Trade composite doors in Northumberland

Ordering composite doors for jobs in Northumberland

For flats where the front door opens onto a common stair, the door may need to be fire-rated. Fire doors are a separate product and are not supplied as standard composite doors.

Side panels and toplights are made to match the door, so order them together. Separate orders can come from different batches and the colour can vary slightly.

Building regulations in England

Replacement external doors in England should meet a U-value of 1.4 W/m²K under Approved Document L. Glass in doors and side panels below 1500mm is a critical location under Approved Document K, so it must break safely (toughened or laminated to BS EN 12600), be robust or in small panes, or be permanently protected. Doors into new homes also need to meet Approved Document Q for security, which is usually shown with PAS 24. Replacing a door that is more than half glazed is notifiable building work, self-certified through a competent person scheme or approved by building control.

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.
