Xuanming external wall insulation rock wool strip is mainly used as a fireproof insulation material in the external wall insulation thin plastering system and dry hanging curtain wall insulation system of new construction, expansion, and existing building renovation. It can also be applied to the fireproof isolation strip of insulation systems such as EPS, XPS, and PU with combustion performance not reaching Class A, to improve the fireproof performance of building external wall insulation systems. This product can also be used for fire prevention, insulation, and sound absorption on garage roofs or indoor ceilings.
