Pilkington Toughened Glass is manufactured by subjecting the final glass size to a heating and cooling treatment. A balance of high compressive stresses at the surface and tensile stresses in the centre of the glass increases its strength. The result is a glass that is 5 times stronger than ordinary glass of the same thickness.
The high compressive surface stresses give the glass its increased resistance to mechanical and thermal stresses. It can, however, break under extreme loads or by severe impact. When broken, toughened glass shatters into small, blunt-edged fragments, reducing the risk of personal injury. Up to 5 times stronger than ordinary glass of the same thickness, offering a proven solution to safety and strength concerns
