefully study its features. As with any rigid building material, the size range is important . And he, in turn, depends on various points and nuances. The main consideration in determining the size of the blocks is the optimal ratio of labor intensity, comfort, reliability and cost of construction work.

Wall blocks made of gypsum blanks can differ significantly from silicate modifications . A plaster structure with dimensions of 0.667 m long and 0.5 m high successfully replaces 20 single red bricks. Silicate models will replace only 7 bricks, but this will also significantly speed up work and reduce costs.

For GWP, the dimensions do not always differ depending on the degree of moisture resistance. So, conventional structures most often have a value of 0, 665x0, 5x0, 08 m, but for blocks that resist moisture, this indicator may coincide.

Gypsum plates with groove-ridges are somewhat larger than similar products on a silicate basis . This is directly related to their reduced specific gravity. Dimensions may vary depending on the technology used by a particular manufacturer. Important: the presence of internal voids does not affect the linear dimensions of the product. It is much more important that thinner blocks are used for interior partitions than for main walls.

How to choose?

It is important to understand that tongue-and-groove slabs can be external or internal. Outside are made only of aerated concrete. Even with a strict coincidence of sizes, they are not interchangeable with silicate and gypsum products . But they steadily save heat, are fireproof, do not need reinforced reinforcement and are distinguished by excellent sound insulation. Internal tongue-and-groove blocks are recommended for interior partitions - if they are hollow and for serious walls - if they are made in a monolithic manner.

Moisture resistant products are intended for places with increased accumulation of dampness . They allow you to maintain optimal temperature parameters in the room. The main part of such slabs has dimensions of 50x25, 66, 7x50 cm. The width in different versions will be 8 or 10 cm.

It is also necessary to pay attention to the difference between gypsum and silicate boards, which are formally similar in size.

Gypsum provides an attractive appearance . It doesn't even have to be trimmed. If you wish, you can glue the wallpaper, apply decorative plaster or paint immediately after installation. Gypsum GWPs are mounted quite simply and quickly - they are just glued together. If necessary, you can easily saw and plan the workpieces, besides, they are completely safe for nature and humans.

Silicate modifications have their advantages:

• absolute smoothness;
• reducing the cost of building partitions and walls;
• strength;
• increased reliability;
• improved sound insulation;
• much less risk of deformation;
• no need to plaster the surface.

The thicker the material, the greater, other things being equal, its sound insulation. So, for example, a wall made of 667x500x100 elements provides much more confidentiality of what is happening in the house than 667x500x80. Hollow core slabs should be used as much as possible. Their installation is significantly cheaper and faster than that of full-bodied counterparts. Finally, it is worth considering the load on the foundation - for hollow versions it will be 25% less than for full-weight products with the same dimensions.

Common sizes

Frequently encountered linear parameters of the GWP block are 50x25x7 cm. The height of both the main walls and partitions cannot exceed 4 m. As for the thickness of 8 cm (a number of manufacturers designate it as 80 mm), this dimension was widely used even before 1991 . Until now, a large part of domestic firms are trying to apply the same usual value. Even foreign manufacturers sometimes follow their example.

The thickness of 100 mm is typical mainly for insulated products designed for the northern regions of the country. The production of tongue-and-groove slabs in our country is regulated by state standards (GOST 6428-2018 is valid for 2020). Important: the standard does not apply to gypsum structures with a thickness of less than 5 cm, as well as to wall slabs to the height of the entire floor. The nominal dimensions according to the standard should be as follows:

• 90x30x10 (8);
• 80x40x10 (8);
• 66.7 cm long, 50 cm wide and 10 (8) cm thick;
• 60x30x10 (8) cm.

The maximum deviation level (in both directions) can be equal for a length of 0.5 cm, for a width of 0.2 cm, for a thickness of 0.02 cm. by the consumer. In this case, all other technological parameters must also be recalculated. Knauf is ready to supply gypsum tongue-and-groove slabs in the following sizes:

• 0.667x0.5x0.08 m;
• 0.667x0.5x0.1 m;
• 0, 9x0, 3x0.08 m.

The Volma company implements hollow structures with a size of 667x500x80 mm. Its full-weight samples can have the same thickness, but there are also 10-centimeter versions.

If you need to purchase silicate GWP, you can refer to the range of KZSM. It includes slabs:

• 0, 495x0, 07x0, 248 m (full-bodied moisture-resistant version);
• 0, 495x0, 08x0, 248 m (simple tongue and groove);
• 0, 495x0, 088x0, 248 m (reinforced moisture-resistant sample of full-weight type).

There are offers from other companies:

• 498x249x70;
• 498x249x80;
• 498x249x115;
• 248x250x248 mm.
