The composite fireproof glass is composed of two or more layers of glass original sheet and one or more layers of water-soluble inorganic fireproof glue interlayer. When a fire breaks out, the particularly transparent chemical substances in the center of the heat-insulating composite fireproof glass absorb a large amount of heat in the flame and expand into opaque white together, which can prevent the heat generated by incineration from being transmitted from the fire facing surface to the back fire surface, and prevent the heat radiation of the flame on the fire facing surface of the glass from being transmitted to the back fire surface. In this process, the glass is intact, forming an insulating flame.

Smoke and high-temperature toxic gas from burning attack are dispersed and extended as a useful barrier. The heat insulation and heat radiation function of composite fire-proof glass can protect the escape or rescue personnel in the glass back fire area from the harm of high-temperature heat and the burn of heat radiation during the fire attack, and together prevent the combustible materials and articles in the area, such as wood products and carpets, from being ignited by high-temperature thermal radiation during the watch time.

The application scope of the composite fireproof glass includes fireproof doors and windows of building rooms, corridors and passages, fireproof partitions and fireproof partitions in important parts. Most of them are applicable to external windows and curtain walls, so the combination of fireproof glass and PVB laminated glass should be considered when making the design scheme
