What is Toughened Glass?

Toughened glass or tempered glass is treated to be far more resistant to breakage than simple annealed glass and is up to five times as strong as ordinary glass which means that it has to be hit much harder in order to break. Also when it does break it is into lots of small pieces which are much less dangerous instead of splintering into large shards as plate glass, thus providing a major safety advantage in all of its applications.

Toughened glass is made from annealed glass treated with a thermal tempering process. A sheet of annealed glass is heated to above its “annealing point” of 600°C. Its surfaces are then rapidly cooled while the inner portion of the glass remains hotter. The different cooling rates between the surface and the inside of the glass produces different physical properties, resulting in compressive stresses in the surface balanced by tensile stresses in the body of the glass.

These counteracting stresses give toughened glass its increased strength. Toughened glass is physically and thermally stronger than regular glass. Any cutting or grinding must be done prior to tempering. Cutting, grinding, and sharp impacts after tempering will cause the glass to fracture.

Toughened glass has extremely broad applications in products because of its safety and strength. As a result it is used in a number of demanding applications, including windows, glass shower doors, architectural glass, sliding glass doors, glass tables, glass balconies, glass office partitions, kitchen glass splashbacks, glass balustrades, walk on glass and many other applications.

Great service from the team. Easy to order, good buying guidance and clear install instructions for my builder. Rooflights look absolutely great! The team at TGS couldn't have been more helpful in organising a smaller delivery vehicle to help with restricted access. Highly recommend TGS.

The glass balustrade gives us an amazing view onto the lake outside. So happy we ended up going for the frameless glass balcony from Toughened Glass Systems instead of one with posts

My job is to design the interiors for a lot of houses and a lot of times the hardest part was when the client wanted some really inexpensive rooflights that should look like some contemporary ones as well. That until I found Toughened Glass Systems and started working with them more and more. They have a lot of this kind of stuff at a very decent price, a price for anyone I can say. If you’re looking for cheap skylights for flat roofs or any types of roof lights, they probably have something for you.
