Glasswool slab(board) are board materials made from superfine glass wool felt with addition of phenol resin cementing agent forming shapes through solidification under pressure and heating．The surface may be coated with PVC film or aluminum foil or glass cloth or aluminum foil glass cloth. Glasswool slab is a kind of economical insulating material which is light and easy to install. This material has excellent performance of sound absorption and good elasticity.

Applications:

Glasswool slab(board) has very good elasticity,compressive strength and tensil strength. It is mainly used as lining of inner & outer walls of cold storage room, warehouse, aircondictioner, ventilating ducts; and it is also applicable to sound, heat insulating and fire prevention of TV station, broadcasting station, etc. Widely used  in heat & sound insulation of office  building, hotel, public place of entertainment,inner wall, ceiling and roof, airconditioner room and cold storage room.
