It has a strength that is about 4 times higher than that of regular glass, so the breakage rate is low, and even if it breaks, it shatters into non-sharp particles, reducing damage from glass fragments.

Ordinary plate glass may be damaged if the temperature difference is 60℃, but tempered glass has high thermal shock resistance that can withstand a temperature change of 200℃.

By suppressing the size of the internal stress of plate glass within a certain range through appropriate heat treatment, the damage state is similar to that of regular glass without heat treatment, but the strength coefficient value used to calculate wind pressure resistance is about twice as high, so it is used in places where wind pressure design is required.
