How Safe is Finzone Frameless Glass?
Toughened glass and laminated glass are used to produce frameless glazing that is safe for most applications.
Toughened or tempered glass is made by heat-treating float glass in order to change its physical characteristics. This makes it much stronger than normal glass and also means it breaks more safely. Instead of shattering into sharp splinters, toughened glass crumbles into granular chunks, which is why it is used for car windows.
The main disadvantage of toughened glass is that it has to be cut to size and drilled before toughening takes place.
Laminated glass is made from sheets of glass sandwiched together. These are separated by a thin film of material such as polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). If it cracks, the film holds it together.
