Tempered glass is made from normal annealed glass via a thermal tempering process in which the glass is subjected to heat till its softening point and then rapidly cooled. This gives the glass its strength. A fully tempered glass is 4 to 5 times stronger then an annealed glass of similar thickness.
A fully tempered glass is regarded as a safety glass and when it breaks it disintegrates into small blunt pieces which greatly reduces the chances of injuries and if there are any then they are superficial in nature.
Over 90% of the glass we supply is safety-tempered glass. We have perfected the process of tempering glass to meet stringent safety requirements and quality standards, while still achieving superior turn-around times for each customer.
Why Use Tempered Glass
Tempered glass is often used by builders because it can satisfy building code requirements for safety.
Builders and home improvement contractors use products with tempered glass for patio doors, storm doors, windows in doors, skylights, shower and tub enclosures and other features.
Vehicle manufacturers use tempered glass for the back and side windows. Windshields, in contrast, are constructed of laminated glass to prevent them from breaking.
Commercial uses include escalator and stairway barriers, sloped glazing, telephone booths, racquetball courts and solar panels.
Tempered glass is used to construct many household items, such as coffee carafes and baking dishes such as those manufactured by Pyrex and Corelle.
Tempered glass also is used in computer screens and oven windows.
