2-hour Type A composite fire-resistant glassOur company's independently developed high-performance fire-resistant building materials have passed the national fire safety certification (with fire resistance integrity for 3 hours). The product utilizes nanosilica composite interlayer technology, effectively blocking flame penetration at 1000°C and inhibiting the spread of toxic smoke, with a thermal conductivity coefficient of less than 0.23W/(m·K). It offers over 92% light transmittance and a shock resistance of 5J/cm², meeting architectural lighting needs while also providing valuable time for personnel evacuation. Suitable for fire-resistant divisions in office buildings, refuge areas in hospitals, and safe passages in shopping malls, it has been successfully applied in benchmark projects like Beijing Daxing Airport and is an optimal material for smart fire protection systems.
