Tempered Glass

Tempered glass is manufactured, through a thermal process, by heating up the annealed float glass to its softening point and then rapidly cooling it by simultaneously applying a uniform blast of air on both surfaces. 

 

Tempering puts the outer surfaces into compression and the inner surfaces into tension. The additional stresses created within the glass increase its strength such that it becomes 4 to 5 times stronger than that of annealed glass of equal thickness. Such stresses cause the glass to shatter into small granular pieces when broken as opposite to sharp pieces thus reducing the risk of serious injury. It also offers greater protection to lives than annealed glass and is therefore classified as safety glass.
 
Applications: Frameless tempered glass facades, curtain wall, shop front, windows, showers, interior partition, balustrades, panoramic elevators etc…
