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. In case of fire, the special transparent chemicals in the center of the heat-insulating composite fireproof glass absorb a large amount of heat in the flame

The foam expands and becomes opaque white together, which effectively prevents the heat generated by combustion from transmitting from the fire facing to the back fire surface, and prevents the heat radiation of the flame on the glass fire facing surface from transmitting to the back fire surface. In this process, the glass is intact, forming a flame barrier.

Smoke and combustion occur as a useful barrier for the dispersion and extension of high-temperature toxic gases

The heat insulation and heat radiation protection functions 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 thermal radiation, and 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 guard 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 external curtain walls, so the combination of fireproof glass and PVB laminated glass should be considered when making the design scheme
