Toughened safety glass

Listing ID #3508627

Tempered glass is being used increasingly in architecture because of its strength and safety properties. It is usually installed in areas where safety glass is required to lessen the possibility of mechanical or thermal breakage and or to assure greater uniform load strength. Glass is tempered by taking annealed glass and heating it to its softening point of approximately 660 C. its surface is then rapidly cooled while the inner core is allowed to cool gradually. This results in layers of high compression on the surface counter balancing by high tension at the center resulting in a glass that is four to five times stronger than annealed glass. Should accidental breakage occur, the resulting fragments are small and granular, causing minimum injury.
