12mm Toughened Glass

12 mm Toughened Glass is manufactured by subjecting cut to size 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.Toughened glass is four to five times stronger than annealed glass of the same size and thickness against impact. Toughened glass has higher thermal strength and can withstand a high temperature differential up to 250°C.Toughened or Tempered Glass (both are same) is a term for a safety glass which is strengthened due to controlled thermal heating in the furnace after which the plain glass gets five times stronger without losing any transparency.Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension.
