What is Toughened Glass?

Toughened glass, also known as tempered glass, is up to five times stronger than standard  Float Glass, offering the highest impact resistance.   

Float glass is the most commonly used type of glass in New Zealand homes.  This type of glass often goes on to get further treatments or coatings to become different types of glass.  Toughened glass is Float Glass which has been toughened.

Float glass goes through a heat treatment process, to increase its strength. The glass is heated at high temperatures (650°C), then cooled very quickly.  As a result, the outer surfaces go into compression and the interior remains in tension, which gives toughened glass (tempered glass) its strength.   

Toughened Glass is rated as Grade A Safety Glass in accordance with AS/NZ 2208 and other international standards.  It can withstand strong direct impacts and if it does break, instead of breaking into sharp, jagged pieces, it does so into small blunt glass granules.  These granules are less likely to cause injury.  

You can purchase toughened glass cut to size, however before beginning the glass toughening process, the glass must be cut to the desired size.  This is because it cannot be re-worked once toughened.

Benefits of Toughened Glass

  • Thermal Resistance to Breakage  - toughened glass has an excellent heat-withstanding capacity.   It can be used in situations where there is a danger of the glass breaking due to extreme heat.  However, tempered glass is not fire rated and should not be used where fire resistance is also needed.  Toughened glass is the ideal and safe choice for kitchen backsplashes and kitchen shelves.
  • Strength & Resilience - toughened glass can be used in situations where there is a danger of the glass breaking due to strong direct impacts.   
  • Safety - toughened glass ensures that if it is broken for whatever reason then it breaks safely.
