Toughened glass is an extremely strong glass which has been thermally heat treated
to induce compressive stresses.
Tempered glass is being used increasingly in architecture because of strength and
safety properties. It is usually installed in
areas to reduce the possibility of mechanical or thermal breakage and/or to assure
greater uniform load strength.
Best Quality toughened glass is made by using latest technique of forced convection
type furnace.
Characteristics
Strength
Toughened glass is 4-5 times stronger that equivalent thickness of
annealed float glass.
High Thermal Shock Strength
Toughened glass provides greater thermal strength.
Safety
Toughened glass is very difficult to break but even on breakage, it
will break into small, relatively
harmless fragments. This substancially reduces the likelihood of
injury to people as there are no jagged edges
or sharp corners which are normal in the case of breakage of
annealed glass.
