Toughened Glass

Toughened glass offers added strength and significantly higher compressive stress than annealed glass of the same thickness. This results in increased resistance to impact breakage, improved ability to withstand uniform loads and decreased chance of thermal stress breakage. When broken, it shatters into many small fragments which prevent major injuries.
 

This type of glass is required in areas at high risk of human impact such as bathrooms, glazed doors and windows taller than 1500mm in height. The Australian Building Code details these requirements. Please ask your Rylock representative for further information.

There are two different methods used to produce tempered glass:

  • Heat Treating: Where the annealed glass is subjected to a special heat treatment in which it is heated to about 680°C and afterwards cooled.
     
  • Chemical Strengthening: The glass is covered by a chemical solution which produces a higher mechanical resistance. Chemically - strengthened glass has similar properties to thermal-treated glass.
