Our 2-hour C-class nano-silica fire-resistant glass is a high-performance fire-resistant building material independently developed by our company, having passed the national fire certification (with fire resistance integrity of up to 3 hours). The product utilizes nano-silica composite interlayer technology, effectively blocking flame penetration at 1000℃ temperatures, while also inhibiting the spread of toxic smoke. Its thermal conductivity is below 0.23W/(m·K). It offers over 92% light transmittance and a shock resistance of 5J/cm², meeting both architectural lighting needs and providing valuable time for personnel evacuation. Suitable for fire divisions in office buildings, refuge areas in hospitals, and safe corridors in shopping malls, it has been successfully applied in benchmark projects like Beijing Daxing Airport and is the preferred material for intelligent fire protection systems.
