Independent Glass Heat Strengthened glass is manufactured to BS EN1863.

Heat strengthened glass is designed to give some of the characteristics of toughened glass e.g. a proportion of the increased strength ( approx 1.5 times stronger than annealed) and thermal resistance ( approx. twice as resistant to thermal stress and shock than annealed) while retaining the fracture characteristics of annealed glass.

Heat strengthened glass should not be considered a safety glass in its monolithic form but it can be laminated.

Independent Glass offer Heat Strengthened glass in its monolithic form for building applications requiring resistance to thermal stresses but can also supply laminated Heat Strengthened glass which then combines the thermal stress resistance characteristics with safety performance to the relevant BS EN 12600 classification.
