Class A1 Non Combustible Fireproof Rock Wool For Ventilated Facade
Our Class A1 non-combustible fireproof rock wool board for curtain walls meets the highest non-combustible material standard (Class A1) and is specially engineered for curtain wall systems with stringent fire safety requirements. Made from high-quality basalt through advanced processing, it does not burn, melt, or emit toxic fumes during fire, effectively preventing vertical flame spread through the gap between base wall and curtain wall system.
With excellent thermal insulation performance, it is the preferred choice for super-high-rise buildings, refuge floors, and critical public facilities.
- Fireproof insulation for various ventilated facade buildings
- Curtain wall insulation around refuge floors and fire compartments
- Hospitals, schools, data centers, and other occupied facilities
- Projects with strict fire safety inspection requirements

Certified Class A1 non-combustible: no burning, no molten droplets, no toxic fumes—fundamentally preventing vertical fire spread in curtain walls.
100% inorganic mineral fibers emit no carbon monoxide, hydrogen cyanide, or other toxic gases during fire, ensuring safe evacuation.
High acidity coefficient ensures corrosion and aging resistance—fire rating never degrades over the building's lifetime.
Low thermal conductivity achieves both fire safety and energy efficiency goals.
