Composite doors are constructed from multiple materials working together: a solid or engineered timber core, a dense polyurethane foam insulation layer and a glass-reinforced plastic (GRP) outer skin. The result is a door that won’t warp, rot, crack or fade – even through years of British weather.
Unlike timber doors, there’s no sanding, sealing or repainting required. A simple wipe-down is all it takes to keep your composite door looking as good as the day it was fitted – freeing up your weekends and protecting your investment long-term.
Malbern Windows has been fitting doors and windows across the region since 1983. That depth of experience means every composite door we install is measured precisely, fitted correctly and sealed properly – so you get the full performance the door is designed to deliver.
A poorly installed door, regardless of quality, will underperform. Our experienced fitters take pride in getting every detail right, from squaring the frame to checking the seal, ensuring your new door performs exactly as it should for decades to come.

Absolutely. Composite doors are available in a wide range of colours, finishes and glazing styles. Dual-colour options - different inside and out - are also available for a fully bespoke look.
Yes. The insulated core and draught-proof seals help reduce heat loss through your doorway, improving your home's overall thermal performance and supporting lower heating costs.
