Art Deco-inspired aluminium heritage doors
Our exclusive range of Art Deco-inspired heritage doors with narrow mid-rails provides a traditional style for almost any project or property type.
Manufactured from the highest quality thermally broken aluminium to meet the requirements of Building Regulations Document L, our heritage doors match the industrial appearance of traditional forged steel doors with the contemporary thermal and weather performance standards.
Available as single doors, French doors, bifold doors, sliding doors and windows, the steel look style is one of the fastest growing trends in glazing design. The slender frames of the SUNFLEX UK range of systems allow for the addition of narrow mid-rails whilst still maximising the amount of glass.
Every SUNFLEX UK heritage door is custom made to order in our own factory, ensuring the quality and performance you would expect of a SUNFLEX UK system.

Heritage French Doors
With narrow, thermally broken aluminium frames, our heritage doors are ideally suited to replacing traditional steel doors as single or French doors for either internal or external purposes.
They can be combined with sidelight windows alongside the doors for larger openings. Ideal for replacing steel doors and windows whilst maintaining the same aesthetic design.
-
Heritage Sliding Doors
Utilising our advanced SVG20 or SVG30 sliding door technology, our heritage sliding doors are ideal for large openings because of their ability to incorporate glass panels up to 2000mm wide.
The system can be configured in a wide range of ways, including sliding into a pocket or incorporating a moveable corner post to create a completely open corner.
-
Heritage Bifold Doors
Based on more than 35 years of folding door experience, our heritage bifold doors make use of the outstanding performance, incredibly narrow frame depths and slim sightlines of the SUNFLEX SF55i bifold door.
Our heritage bifold doors combine the much sought after appearance of the traditional steel doors, with the ability to stack the panels completely to one end to create an unobstructed opening.
