Type A composite fire-resistant glassOur self-developed high-performance fire-resistant building materials have passed the national fire safety certification (retaining integrity for up to 3 hours). The product utilizes nanosilicon composite interlayer technology, effectively blocking flame penetration at 1000℃ temperatures while inhibiting the spread of toxic smoke, with a thermal conductivity coefficient below 0.23W/(m·K). It offers over 92% light transmittance and a shock resistance of 5J/cm², meeting architectural lighting needs and providing valuable time for evacuation. Suitable for fire compartments in office buildings, refuge rooms in hospitals, and safe corridors in malls, it has been successfully applied in benchmark projects like Beijing Daxing International Airport and is the preferred material for smart fire protection systems.
