Tempered Glass
Tempered Glass is essentially annealed glass that is heat-treated which makes it several times stronger than ordinary annealed glass. It is manufactured by heating up the float glass to a high temperature of about 650ºC, then blowing air onto its surface, cooling it down swiftly and uniformly.
Why use Tempered Glass
Tempered Glass is about four to five times stronger than annealed glass of the same thickness. This is due to contraction of the inner layer during the process of tempering hence inducing compressive stress on the surface of the glass.
When annealed glass breaks, the glass fractures into large, sharp shards. However, when tempered glass breaks, the tensile stress layer inside collapses, resulting in broken glass fragments to be small and relatively harmless compared to breaking of annealed glass.
Uses of Tempered Glass
• Atriums, partitions.
• Tub and shower enclosures.
• Sliding doors
• Squash court wall
Features
• On the same thickness Reliance Tempered Glass has bending and impact strength which is 3 to 5 times higher than that of ordinary glasses.
• As resistant to rapid temperature changes (thermal shocks), Reliance Tempered Glass is approximately 3 times better than ordinary float glasses.
• When broken, Reliance Tempered Glass will shatter into small pieces to prevent serious injuries.
Applications
• Frameless tempered glass doors
• Curtain walls
• Shop fronts
• Windows
• Showcase
• Escalator side plates
• Elevators panels
• Balustrades
