Ordering triple glazed units for jobs in Cornwall
Heavier units may need different hinges or rollers in opening sashes and doors. Check with the frame supplier if you are reglazing existing frames.
Triple glazed units are thicker and heavier than double glazed units, so the frame must be designed to take them.

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.

How do I get trade prices for Cornwall?
Send your schedule through the quote form or by email, and apply for a trade account if you do not already have one.
Is triple glazing worth it?
It lowers heat loss through the glass and can help with noise. Whether it is worth the extra cost depends on the property and the frames.
Can I put triple glazing in my existing windows?
Only if the frames have a deep enough rebate and hardware rated for the extra weight. Most older frames do not.
