Residential Heritage Aluminium Doors & Windows
Bring timeless elegance into your home with Alitherm Heritage aluminium systems — the perfect solution for homeowners who want to preserve classic character while enjoying modern comfort, energy efficiency, and security.
A modern thermal aluminium solution for both heritage and refurbishment projects where the requirement to replace old steel windows is essential.
Alitherm Heritage provides an ideal solution for heritage applications such as listed building renovations and large-scale refurbishment projects where planning constraints are to be considered. The window is designed to be built as a series of horizontal modules which can be stacked using horizontal couplers to form a multi-part window, featuring a specially designed drip bar between modules.
Alitherm Heritage profiles utilise Smart’s innovative polyamide thermal break technology which creates a barrier between the cold air outside and the warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U Value of a product and is designed to meet the exacting requirements of Document L 2010.
Alitherm Heritage products are available in a choice of standard or non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodised effect finishes.

Why Choose Heritage Doors for Your Home?
Heritage aluminium doors are designed specifically for residential properties where the look of traditional steel windows is important, but performance and comfort cannot be compromised. Whether you are upgrading a listed townhouse, renovating a family home, or adding period charm to a modern property, Alitherm Heritage offers the best of both worlds.
Unlike standard doors, these systems replicate the slim sightlines and historic proportions of traditional steel, giving your home authenticity and style. At the same time, they incorporate advanced polyamide thermal break technology, which forms a barrier between cold outside air and warm indoor comfort. This dramatically reduces heat transfer, improves U-values in line with Document L 2010, and lowers your energy bills.
Every residential installation is fully tailored — from size and glazing to finish and hardware. Choose from a wide range of colours, including metallic and dual tones, or opt for textured and anodised effects that enhance the individuality of your property. With weather-tested durability and PAS 24-certified security, you can be confident your home remains safe, comfortable, and stylish for years to come.
Heritage aluminium systems are also modular, meaning they can be installed as single doors, casement windows, or as stacked multi-part assemblies using horizontal couplers. This flexibility makes them ideal for residential projects where both design integrity and practicality matter.
