2400mm Wide Fireproof Rock Wool For Curtain Walls
Our 2400mm wide fireproof rock wool for curtain walls is engineered for large public buildings and super-high-rise curtain wall systems. Breaking traditional size limitations with an ultra-wide 2400mm format, it significantly reduces panel joints, effectively eliminates thermal bridging, and enhances overall thermal performance. Made from high-quality basalt, it offers Class A fire resistance, high thermal efficiency, and stable physical-chemical properties, making it ideal for insulation behind glass, stone, and metal curtain walls.
- Curtain wall insulation for airports, train stations, and convention centers
- Insulation behind glass/stone curtain walls in super-high-rise buildings
- Thermal layers in large-span metal curtain wall systems
- Projects with strict construction schedule requirements

With a width of 2400mm, panel joints are reduced by half compared to standard 1200mm boards, minimizing thermal bridging and improving insulation performance.
Wide-format boards reduce installation time, accelerating curtain wall closure—ideal for tight project schedules.
The rock wool core is Class A non-combustible (melting point >1000°C), with no burning, toxic fumes, or molten droplets, providing reliable fire protection.
High acidity coefficient ensures weather resistance—no powdering, no shrinkage—provide consistent performance.
