High-strength monolithic fireproof glass is a kind of "deep special tempering" made of soda-lime-silica float glass as raw material, which has good light transmission performance, and can withstand flame impact several times as much as ordinary tempered glass (it can not burst for more than 90 minutes under the flame impact of up to 1000℃, thus gaining valuable time for people to escape and rescue work), and its surface compressive stress is much higher than that of ordinary tempered glass, generally above 160MPa, while that of ordinary tempered glass with the same thickness is 90MPa. High-strength monolithic fireproof glass has fire-resistant integrity, neither heat insulation nor heat radiation protection, and belongs to Class C fireproof glass.
