Product Center > High end wall rock wool board > Rock wool external wall insulation system

       Blessed rock wool is made of natural basalt by high temperature melting, centrifugal injection and pendulum method. It is nonflammable, non-toxic, low thermal conductivity, hydrophobic, sound absorption, physical and chemical stability and so on. Combining with its strong vertical tensile strength, the wall of the base layer is connected and fixed by a combination of sticking nails, and the protective layer is composed of plastering mortar and reinforced glass fiber mesh cloth. Finally, a stable exterior wall insulation system is formed by using decorative mortar or coating as the exterior decorative surface.

Scope of application

———————————————————————————————————————————————————————————————————————————————

It is mainly applied to the thin wall plastering system of rock wool.

It is suitable for external thermal insulation system of non transparent curtain wall.

As external wall insulation system, such as fire isolation belt and fire retaining beam, etc.

Other places with high requirements for fire protection, thermal insulation and waterproof.
