Pilkington Toughened Glass is up to five times stronger than ordinary glass of the same thickness. Because of its increased strength, Pilkington Toughened Glass allows architects and builders far greater scope in their use of glass in buildings. It meets worldwide safety standards for glass subjected to accidental human impact at the highest level of severity. Wherever the benefits of ordinary glass need to be combined with extra strength, safety or heat resistance, Pilkington Toughened Glass can offer a complete and proven solution.
Pilkington Toughened Glass (HS) is the heat soaked form of Pilkington Toughened Glass for those applications where a reduction in spontaneous fracture is advantageous, such as structural applications, barriers and roof glazing. In this case Pilkington Toughened Glass (HS) should be specified along with the other product benefits required.
Pilkington Toughened Safety Glass is manufactured by subjecting final size, edgeworked panes of glass to a heating and cooling treatment whereby high compressive stresses are set up at the surfaces with balancing tensile stresses in the centre. The high compressive surface stresses give the Pilkington Toughened Glass its increased strength.
