Heat-treated Glass
You are interested or you are having questions?
Tempered Glass
Heat-treated glass is heated in an oven at a high temperature and then cooled rapidly by blowing air onto both surfaces. The cooling process locks the glass surfaces in a state of compression while the core is in compensating tension. The compression of the tempered glass surface is greater than 10,000 psi (68.9 MPa), therefore meeting the ASTM C1048 standard.
CHARACTERISTICS
- Fully tempered glass is about four times stronger than annealed (non-tempered) glass of the same thickness.
- Glass breaks into small, dull fragments ensuring the protection of individuals.
- Provides increased resistance to wind and snow loads as well as high thermal stresses.
- Meets the requirements of Safety Glazing Standards.
- The glass maintains its colour, its chemical properties as well as light transmission properties after it has been heat-treated.
