How to lay a gypsum-fiber sheet on the floor?

GVL sheet: application

This material is used for finishing in the following premises: cellars with air humidity up to 70%, residential, civil, industrial and sanitary buildings( with bathrooms), pantry, attics, attics. Basically, it is used for facing the floor, walls, partitions.

Conventional GVL sheets provide soundproofing, heat-shielding and fire-fighting properties. In some situations, they are recommended to be used instead of drywall. For example, in elevator mines, as well as in industrial buildings, where special requirements for fire safety are imposed. Drywall there will simply be unsuitable.

GVLV it is desirable to apply in those cases when in premises there is an increased humidity. For example, to exclude "wet" floors. It is justified in SNiP II-3.That is why bathrooms, kitchens, cellars and garages are often finished with this material.

Gypsum fiber sheet: technical characteristics and properties of

This material has its characteristics and properties of

.As already mentioned, firstly, it has the ability to maintain the optimum level of humidity in the room. That is, with an excess of a sheet of gypsum fiber absorbs moisture, and if there is a deficit - it secures. Secondly, it is quite strong and durable material, which is used for laying on the floor. Thirdly, it has a low rate of heat build-up. That is why the sheets are always warm to the touch.

Fourth, a high fire safety factor. Fifthly, it provides good sound insulation characteristics. Sixth, it's easy to pack. This greatly reduces the labor costs and timing of installation work. In addition, even more money is saved because of the minimal amount of waste during installation. Seventh, these sheets can be used in buildings with complex configurations.

Of the main characteristics are: density of about 1250 kg / m3;the compressive strength is 100 kgf / cm2, and with bending - 53 kgf / cm2;sound absorption( without using additional insulating material) - 40 dB, fire resistance group G-1, thermal conductivity - 0.36 W / mK.

Make the material in accordance with specifications. It has a hygienic certificate, as well as a certificate of conformity.

Gypsum fiber sheet for floor: a few words about laying

You can lay these sheets on both wooden and reinforced concrete bases. And also on a concrete screed provided that a good waterproofing device is installed. Small plates with a size of 1.5x1 meter and 10-12 mm thick are usually used for assembling. Laying works are carried out in the following order.

• The edge band is fastened around the perimeter. It is designed to compensate for deformation of the structure. At the end it should be cut to the level of the laid floor. Then lay a layer of polyethylene.
• Sprinkled with expanded clay or put a thick insulation. If this is the first material, then it must be leveled and tamped.
• Begin to lay the gypsum board from the corner( which is closest to the door).
• The first layer is covered with PVA glue or MASTICS POLAX .On it lay the second layer of plates.
• Pull them together with screws. Excess glue between the slabs is removed.
• At the finishing stage, the resulting surface is primed and a finishing coat is fixed( for example, linoleum).
