HEAT-STRENGTHENED GLASS

The main difference between heat-strengthened glass and tempered glass lies in what happens upon impact or breakage.

Heat-strengthened glass will likely break into relatively large pieces which tend to stay anchored within the glazing system, while tempered glass will shatter into small, roughly cubical pieces that fall from the window frame.

The former may be about 2-3 times as strong as untreated or annealed glass, while tempering will result in a product that can be up to 4-5 times as resistant.
