Alitherm Heritage 47 has been designed to offer a solution for heritage properties & building renovation projects where there is a need for a modern replacement for old steel. Replace your old drafty steel doors with modern secure, thermally efficient steel replacements.

Replicate the appearance of traditional steel doors from a bygone era with classic glazing bars & panel designs to create a vintage look. The Alitherm Heritage 47 door is the ideal replacement for steel doors on heritage applications such as building renovations or apartment conversions.

The Alitherm Heritage 47 door provides the solution for conservation areas where planning regulations require a like-for-like product replacement. Alitherm Heritage door profiles feature the system’s signature slim sightlines & elegant lines that complement Smart’s existing Alitherm Heritage window & 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.

Alitherm Heritage provides the ideal solution for heritage applications such as listed building renovations & large scale replica-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 design drip bar between modules.

Alitherm profiles utilise Smart’s innovative polyamide thermal break technology which creates a barrier between the cold air outside & the warm air inside. This technology significantly reduces thermal transmittance & enhances the overall U Value of a product & is designed to meet the exacting requirements of Document L 2010.
