Alitherm Heritage

The Alitherm Heritage is a modern, thermally efficient solution for heritage properties and sympathetic refurbishment projects.

Alitherm Heritage is the perfect solution for those looking for period style windows with modern functionality. The range has been designed as a series of horizontal modules which can form a multi-section window. A drip bar has been created between each module to produce the desired heritage appearance.

Innovation at its finest

Using Smart’s cutting-edge thermal technology, the profile’s polyamide thermal break achieves an insulating barrier between inside and out, reducing thermal transmittance. This has produced a window with an impressive u-value, designed to meet the rigorous requirements of Document L 2010. 

Signature Slim Profiles

Ideal for home renovations, narrow sightlines and slimline profiles define the appearance of the Alitherm Heritage collection.
