- Tempered glass is produced by heating annealed glass in a furnace to 620 degree centigrade.  Progressing from the furnace, the glass is rapidly cooled with jets of cold air, inducing compressive stresses to the surface while the center remains tensile. 

- It is 5 times stronger than annealed glass of the same thickness. 
- Stronger resistance to thermal breakage than annealed or heat strengthened glass 
- If breakage occurs the glass breaks up into small, cubical fragments, which are not threatening to humans. 

Thickness:
4mm,5mm,5.5mm,6mm 
8mm,10mm,12mm,15mm,19mm etc.
