Pilkington Toughened Glass achieves up to Class 1(C)1 when tested to BS EN 12600 Class A impact performance to BS 6206. In general, the strength is up to five times that of annealed glass, but is to some extent dependent on glass type and thickness.

Pilkington Toughened Glass can withstand extremes of heat and cold and offers greatly increased resistance to sudden temperature changes compared with annealed glass. It can also be used in service within the temperature range from 250ºC down to sub-zero temperatures without affecting their performance and, unlike annealed glass, can withstand sudden shock temperatures of approximately 200ºC.
