Alitherm Heritage Doors - Aluminium Residential Door

Taking inspiration from traditional steel doors, Alitherm Heritage features signature slim sightlines and attractive aesthetic contours coupled with polyamide thermal

break technology giving Alitherm Heritage enhanced thermal performance and narrow sightlines.

Thermally broken, aluminium, single or double doors incorporating innovative polyamide thermal break technology, which creates a barrier between the cold air outside and warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U-value of the product.

Alitherm Heritage is available in a choice of standard and non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodized effect finishes.

The Alitherm Heritage door provides the solution for conservation areas where planning regulations require a like-for-like product replacement. The profiles feature the system’s signature slim sightlines and elegant lines that complement Smart’s existing Alitherm Heritage window and 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.
