1. "Rock wool board" external wall external insulation system mainly uses hydrophobic rock wool board produced by pendulum method as thermal insulation layer material. It is connected and fixed with base wall by bonding and nailing process. It is a class a non combustible building energy-saving and thermal insulation system composed of plastering glue and glass fiber reinforced cloth, and decorative sand slurry facing layer or coating.
2. System structure mainly includes: adhesive layer, thermal insulation layer, plastering layer, facing layer and accessories. Light functional coating such as facing mortar, decorative mortar or water-based exterior wall coating with good air permeability shall be used for the facing layer.
3. The rock wool board external insulation system has the advantages of low thermal conductivity, good air permeability and high combustion performance. It can be applied to the energy-saving and thermal insulation engineering of new, expanded and rebuilt residential buildings and public buildings, including external insulation of external wall, non transparent curtain wall insulation and fireproof isolation belt of EPS external temperature protection system.
