Toughened or tempered glass is glass that has been processed by
controlled thermal or chemical treatments to increase its strength
compared with normal glass. Tempered glass is made by processes
which create balanced internal stresses which give the glass
◆Safety: It will usually shatter into small fragments instead of
sharp shards when broken, making it less likely to cause severe
injury and deep lacerations.
◆High Strength:Toughened glass is typically four to six times the
strength of annealed glass.
◆It is used when strength, thermal resistance and safety are
◆In commercial structures it is used in unframed assemblies such as
frameless doors, structurally loaded applications.
◆Used in a variety of demanding applications, including passenger
vehicle windows, glass doors and tables, refrigerator trays, as a
component of bulletproof glass, for diving masks, and various types
of plates and cookware.
