Collection: Composite Doors

Browse our range of premium composite doors supplied and fitted across Bedfordshire, Hertfordshire, and Buckinghamshire. Composite doors combine a solid timber core with a tough GRP (glass reinforced plastic) outer skin, giving you the look of a traditional timber door with far superior strength, security, and thermal performance.

Available in a wide range of colours, styles, and glazing options — including popular shades like Chartwell Green, Anthracite Grey, and Slate Blue — our composite doors are built to last and backed by a 10-year manufacturer's guarantee.
