Our 1-hour A-class composite fire-resistant glass is a high-performance fire-resistant building material independently developed by our company, having passed the national fire safety certification (with fire resistance integrity for 3 hours). The product utilizes nano-silica composite interlayer technology, effectively blocking flame penetration at temperatures up to 1000°C while inhibiting the spread of toxic smoke, with a thermal conductivity coefficient below 0.23 W/(m·K). It boasts 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 scenarios such as fire separation 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 and is the preferred material for smart fire protection systems.
