Toughened glass roof glazing.

Toughened laminated glass is similar to annealed laminated glass but the sheets of glass that are laminated together have been toughened and heat soak tested. If the glass roof forms part of an accessible area it must be treated as a glass floor. Pilkington toughened glass ths is the heat soaked form of pilkington toughened glass for those applications where a reduction in spontaneous fracture is advantageous such as structural applications barriers and roof glazing.

If the glass roof forms part of an accessible area it must be treated as a glass floor.

The regulations allow the use of toughened glass overhead however if toughened glass is used as the lower pane then a safety glass must be used in the upper pane. The inner pane may be toughened or laminated depending upon location and height above ground. For double glazing the lower pane should be one of either pilkington optilam or pilkington pyroshield 2 and the upper pane need not be a safety glass.
