Heat strenghtened glass is mainly used for curtain walls and exterior windows. Due to its slight image distortion, heat strengthened glass is often made into tempered coated glass for curtain walls and exterior windows.
Heat strengthened glass has a low risk of self explosion and good flatness, it has high strength and will not break to sharp fragments when breaking.
HS glass is different from tempered glass,heat strengthened glass cooling process is much slower . it has below Features:
Two times strength high than float glass, around half of tempered glass.
Radial shards after breaking,but can keep glass integrity.
No spontaneous breakage.
The flatness is better than tempered glass, better for the curtain wall or building facade to avoid the image deformation.
| TEMPERED GLASS VS HEAT STRENGTHENED GLASS | ||
| Tempered Glass | Heat Strengthened Glass | |
| Safety | Broken to small particles after breaking, will not bring serious harm. | Broken to bigger fragment and most of the glass still remains in the frame. It with high risk that harm people if it falls off. |
| Strength | More than 2 times that of float annealed glass | More than 4 times that of float annealed glass |
| Thermal stability | Higher than heat strengthened glass | Twice higher than that of the float annealed glass |
| Reprocessing | Can not be reprocessing | Can not be reprocessing |
| Self-explosion | Around 3‰ rate of self explosion | Around 1‰ rate of self explosion ,lower than tempered glass |
| Flatness | Tempered glass has the optical distortion. the bow bends should not exceed 0.3%, and wave bends not exceed 0.2% | With better flatness, easier for soft coating |
| Clear,Low Iorn,Tinted,Coated | |
| Glass Thcikness | Tempered: 3-19mm, Heat Strengthened: 4-12mm |
| Glass Standard | EN12150, ANSI2208,ASTM C1048,GBT15763.4,GBT15763.2GBT17841, 5 years warranty |
| Glass Size | MIN 300*300MM, MAX 13000*3000MM |
| Monthly Output | 50,000SQM |
