Heat-treated Glass

Heat Strengthened Glass
The process of heat-treating used to manufacture heat-strengthened glass involves heating the glass in a high-temperature furnace and then cooling both surfaces with air. The surface compression of heat strengthened glass reaches 3500-7500 psi (25-50 MPa). Heat-strengthened glass cannot be considered as a safety glass.
CHARACTERISTICS
- Its strength is approximately two times that of annealed (non-tempered) glass of the same thickness.
- It offers increased resistance to wind and snow loads as well as high thermal stresses.
- Glass breaks into large, slightly sharp fragments
- When broken the adhesive applied over the surfaces holds the glass together, providing a temporary fix until the pane is replaced
- The glass maintains its colour, its chemical properties and its light transmittance after heat treating
