It is important to specify the right glass for the right situation on all projects. If you have any doub’t then please speak to a Professional body that can help or contact the Glass & Glazing Federation for advice too.
Our understanding is as follows;
Up to 5 metre’s internal height then toughened or laminated glass can be used. Toughened should only be considered if no other product is available.
If the internal height is between 5 & 13 metre’s then the glass thickness (if it is toughened) cannot be greater than 6 mm thick and up to 3m² in size.
Over 13metre’s, toughened glass, as an internal pane, can’t be used.
