The Alitherm Heritage ranges specifically designed to meet the requirements of refurbishment and renewal projects. Ideal for Victorian and Art Deco projects, the range of commercial and residential windows and balcony doors are already proven in a wide range of renovation, refurbishment and heritage projects across the UK.

The Alitherm Heritage door and window ranges not only feature the slim profiles and sight lines that are associated with traditional steel doors and windows but also provide a ‘B’ Energy Rating to improve thermal efficiency. Featuring slim, thermally-broken profiles, Alitherm Heritage windows are available in a number of formats, including fixed-pane, sash, top- and side-hung casement, pivot and tilt and turn. These different options may be installed in a combination of horizontal modules, which are stacked using our coupling options to form a multi-part window.

Available in both single and double door applications, Alitherm Heritage doors are available in a wide range of sizes and are supplied with a traditional single point lock mechanism as well as face-mounted locking bolts. Both the window and door systems deliver a U-Value of 1.5, when installed with a suitable sealed unit, and are available in either single or dual polyester powder coated finishes.

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, which for a typical terraced house would provide a saving of around £95 each year in fuel costs. In addition to these energy savings, 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.

The Alitherm Heritage ranges are all available with a full suite of hardware options, with products specifically designed to match the door and window furniture that is synonymous with Victorian and Art Deco styles.

Both the window and door systems, and accompanying hardware and accessories may be supplied in any colour from our extensive Naturals, Sensations and RAL ranges, as well as Smart’s Alchemy range. Alchemy offers eight anodised colour matches, including shades of gold, bronze, silver, grey and black, and combines the unique style and aesthetics of traditional anodising, with the advantages of a high quality powder coating process.
