Hebang exterior wall rockwool boards are applicable to the decoration coats of various wall appearance. With properties like non-hygroscopic, aging resistance and lasting stable performance, they can improve the heat insulation, sound insulation and fire resistance of exterior wall and provide heat preserving systems of exterior wall with high moisture permeability as well.
Hebang exterlor wall rockwool boards give off neither heat nortoxic fumes, so they have excellent fire resistance and can effectively avoid flame spreading in fires. In addition, they havelight weights and can be easily machined by cutting and sawing.
