Class A Fire Rated Rockwool Roof Panels for Ultimate Passive Fire Protection

Rockwool sandwich panels for roof

The Rockwool Sandwich Panels production process adopts the colored steel plate as surface board and the core material is the self-extinguishing closed-cell rock wool, it is a kind of high–strength composited building material, and it was formed in the automated continuous molding machine, by combining the pressed colored steel with high strength adhesives. Rockwool sandwich panels have excellent fire performance because the color steel plate and rock wool materials are fireproof best.

The unique fire-proof polyurethane/ PIR side sealing technology improves the airtightness and water tightness of the lap joint, effectively preventing the occurrence of the cold bridge phenomenon. At the same time, the occurrence of peeling of the steel plate and the core material at the lap joint during the handling of the sheet is avoided.
