Composite fireproof glass is composed of multi-layer glass original sheet and water-soluble inorganic fireproof glue interlayer, which meets the requirements of fire integrity, fire resistance and heat insulation.

The fire prevention principle of heat insulation fireproof glass is that when a fire breaks out, the special transparent chemicals in the middle of the heat insulation composite fireproof glass absorb a large amount of heat in the flame and foam and expand, and become opaque white together, which can effectively prevent the heat generated by combustion

Conduct from the fire face to the back fire face to prevent the heat radiation of the glass fire face flame from transmitting to the back fire face. In this process, the glass remains intact as a whole, forming a useful barrier that can block the diffusion and extension of high-temperature toxic gas generated by flame, smoke and combustion.

The heat insulation and heat radiation protection functions of composite fire-proof glass can protect the escape or rescue personnel in the area behind the fire surface of the glass from the invasion of high-temperature heat and the burn of heat radiation, and prevent the combustible materials and articles in the area, such as wood products and carpets, from being ignited by high-temperature and heat radiation within a certain period of time.

Composite heat insulation fireproof glass has a strict definition. It requires that the average temperature rise of the back fire surface shall not be higher than 140 ℃ within the required fire prevention time, and the temperature rise at any point shall not be higher than 180 ℃.

The application of fire-proof glass to the design of curtain wall and partition is not to simply change the non fire-resistant materials used in curtain wall or partition to fire-resistant materials, nor is it all right to replace ordinary glass with fire-proof glass, but to consider it as a fire-proof system.

The fire resistance rating of fireproof glass curtain wall and partition can only be determined by comprehensively considering the fire resistance rating of various elements of the whole system. Subjective estimation may make mistakes, and inspection tests shall be conducted if necessary.

When composite fireproof glass is selected in design, attention shall be paid to the corresponding relationship between the size of glass plate and fire resistance rating.
