Operation principle of fireproof glass door

Fireproof glass door is also known as glass fireproof door. In addition to the internal frame structure of the product, large-area fireproof glass is selected.

It can also prevent the heat generated by combustion from being transmitted from the fire to the back fire surface, and block the transmission of thermal radiation, so that the escape or rescue personnel in the back fire surface area can be protected from the damage of high temperature, toxic gas and thermal radiation, and prevent the combustible materials in the back fire surface area from being ignited by high-temperature thermal radiation within a certain period of time
