  • dolomite;
  • slag mineral wool.

Thin filament insulation is stretched on special machines, stacked in shape and are fastened together by a special resin. Thereafter, the blank is sent to furnace for polymerization.


Houses and apartments, insulated with mineral wool, have excellent sound and thermal insulation properties, and the thick plates allow you to hide these wall defects, such as curvature and roughness. Also to the material peculiar advantages which distinguish it from the rest:

  1. Low thermal conductivity. Depending on the density and thickness of the sheets, this value can range from 0.055 to 0.11 W/m*K;
  2. Breathable structure. Due to its porous texture, mineral wool is breathable and enables the house to breathe ;
  3. the Absorption of noise. Mineral wool drowns out all other sounds, allowing the homeowners to remain in relative silence, which is very important for families with young children;
