Characteristics - Temper Glass
● Tempered glass is approximately five times stronger than annealed glass
of equal thickness
● Tempered glass has greater resistance to thermally-induced stress than heat-strengthened
or annealed glass
● Suitable for use as a safety glass
● Tempered glass is also mandated
in other parts of the world by individual country regulations or specifications
Applications - Temper Glass
● Suitable where safety glazing is required
● Fire knock-out panels
All glass entrances and storefronts
● Extreme wind loads
Manufacturing - Temper Glass
1. The heating process places the surface of the glass in a
state of compression and the core in a state of compensating tension.
2. The annealed glass is placed on a conveyor. The glass is
heated to approximately 1150 degrees Fahrenheit.
3. Rapid Cool: the glass is cooled (quenched) by the application
of high pressure air.
