Building regulations in England

Under Approved Document K, glazing in critical locations (doors, and side panels within 300mm of a door, up to 1500mm above floor level; other glazing below 800mm) must break safely, be robust or in small panes, or be permanently protected. Toughened and laminated safety glass are classified to BS EN 12600. Replacing only the glass in an existing frame is generally treated as a repair rather than notifiable work.

We do not start manufacturing until you have approved the order acknowledgement. It repeats each size, colour and opening direction so you can check it against your survey.
