Toughened or tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass.


Toughened or tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering creates balanced internal stresses which cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards. The granular chunks are less likely to cause injury.

Fully tempered glass in the US is generally rated above 65 MPa (9427 psi) in pressure-resistance while heat strengthened glass is between 40 and 55 megapascals (5801 and 7977 psi respectively)

  • Tempered safety glass often does not fall out of its frame when it breaks - usually due to the anti-splinter film applied on the glass
  • The term toughened glass is generally used to describe fully tempered glass but is sometimes used to describe heat strengthened glass as both types undergo a thermal 'toughening' process.
  • There are two main types of heat treated glass: heat strengthened and fully tempered. Heat strengthened glass is twice as strong as annealed glass while fully tempered glass is typically four to six times the strength of annealed glass.
  • It is important to note that the tempering process does not change the stiffness of the glass. Annealed glass undergoes a similar deflection compared to tempered glass under the same load. But tempered glass can take a higher load and therefore deflects further before breaking.

Common Uses of Tempered Glass

Tempered glass is a one of the various types of safety glass present on the market and its use is to avoid potential danger when it breaks. The glass is passed from a thermal process that makes it heat resistant and adds more durability to the glass. Therefore, it's also called safety glass. This type of safety glass is used in many different areas of our lives. Here are 5 common uses for tempered glass:

1. Automotive Glass: Broken glass shards are a very serious health hazard and can even lead to death. Tempered glass is most commonly used in car windshields because of its special property of breaking into small, non-lethal pieces. With the high rate of traffic accidents happening each day, making use of tempered glass has led to fewer traffic fatalities. The introduction of tempered glass in automobiles was a turning point in safeguarding human life.

2. Monitor Screens: Another use of tempered glass is in computer monitors and laptop screens. You may not be likely to break the screen of a monitor or of your laptop, but accidents happen and it's better to be safe than sorry. Using safety glass in monitor screens is a very good idea. Another feature of safety glass, apart from durability, is that it is scratch free. Many mobile companies use tempered glass in mobile phones to make the product durable and scratch free.
When using frameless glass doors or sliding doors, tempered glass is used to ensure the maximum protection. Safety glass is typically used in the outside windows of many houses, especially the modern all glass façade house, because of its durability.

3. Construction: There are many laws and regulations when it comes to the use of glass, and many a times local laws prohibit the use of standard glass. Contractors have to make use of tempered glass. Safety glass can and is used practically everywhere in the house.

4. Home Appliances: When you need heat resistance and durability, tempered glass is used. Perhaps the most common appliance that uses tempered glass is the microwave oven. A microwave oven has to be able to sustain great amounts of heat. Tempered glass is an ideal asset for a microwave oven. It's also used in the traditional baking oven because like a microwave oven, it needs to keep up with high amounts of temperature.

5. Commercial Uses: Tempered glass is used to make phone booths, glass bus stops, escalators, stairways, solar panels and even in some sporting events. Many of these are places that we have regular access to. Therefore, the use of tempered glass is only limited by the creativity of the human mind.
