Toughened Glass? Not So Tough

At Warrior Doors we have recently had a number of enquiries to fit Toughened Glass in our Communal Entrance Doors.

Due to the name, it is not unreasonable to assume that Toughened Glass is secure. However, toughened in this case does not mean the product is necessarily capable of withstanding an attack or impact.

Toughening is a thermal process that changes the surface of the glass, as a result making it brittle and fragile.

Additionally, it is prone to fail easily from even a light impact under certain conditions e.g. from a sharp object.

Furthermore, the main purpose of toughening is to break the glass upon impact into chunks less likely to lead to injury. However, the fact that it easily breaks means it is not a secure solution.

At Warrior Doors we fit only LPS 1270, and laminated anti-bandit glazing in our products. The laminated glazing that we fit contains a layer of PVB (polyvinyl butyral). Additionally, the LPS 1270 certified glazing we use  layers of PVB in addition to layers of polycarbonate and glass.

To conclude, the minimum security level glazing product we use is 11.5mm anti-bandit glass. We choose to use this for residential buildings which feature communal entrances. Laminated anti-bandit glazing is much more impact resistant and appropriate solution for a security door or screen than Toughened Glass.
