Tempered Glass

Tempered glass is about four times as strong as annealed glass of the same type and thickness.

When broken, tempered glass fragments are usually relatively small and less likely to cause serious injury, so it is classified as a safety glass. Architects may specify tempered glass for commercial or architectural projects, however, tempered glass may also be heat soak tested, in order to minimise the risk of spontaneous breakage.

Tempered glass cannot be cut or drilled after tempering and any alterations such as edge grinding, sand blasting or acid etching will weaken the glass and can cause premature failure.

Our Advanced Architectural Glass is designed so it can be tempered by our network of independent SunGuard Select Processors. That means processing can be done more quickly and nearer to your project site, ensuring shorter lead times and faster replacements.
