What is Toughened Glass?

Toughened glass is often referred to as safety glass or tempered glass. It starts as annealed glass that is heated and then rapidly cooled. It’s classed as a Grade A Safety Glass.

After going through the toughening process it becomes five times stronger than standard annealed glass of the same thickness. The toughening process also reduces the risk of cracking.

Toughened glass, when damaged, will shatter into tiny pieces so that anyone standing nearby will not be badly injured.

When it does shatter, be mindful when cleaning up that in some instances the glass can travel a number of meters in all directions.

Toughened glass is recommended in areas where windows require structural strength and safety such as elevation windows and large feature windows. Like laminated glass, toughened glass is also suited to areas of the home most prone to injury from human impact such as bathrooms, splashbacks, doors and full-length windows.

Toughened glass cannot be reused or re-cut once installed, something to consider if you want to have a pet door later. Alternatively, you can have the pet door installed prior to the glass going through the toughening process.

Advantages of Toughened Glass

  • Suitable for when strength, thermal resistance, and safety are all important considerations
  • Safer – if broken, the glass shatters rather than breaking into dangerous shards
  • Physically and thermally stronger than regular glass
  • Suitable for use in large openings
  • Available in different tones and opaque options

Disadvantages of Toughened Glass

  • Low E Toughened Glass option is not recommended for solar control when the winter sun provides natural heating
  • Sometimes exhibits minor distortion

Safety glass is a product that is designed to cause minimal injury when it breaks, compared to regular annealed glass. The two most commonly used safety glass products are laminated glass and toughened/tempered glass. Both products have very different and distinct features that provide various levels of safety and security.

Yes, however, the entire panel of glass will usually need to be replaced. We recommend replacing these panels with toughened glass as the hole required for the pet door makes the glass weak. Toughened glass alleviates this issue.

Laminated glass is two pieces of glass laminated together with an interlayer. When it breaks, it cracks but holds together, like a windscreen. Toughened glass is just one panel, but has undergone a process to make it 4-5 times stronger than normal glass. When it breaks, it shatters into thousands of small pieces the size of a fingernail.

Sometimes toughened glass will shatter instantaneously, without an apparent reason. This is often due to a small flaw within the glass itself from manufacture. If the flaw is present, the glass failure could happen at any time.

In the case of a glass emergency, we will attend the same day and can usually complete the repair on the first visit.

We can offer a range of different options to reduce outside noise entering your home. There are specific glass products available now that are designed for noise reduction that will significantly reduce noise without the need to completely replace the windows

We can offer a range of different options to reduce heat entering the home. We offer tinting services, but can also provide options for a high performance glass product specifically designed to reduce the heat entering the home.

Yes, we are an industry leader in the areas of accreditation, qualified tradespeople and safety. We are a founding member of the Australian Glass & Window Association national accreditation program and are active in the glass, glazing & window industry member forums and training programs.
