Features and functions: the composite glass of our company belongs to grouting composite glass, that is, it is composed of two layers of glass and interlayer fire-proof glue. It is class A with fire-resistant integrity and heat insulation. It has good fire-proof and heat insulation and high transparency. Under the same thickness, it has longer fire-proof time and higher transparency than other similar products. Under the same fire-proof time, it has thinner thickness?; The thickness includes 15mm, 18mm, 19mm, 20mm, 23mm, 25mm, 26mm, 32mm, 36mm, 42mm, 50mm, etc; Fire and heat insulation time: 30 minutes, 45 minutes, 60 minutes, 72 minutes, 90 minutes, 120 minutes, 180 minutes, etc. Our company has bs476 series of fireproof glass.

Principle of fire prevention and heat insulation: the fire prevention and heat insulation of composite glass is because the glass on the fire receiving surface of composite glass bursts in case of fire, adheres to integrity under the bonding action of interlayer fire-proof adhesive, and adheres to the temperature resistance and flame retardancy of the whole glass when foaming in case of heat, forming a heat preservation and shielding function, which not only stops the extension of open fire, but also ensures that the glass on the back fire surface will not rise in temperature and avoids the spontaneous combustion of surrounding combustibles.
