Key Specifications/Special Features:
Tempered (toughened) glass is two or more times stronger than annealed glass
When broken, it shatters into many small fragments which prevent major injuries
This type of glass is intended for glass facades, sliding doors, building entrances, bath and shower enclosures and other uses requiring superior strength and safety properties
Two different methods used to produce tempered glass:
Heat treating:
Where the annealed glass is subjected to a special heat-treatment in which it is heated to about 680° C and afterwards cooled
If it is cooled rapidly, the glass is up to four times stronger then annealed glass and its breaks into many small fragments (fully-tempered)
If it is cooled slowly, the glass is twice as strong as annealed glass and the fragments of the broken glass are linear and more likely to remain in the frame
Chemical strengthening:
Glass is covered by a chemical solution which produces a higher mechanical resistance
Chemically-strengthened glass has similar properties to thermal-treated glass
Product is not generally used for window glass, but more commonly seen in industries where thin, strong glass is needed

Why Tempered Glass is Safety Glass
Tempered glass is used in applications where standard glass could pose a potential danger, because it is four to five times stronger than standard glass and does not shatter into large shards when broken. Manufactured through a process of extreme heating and rapid cooling, tempered glass is significantly harder than normal glass.
The brittle nature of tempered glass causes it to shatter into small oval-shaped pebbles when broken. This eliminates the danger of sharp edges. Due to this property - Along with its strength - Tempered glass is often referred to as 'safety glass. '
The thermal process that cures tempered glass also makes it heat-resistant. Tempered glass can be used in any situation where there is a danger of the glass breaking due to impact or extreme heat.
Here at Dulles Glass and Mirror, we have the capability of tempering glass in many thicknesses and sizes, thanks to our state-of-the-art fabrication facilities and tempering furnace, giving us the flexibility and speed that our customers have come to expect at factory-direct pricing.
Tempered Glass
Stronger Tempered glass is 5-8x as impact resistant as ordinary glass, with bending strength 4-5x as powerful. Tempered glass can stand higher static pressure loads than regular glass.
Thermally Stable (Less Heat Sensitive): Thermal stability is the property that allows glass to resist temperature differences. It is measured by the temperature difference that would cause the glass to crack. The thermal stability of tempered glass is 1.5-2x better than annealed (regular) glass. This means that while annealed glass would crack at 100 degrees Celsius, tempered glass can withstand temperatures of up to 320 degrees Celsius before cracking. It's this quality that makes tempered glass perfect for the outdoor heat.
Safer Tempered glass has many applications because of its safety characteristics. The safety of tempered glass comes from strength and its unique fracture pattern. When tempered glass breaks, it breaks into small, relatively harmless blunt glass fragments. This is called "dicing, " and reduces the likelihood of injury since there are no dangerous jagged edges or sharp shards.
