  • 70mm solid timber and PU foam core construction
  • GRP skin in woodgrain or smooth finish

Made in the UK, fitted nationwide

Composite Doors from Arch-Door are manufactured in our West Midlands workshop and installed by our own fitting teams across England, Scotland, Wales and Northern Ireland. For supply-only orders we ship throughout the UK, with detailed fitting drawings supplied for your installer.

Built to last

Where it makes sense for the door type, we use engineered cores wrapped in solid timber lippings. This combination stops doors twisting and bowing — a common failure mode in solid-timber doors under British weather. Traditional mortise-and-tenon joinery handles the structural connections.

Finishes

Doors can be supplied unfinished, primed, painted, stained, oiled or factory-spray-finished. We hold a full RAL chart and standard timber stain swatches; bespoke colours matched on request.

Most enquiries get a quote within one working day. For larger projects we'll arrange a site visit before pricing.

Project types we cover

Composite Doors are specified for a wide range of project types: residential refurbishments, new-build housing, listed building work, commercial fit-outs, hospitality and high-end residential. Whatever the application, we'll tailor the specification — fire rating, security rating, acoustic performance, thermal performance — to suit.
