Versatile And Striking Traditional Aesthetics

Heritage aluminium doors offer a bold, elegant way to define or divide spaces. Slim profiles maximise natural light while maintaining the character of period homes and the clean lines of modern interiors. These robust aluminium frames can be used for rear extensions, internal partitions, shower screens, and more.

With the full RAL colour range available—including timeless black and refined Anthracite Grey—each design is tailored to suit your property. Heritage aluminium doors provide the visual appeal of steel with the benefits of low maintenance, thermal efficiency, and long-lasting performance.

Security, Durability and Thermal Efficiency

All doors are constructed using high-strength aluminium and fitted with multi-point locking. Thermal break technology and double-glazed units deliver improved energy performance, reducing heat loss and improving comfort year-round.

Our doors are FSA-approved and fully recyclable. They outperform timber and uPVC alternatives in both lifespan and structural strength — making them a smart long-term investment.
