Toughened Glass
Toughened or tempered glass is produced when float glass panels are heated and then cooled rapidly in a controlled environment. This process makes the glass several times stronger than regular glass. It also makes it safer because when broken it yields small pebble-like fragments.
Our range of toughened glass glass is known for high strength and superior safety. Due to such properties, toughened glass glass is widely used in building construction and most popular among architects.

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)

Selection Criteria for Tempered Glass

Tempered glass is known for strength and safety, which makes it suitable for various glazing applications. Widely used in various applications, this is rated as a safety glass in different international standards.

Some of the applications of the tempered glass are:
When glass strength is needed:

1. In point fixed glazing as well as bolted and patch fittings
2. For buildings in windy areas
3. Where the risk of impact breakage is more
4. Where the risk of thermal breakage is high

When glass safety is needed:
1. In facades of higher buildings or skyscrapes,
2. Where there is a risk of falling glasses
3. 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.
