What is tempered glass or toughened glass? They are both the same thing and known as superior safety glass as it is 5 times tougher and can resist up to 500% more heat. There is an advantage to apply in timber or uPVC windows and doors as it can tolerate more stress, higher impact and endure extreme temperatures in high risk areas. It is the better choice to provide extra security than standard clear glass.
To achieve the benefits in toughened glazing, glaziers have to heat annealed glass to very hot temperatures reaching to 650°C and then rapidly cooling it down. This tempering process strengthens the structure of the pane and improves the thermal properties for higher heat resistance, better shock absorption and naturally increases toughness.
