Every day people see glass in storefronts, car windows, and even when they look in the mirror. But it’s not often you think about how different uses and products require various types of this material. Tempered glass is just one version that you likely come into contact with each day. Here’s a guide to understanding how it’s made and what it’s used for so you can select the right variety for your next project.

Tempered Glass 101

What Is Tempered Glass?

Regular home windows typically feature annealed glass that has been heated and then cooled slowly. For situations when this material isn’t strong enough, people opt for tempered glass, which is around four times more durable.

This glass is made from annealed glass that has been shaped, washed, and heated to over 1,112 degrees Fahrenheit. Then it’s quenched, a process where the material cools quickly because of exposure to quick puffs of cold air. The glass layers cool at different times, making the inside pull the outer layers away and creating pressure that strengthens the material. 

Instead of shattering into shards that are jagged and sharp like annealed glass, tempered versions come apart into many tiny pieces that are much less dangerous to touch. This is why the material has earned the nickname “safety glass.”

How Is It Used?

Because of the way tempered glass breaks, it’s considered safer in unique environments where humans come into close contact with glass. For example, sports courts often use it for areas where spectators want to see the action up close since it will be far less likely to harm players and audience members if it breaks. This glass is also used in vehicle windshields, patio doors, shower doors, and as patio tabletops. Home appliances like microwaves and ovens may also feature this material because it can withstand heat. Many banks and emergency facilities also feature this glass because it can protect staff from intruders.
