Trade triple glazed units in Cheshire

Ordering triple glazed units for jobs in Cheshire

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.

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.

Before anything goes into production you get a written order acknowledgement with sizes, finishes and handing for every item. Check it carefully, because made-to-measure items cannot be returned if the sizes were wrong.
