Tempered Glass

Tempered glass is a type of heat-treated glass that is much stronger than ordinary annealed glass. Federal specifications state that fully tempered glass must have a surface compression of 10,000 PSI or an edge compression of 9,700 PSI or more. The typical breaking stress of tempered glass is around 24,000 PSI, compared to 6,000 for annealed glass.

Tempered glass is used mostly for its exceptional strength. In fact, a missile impact generally must have a velocity of at least sixty feet per second in order to break a sheet of tempered glass, compared to thirty feet per second for annealed glass.

In addition to its strength, tempered glass is often used for its safety characteristics. Fully tempered glass typically breaks into small rectangular pieces, reducing the danger that can be caused by glass breaking into small, irregular shards. For this reason, tempered glass is used in construction and automobiles. If it is used alone, however, it does not provide good security, as any break will tend to shatter the entire panel.
