Rock Wool Lamella

Rock wool lamella is manufactured by cutting rock wool board. It has functions of high intensity, compression resistance, thermal insulation and fireproofing. It can be used as filling materials of steel structure’s color steel plate for fireproofing and thermal insulation of the walls and ceilings. Through quick gluing to finalize the design, it can be the high quality and oecumenical building materials with functions of thermal insulation, sound absorption and safety.
