Alitherm Heritage Doorsets

Fully compliant with Document L of the Building Regulations, the Smart Alitherm Heritage range of single and double doors provides an elegant solution for both new build and refurbishment projects.

The doors’ distinctive slim sightlines perfectly complement Smart’s existing Alitherm Heritage window range, which together mimic the appearance of traditional steel windows and doors – while delivering all the performance benefits of a modern aluminium system.

Providing a ready replacement for steel doors on heritage applications, such as building renovations or apartment conversions, Alitherm Heritage doors are suitable for sensitive conservation areas, where planning regulations require a like-for-like product replacement.
