Composite doors combine a solid timber core, GRP outer skin and high-density polyurethane foam insulation — making them stronger, more secure and more energy-efficient than any single-material door.

Durham's UNESCO World Heritage cathedral and castle dominate the city's conservation profile — listed-building secondary glazing and heritage timber sash restoration are core work across the DH1 peninsula. We also serve the wider university-driven residential market with modern double glazing.
For doors and glass extensions in Durham, residential property style typically drives the design brief across North East — whether that's contemporary aluminium bifolds spanning a garden-facing rear elevation, slim-frame sliding doors that maximise glass area on a modern extension, or heritage French doors fitted to a period façade. Most commonly we're working in DH1 postcodes. Typical lead time from survey to install: 4-6 weeks for standard configurations, 8-10 weeks for bespoke or large-span builds.
