Gypsum tongue-and-groove hollow slab, 80mm VOLMA

PGB VOLMA are gypsum boards made from environmentally safe natural material using casting technology. The boards are produced in a rectangular shape, with a groove or tongue on the joining surfaces. The hollow tongue-and-groove board VOLMA is a rectangular parallelepiped with grooves and tongues on the supporting and joining surfaces. According to TU 5742-003-78667917-2005, the boards are made from gypsum binder with the addition of plasticizing and hydrophobic additives using casting technology and are intended for the construction of partitions in buildings and premises of various purposes with dry and normal humidity operating conditions according to SP 50.13330. Made from environmentally clean natural material, they are non-combustible, do not contain toxic substances, have no odor, and possess high sound insulation capability and high vapor and gas permeability. The perfect surface and geometric accuracy of the tongue-and-groove boards eliminate the need for plastering work. The process of assembling a wall from such a board is similar to the principle of a LEGO toy constructor, where the products are connected by interlocking the groove and tongue. For fixing the boards, gypsum adhesive "VOLMA-MONTAZH" or "VOLMA-MONTAZH MOROZ" is used at negative temperatures.
