TOUGHENED SAFETY GLASS

The standards for Toughened Safety Glass are set out by the British Standards Institute, currently the standard is BS 6206, but this is in the process of being changed to, BS EN 12600 in UK Building Regulations.

Toughened glass has to be difficult to penetrate, and if broken, disintegrate into hundreds of small, relatively harmless pieces without sharp edges. It must also be resilient to fire.

Toughened glass is the most widely specified safety glass in conservatory building; it is made by applying a special treatment to ordinary float glass after it has been cut to the size needed for your conservatory. So you must allow time for this in the production timetable. The treatment involves heating the glass to approx. 620 degrees C so that it begins to soften and then rapidly cooled.

SECURITY ISSUES

Toughened safety glass is especially effective if it is double–glazed. The extra pane of glass greatly strengthens the window making break-ins more difficult to undertake and thus acts as a deterrent.
