As a fire-resistant and thermal insulation material, rock wool board for external wall insulation is mainly used in thin plastering systems and dry hanging curtain wall insulation systems. It has good compressive and tensile strength, excellent hydrophobicity and moisture resistance, and is suitable for various dense structures such as masonry or concrete base walls. It can be used for external insulation of newly built and expanded walls, as well as for energy-saving renovation of external wall insulation of existing buildings. The A-level non combustible fire rating and high temperature shrinkage resistance can maintain the stability of the system structure in the event of a fire.
