Toughened and/or tempered glass are types of safety glass with increased strength both physically and thermally.

To increase its strength compared with normal glass. Tempering creates balanced internal stresses which cause the glass, when broken, to crumble into small granular chunks (Called dice) instead of splintering into jagged shards. These granular chunks are less likely to cause injury as they do not have sharp edges and dagger points of normal broken glass.

Toughened glass is used when strength, thermal resistance and safety are important considerations.

It is used mainly in buildings for unframed assemblies (such as frameless doors), structurally-loaded applications, and any other application that would become dangerous in the event of human impact.

Toughened glass must be cut to size and have all processing such as drilling, Polishing etc. completed before the thermal process, any attempt to cut the glass afterwards will result in it shattering, therefore no refunds can be made.

All installed safety glass should be marked with the British standard test Ref: BS6206. Accompanied by the letter L for laminated and T for Toughened, along with the company registration number of the Supplier.
