Our 1-hour C-class nano-silica composite fire-resistant glass is a high-performance fire-resistant building material independently developed by our company, certified by the national fire department (with fire resistance integrity up to 3 hours). The product utilizes nano-silica composite interlayer technology, effectively blocking flame penetration at 1000℃ temperatures while 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 requirements while also gaining valuable time for emergency evacuation. Suitable for fire-resistant divisions in office buildings, refuge areas in hospitals, and safe corridors in malls, it has been successfully applied in benchmark projects like Beijing Daxing International Airport and is an optimal choice for smart fire protection system components.
