Our fireproof rock wool core is engineered for metal sandwich panels used in large-span steel structure roofing. This advanced thermal and fire protection material features a lightweight high-strength formulation that reduces roof load while maintaining superior insulation performance.
The core provides excellent water and moisture resistance, and when laminated with metal facings, effectively prevents condensation to maintain dry interior environments. Meeting Class A non-combustible fire standards, it does not burn or emit toxic fumes, making it the ideal core material for industrial facilities and large-scale structures.
