Glass Tempering is the process to create safety glass

Safety glazing can offer you so much

Properties of thermally toughened safety glass:

Mechanical Strength

In general the strength can be increased to as much as four to five times that of the equivalent thickness of annealed glass. However, the thermal toughening process does not affect the modulus of elasticity of the product and care should be taken to limit excess deflection.

Thermal Strength

It offers greatly increased resistance to both sudden temperature changes and temperature differentials up to 200K compared with annealed glass, up to 40K. The stress characteristics of toughened safety glass, of normal soda-lime silica composition, are unchanged for continuing service up to 250°C


In the event of breakage thermally toughened safety glass fractures into numerous small pieces, the edges of which are generally blunt.

Thermally toughened safety glass – Performance under accidental human impact

The thermally toughened safety glass has to be classified according to EN 12600; for its pendulum impact performance. This product can be used in critical locations (see BS 6262-4:2005)
