Tempered Glass Windows | FAQ

Windows that have the potential for human impact are legally required to contain tempered glass. Also known as toughened glass, tempered glass is stronger and safer than regular glass. The tempering process changes the properties of the glass, so that if it should be broken, it crumbles into dull cubes to minimize any injury.

Frequently Asked Questions About Tempered Glass Windows

Here are some of the questions we’ve answered for our customers about the value of safety glass.

Q. When is a window required to be made from tempered glass?

According to the National Glass Association, there are 4 criteria that require safety glass:

  • The glazing (glass) is less than 18 inches above the floor
  • The top of the glass is less than 36 inches above the floor
  • The size of the glass exceeds 9 square feet
  • The glass is within 36 inches of where people walk

Don’t worry, our glass experts will make sure your windows are up to code. Any door made of glass — sliding, French, or shower doors — are all always made of tempered glass.

Q. If tempered glass is so tough, why do I have to worry about the window getting broken?

Toughened glass is one thing, but unbreakable glass is something entirely different. Tempered glass is stronger than standard (annealed) glass and in the event of breakage, it will produce dull cubes as opposed to sharp, jagged pieces.

Q. Can you cut tempered glass to size?

No, but what we do is cut the glass before it’s tempered. The glass is subjected to intense heat and rapid cooling that tempers it. Once the glass is tempered, you can’t modify it or it will break.
