Laminated safety glass is often recommended for roof glazing although toughened glass is sufficient for some overhead glazing applications.
Toughened glass roof glazing.
This glass has all the benefits of toughened glass but without the risk of pieces of glass falling from the roof light if one or both of the sheets of glass in the laminate break.
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.
More or less without exception the outer pane of a double glazed unit should be toughened glass.
If the glass roof forms part of an accessible area it must be treated as a glass floor.

The inner pane may be toughened or laminated depending upon location and height above ground.
