Rock wool composite board

Rock wool composite board is a kind of inorganic fiber board. Basalt is heated at high temperature, melted and drawn into fibers, and then made into a board. Rock wool composite panels are very dimensionally stable and will not stretch, shrink or deform when heated. The rock wool composite board has a smooth surface and no scars, and is an ideal thermal insulation and exterior wall material. The melting point is higher than 1000 ℃, and no harmful substances and gases will be released in the fire. It is an ideal building insulation material, and its fire rating reaches Class A.
