What is Toughened Safety Glass?
Toughened safety glass is float glass that has been put through the toughening process. This is where the glass is heated and cooled in a way that makes it 4 to 5 times stronger than regular annealed (float glass) of the same thickness.
This type of glass is considered Grade A Safety Glass according to the Australian Glass and Glazing Standards. This glass is more impact resistant than float glass, however, it is not resistant to breaking if impacted significantly enough. Standard Float glass breaks into large, sharp shards, which is quite dangerous. Whereas Toughened Glass breaks into tiny cuboid pieces, designed to minimise the risk of injury to people.
Where can I use Toughened Glass?
- Toughened glass must be used in either semi-frameless or framed shower screens as the glass edging is exposed.
- Safety glass must be used in wet areas such as bathrooms, and toughened glass is a great option for this. (Note – toughened glass is one type of safety glass that can be used).
- Toughened glass can be used indoors and for sidelights (glass panels next to doors).
- Sliding doors often have toughened glass in them too.
- We also recommend that toughened glass is used when installing doggy doors/pet doors in homes.
- Toughened glass must be used for glass tabletops, where the glass is supporting the weight of the items that will sit on top of it. For example, in outdoor table settings where the glass is surrounded by a frame.
- Unframed pool fencing and balustrading.
The Pros and Cons of Toughened Safety Glass
Benefits of Toughened Glass:
- Strength – as mentioned above, toughened glass is 4 to 5 times stronger than its float glass counterpart.
- Safety – toughened safety glass is harder to break than regular glass.
- Versatility – it can be used in a variety of different areas in a house such as in windows, doors, shower screens, fencing etc. as it meets the Australian Standards for Glass and Glazing.
- Aesthetically pleasing – This glass is able to be utilised in places to create great aesthetics and ambience. It offers a very modern and elegant aesthetic in homes when used in areas that do not have to have bulky frames around the glass.
The Cons of Toughened Glass:
- Toughened glass cannot be re-sized. Once it has been cut to size and toughened, it is permanent. You cannot cut it again as it will only break.
- Although it is stronger than regular glass, it can still break and when it does. It breaks into tiny pieces that can cause quite a mess.
- Spontaneous explosions… We often get asked if toughened glass can spontaneously explode. The answer is, sometimes it can… If there is uneven heating of the glass panel itself, or if the glass is pressed up against a frame, where the frame does not expand at the same rate as the glass, it can result in breakage/exploding.
- Cleaning up the glass when broken can be cumbersome, as the tiny pieces can travel quite a distance and also get stuck in the window framing/sliding door.
