Measuring tip
Check the frame rebate takes the overall unit thickness before you order; most older frames are not deep enough for triple glazing.
Regulations for jobs in Harpenden
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.
