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.
- 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.
