TOUGHENED GLASS
The salient features of our range includes
1. 4-5 times stronger than annealed (raw) glass of same thickness
2. Can resist thermal stresses as edge strength is higher
3. Breaks into small blunt pieces providing safety (full tempered glass is a safety glass).
Some of the applications of the tempered glass are
When glass strength is needed
- In point fixed glazing as well as bolted and patch fittings
- For buildings in windy areas
- Where the risk of impact breakage is more
- Where the risk of thermal breakage is high
When glass safety is needed
- In facades of higher buildings or skyscrapes,
- Where there is a risk of falling glasses
- Where there is a possibility of human contact e.g. facade, skylights, fittings interiors, table tops, shelves, etc
Toughened Glass Properties
| Properties | Tempered Glass |
| Thermal Shock Resistance | Up to 250°C |
| Mechanical Strength | 4 to 5 times stronger than annealed glass |
| Tensile Strength | 65 Mpa |
| Bending Strength | 120-200 N/mm2 |
| Surface Compression | 95 Mpa |
| Design Stress for Architectural Purposes | 50 Mpa |
| Fragmentation | Small round crystals |
| Conducive for Processing | Cannot be cut after Tempering |
Tempering increases tensile strength, thermal shock resistance, and safety of normal glass. It also increases its heat with standing capacity. Because of these properties, tempered glass is preferred in applications where strength, safety and thermal resistance are important considerations.
