Ordering triple glazed units for jobs in County Durham

Triple glazed units are thicker and heavier than double glazed units, so the frame must be designed to take them.

A third pane lowers the U-value of the glass. How much of that reaches the whole window depends on the frame as well.

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.
