Ordering double glazed sealed units for jobs in County Durham
Toughened panes in a unit carry a permanent BS EN 12150 mark. Ask if you need units labelled by window number so the installer can match each unit to its frame.
Overall thickness has to match the frame rebate. A 28mm unit will not go into a frame glazed for 24mm, so check before you order.

Delivery across County Durham
We deliver to sites and yards in County Durham as part of our mainland delivery service. Delivery is priced on the quote, so you know the full cost before you place the order.
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.
