Heritage external doors 1

Heritage doors are a timeless addition to any home, offering classic style and durability. Made from high-quality materials such as oak or mahogany, these doors are designed to last for generations. With intricate detailing and traditional craftsmanship, heritage doors are a beautiful and practical choice for any property.

Here at Colin’s Sash Windows our second biggest selling product is steel replacement aluminium exterior heritage doors. They’re so popular at the moment. The design comes from the Art Deco period last century but now they’re double glazed and energy efficient.

Heritage doors are the ideal replacement for steel balcony doors on heritage applications such as building renovations or apartment conversions. The industrial style door provides the solution for conservation areas where planning regulations require a like-for-like product replacement.

The doors are custom made, available in bespoke sizes. We also sell Alitherm Heritage windows so you can match doors and windows in your project.

We’ve chosen Smart Systems Alitherm Heritage doors profiles. These are the original and best aluminium steel-look heritage doors. They feature the system’s signature slim sightlines and elegant lines that mimic those of steel doors.

Alitherm Heritage has all the advantages of modern aluminium profiles that feature polyamide thermal breaks, allowing the system to achieve a U Value of 1.6 W/m2k – 1.8 W/m2k depending on glass to aluminium ratio.

Benefits of our steel look aluminium windows and doors

Alitherm Heritage provides a modern light-weight, high-strength and cost-effective alternative to traditional steel window and door systems, offering a wide range of benefits:

Increased Lifespan
Because aluminium does not rust or rot, window frames provide great longevity and can last indefinitely. This also means that the aluminium windows have the longest lifespan of any window framing material, with typical replacement periods of 40 years – compared to a typical 35 year replacement period for steel, PVC and timber.

Improved Thermal Efficiency
Modern aluminium windows are thermally-broken using polyamide, an excellent insulator which helps to insulate windows against heat loss. The thermal conductivity of polyamide is 160 times better than steel and the polyamide also raises the internal temperature of a house, helping to reduce the risk of condensation.

Reduced Maintenance
Maintenance for aluminium systems is simple and straightforward, with a routine ‘wipe-clean’ all that is required to keep the products looking their best. With no requirement for re-painting or re-varnishing, aluminium windows and doors will never fade, deteriorate or rust, even in harsh environments, such as coastal locations, where steel windows can be particularly prone to rust, requiring regular maintenance and eventually, replacement.

Why Choose our Steel Look Aluminium French Doors and Windows?

Firstly, our Heritage aluminium doors are much more cost effective than the steel alternatives and the frames are much slimmer than other aluminium, uPVC or timber doors allowing more light into the room. They really look amazing!

They comply with all current building regulations, importantly energy efficiency being double glazed with thermally broken frames. They are very secure with multi-point locking.

They’re available in any RAL colour with 10-year warranty. Our most popular colour is black matt to give the industrial black steel doors heritage look. Anthracite grey RAL7016 matt and gloss white are also standard.
