When a fire breaks out, the heat rises to 1000℃ in a short period of time, and the smoke and fire caused by incomplete combustion makes it difficult to move to an evacuation area. However, heat-insulating fireproof glass blocks smoke and flames from a fire and also blocks radiant heat. There are no restrictions on passing by glass in the event of a fire. And by blocking the transfer of heat, it can prevent casualties and prevent fires from spreading to adjacent areas.
