Tempered glass is one kind of high-strength glass with even compressive stress on the surface which is made by heating float glass to nearly softening point and then cooling it down rapidly by air.

1.Times harder than ordinary float glass, stronger resistance to thermal breakage than annealed or heat strengthened glass.

2.Once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to human body.

3.It withstands abrupt temperature change of 220 Centigrade.

Tempered offline low-e glass is safety glass, which is widely used as window glass, door glass, curtain wall glass, fencing glass in buildings, hotels, etc
