Smart’s Alitherm Heritage system is designed as a direct replacement for old steel windows, without losing the look that makes period properties special. It is built for listed buildings, conservation areas and large-scale refurbishment projects, where planning requirements call for a faithful match to the original design. Polyamide thermal break technology cuts heat loss and helps the system meet current building regulations, while typical sightlines of around 59mm keep the slim, elegant proportions homeowners expect.
Tested to PAS 24:2016 for security and BS 6375 for weather performance, Alitherm Heritage windows and doors are available with heritage and art deco hardware, finished in single or dual colour powder coating.
AluK’s heritage systems bring the narrow look of traditional steel windows to a thermally broken aluminium frame. The window range offers slim sightlines, a choice of colours and anodised finishes, with top, bottom, side hung and French casement configurations suited to period and industrial-style conversions. It carries Secured by Design accreditation and a WER A rating for genuine thermal efficiency.
The matching AluK heritage door delivers sightlines from as little as 51.7mm, with single, double, open in and open out configurations, plus coordinating heritage hardware in four finishes for a considered result across your whole home.
