Addtime：2025-08-14 Hits：2
In modern buildings, fire safety is a crucial consideration. As a high-performance fireproof material, Class A composite fireproof glass not only has excellent fire resistance, but also takes into account light transmission and aesthetics, and is widely used in commercial buildings, hospitals, schools, subway stations and other public places. This article will introduce in detail the features, advantages and application scenarios of Class A composite fireproof glass to help you better understand this safety protection product.What is Class A Composite Fire Rated Glass?Class A composite fireproof glass, also known as heat-insulating fireproof glass, is composed of multiple layers of glass and a special fireproof adhesive layer. In high-temperature environments, the middle layer expands rapidly to form a dense insulation layer, effectively blocking flames and heat radiation, ensuring that the temperature of the backfire surface does not exceed the standard requirements, thereby buying valuable time for personnel evacuation and fire rescue.Core features:✅ High fire resistance limit: up to 0.5 hours to 3 hours (such as A60, A90, A120, etc.).✅ Strong thermal insulation performance: effectively reduce the temperature of the backfire surface and prevent heat radiation damage.✅ Good light transmission: Maintain natural lighting without affecting the aesthetics of the building.✅ Strong impact resistance: The multi-layer composite structure enhances the overall strength and reduces the risk of chipping.✅ Environmental protection and safety: no harmful substances are released, meeting building safety standards.Class A composite fireproof glass vs ordinary fireproof glassComparison Class A Composite Fireproof Glass Ordinary Fireproof Glass (Class C)Excellent thermal insulation performance ✔ (low temperature on the back fire surface) ✘ Average (flame protection only)Fire resistance time 0.5-3 hours usually ≤ 1 hourApplicable scenarios High-rise buildings, densely populated areas Places with low fire prevention requirementsPrice Higher (high safety) Lower (basic fire protection)Class A composite fireproof glass far exceeds ordinary single piece fireproof glass (Class C) in terms of safety, especially suitable for places with strict fire protection requirements.Application scenarios of Class A composite fireproof glassCommercial buildings: office buildings, shopping malls, hotel fire protection zones and escape routes.Public facilities: subway stations, airports, hospitals, schools and other densely populated areas.Industrial Plants: High-risk environments such as chemical plants and data centers.High-end residential projects: fireproof door and window design for villas and high-end apartments.How to buy high-quality Class A composite fireproof glass?Certification: Check whether it has passed the GB 15763.1-2009 national standard and international certification (such as EN, UL).Examine fire resistance ratings: Choose A60, A90, or A120 grades based on building needs.Choose a reliable brand: Well-known manufacturers (such as CSG, Xinyi, Saint-Gobain, etc.) have more guaranteed quality.Customized services: Support customization of size, color, and thickness to meet different architectural design needs.Conclusion: Protecting safety starts with the choice of Class A composite fireproof glassClass A composite fireproof glass has become the preferred solution for modern building safety protection due to its excellent fire and thermal insulation properties. Whether it's a new construction project or a renovation project, choosing high-quality fireproof glass is building a solid barrier for life and property.Consult a professional fireproof glass supplier today to protect your building safety!
