“ShengdingYuan” brand special rock wool belt for external wall heat insulation system have excellent property of sound absorb & noise reduce, fireproofing & heat insulation. Meanwhile, it is have good pressure resistance and Tensile Strength and good property of hydrophobic and humidity resistance. It can compatible with building wall because of its enough dimensional stability and chemical stability, same life with building. It is used for new building, building expand and existing building remake.
