Trade triple glazed units in Blackheath

Triple glazed units for Blackheath jobs

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

Heavier units may need different hinges or rollers in opening sashes and doors. Check with the frame supplier if you are reglazing existing frames.

• Three panes with two gas-filled cavities
• Warm-edge spacer bars
• Common overall thicknesses such as 36mm and 44mm
• Low-E coatings on the inner panes

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 Blackheath

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.
