Heat Strengthened Glass
15mm Heat Strengthened Glass
Heat Strengthened Glass for laminated glass
Heat-strengthened glass differs from tempered glass in surface compression; its mechanical strength is about 1.6-2 times that of annealed glass.

Features
1. Heat-strengthened glass differs from tempered glass in surface compression; its mechanical strength is about 1.6-2 times that of annealed glass.
2. Heat-strengthened glass has outstanding thermal stability, its flatness and light transmission is close to that of annealed glass and much better than that of tempered glass.
3. HS Glass is 3 times more resistant to thermal stress in comparison to normal annealed glass.
4. It can withstand temperature difference of 100°C (in range of 50°C to 150°C) compared to ordinary annealed glass which can withstand up to 40°C.
5. Heat strengthened glass is that it is far less susceptible to spontaneous breakage.
Application
Heat-strengthened glass is widely used in laminated glass for additional strength, such as in overhead and sloped glazing.
