These are gas silicate blocks marked PORISTON D400 (density D400). The peculiarity of the shape of these blocks is that with a thickness of more than 200 mm they have a special structure of the end faces, which not only facilitates installation, but also reduces glue consumption, since vertical seams can be left unfilled. In addition, these wall blocks have special "pockets" that allow you to conveniently take each block with your hands.
PORISTON D400 aerated concrete is high-quality blocks made of porous concrete with impeccable geometry. These blocks have impressive thermal insulation properties. For example, external walls built from PORISTON D400 375 blocks have the same heat-retaining properties as a brick wall 380 mm thick with additional insulation with a mineral wool slab or 100 mm of expanded polystyrene. Thus, PORISTON D400 aerated concrete allows you to obtain warm walls of smaller thickness without using additional insulation.
