SPECIFYING OVERHEAD GLAZING
SPECIFYING OVERHEAD GLAZING
Paul Smith, Technical Chair of The Rooflight Association, explains why specifiers should consider laminated glass as the default inner pane when specifying rooflights as part of a robust approach to design risk management.
Aspontaneous explosion of heat soak tested toughened glass, while statistically rare, still represents a risk, one that designers should be aware of at specification stage. As the voice of the UK’s rooflight industry, it’s our duty to minimise this risk through education and promoting good practice. This is why we are recommending that laminated glass should be specified as the first choice inner pane for rooflights, unless a stringent risk assessment shows that a toughened inner pane does not introduce additional risk.
