HEAT TREATED &

TEMPERED GLASS

Broken Heat
Strengthened Glass

Broken Fully
Tempered Glass

There are two kinds of heat-treated glass, heat-strengthened and fully tempered.

Heat Strengthened Glass

Heat-strengthened glass is twice as strong as annealed glass of the same thickness, size and type. If broken, heat-strengthened glass will break into large shards similar to annealed glass. Heat-strengthened glass is not suitable for safety glazing as defined by ANSI Z97.1.

Fully Tempered Glass

Fully Tempered Glass is typically four times stronger than annealed glass and two times as strong as heat-strengthened glass of the same thickness, size and type. In the event that fully tempered glass is broken, it will break into fairly small pieces, reducing the chance for injury. In doing so, the small glass shards make it more likely that the glass will become separated from the opening. The minimum surface compression for fully-tempered glass is 10,000 psi. In addition, it complies with the safety glazing requirements as outlined by the American National Standards Institute (ANSI) Z97.1
