3-hour Type A composite fire-resistant glassOur independently developed high-performance fire-resistant building materials have passed the national fire certification (with fire resistance integrity of up to 3 hours). The product utilizes a nano-silicon composite interlayer technology, effectively blocking flame penetration at temperatures up to 1000°C, while also inhibiting the spread of toxic smoke. Its thermal conductivity is 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 emergency 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 International Airport. It is the preferred material for intelligent fire protection systems.
