Controlled thermal treatments

Our toughened glass is processed by controlled thermal treatments which increase its strength. Before the glass is manufactured into sealed units, it goes through our toughening plant which quickly heats it up to 700 degrees.

The glass is then rapidly cooled down, changing its molecular structure and transforming it into a stronger product. When broken, toughened glass shatters into small pieces, which are considerably less likely to cause injury.

What Is The Difference Between Annealed And Toughened Glass?

Annealed glass is softer than toughened (also known as tempered) glass. It’s commonly used for tabletops and cabinet doors. Our toughened glass is five times harder than standard annealed glass, giving it greater shatter resistance.

Toughened glass is required in certain designated areas of a property (residential and commercial) to comply with building regulations.
