Heritage Aluminium French Doors

Here at Colin’s Sash Windows our second biggest selling product is steel replacement aluminium exterior 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. The Heritage door is 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.

Heritage door profiles feature the system’s signature slim sightlines and elegant lines that mimic those of steel doors. The system has all the advantages of modern aluminium profiles that feature polyamide thermal breaks, allowing the system to achieve a U Value of 1.5 W/m2k when installed with a suitable sealed unit.

Steel look doors and windows

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.
