Trade double glazed sealed units in Greater London

Ordering double glazed sealed units for jobs in Greater London

Glass in critical locations, such as doors, side panels and low-level glazing, must break safely, be robust or be protected; in practice that usually means toughened or laminated glass. Mark those units on your schedule.

Sealed units are made to the exact glass size, so the measurement is the size of the unit itself. When replacing a misted unit, measure the old unit once the beads are off.

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.

Every order is confirmed in writing first. The acknowledgement lists each item exactly as it will be made, so any mistake in a size or handing can be caught before manufacture.
