The "rock wool board" exterior wall insulation system mainly uses the hydrophobic rock wool board produced by the pendulum method as the insulation layer material, which is connected and fixed to the base wall by a combination of gluing and nailing, and is composed of a plastering layer composed of plastering mortar and reinforced glass fiber mesh cloth, and a decorative mortar finishing layer or paint to form a non-combustible building energy-saving insulation system

The system structure mainly includes: bonding layer, insulation layer, plastering layer, finishing layer and accessories. The finishing layer should use lightweight functional coatings such as finishing mortar and decorative mortar or water-based exterior wall paint with good air permeability.

The rock wool board exterior wall insulation system has the advantages of low thermal conductivity, good air permeability and high combustion performance level. It can be used in energy-saving and insulation projects of new, expanded and renovated residential and public building exterior walls, including exterior wall insulation, non-transparent curtain wall insulation and EPS external insulation system fire isolation belt.
