Heritage Meets Modern Performance

Alitherm Heritage provides the ideal solution for heritage applications such as listed building renovations and large scale replica-refurbishment projects where planning constraints are to be considered. This modern thermal aluminium system is designed to replicate the aesthetic of traditional steel windows and doors while delivering contemporary thermal performance and security standards.

The system utilises Smart's innovative polyamide thermal break technology which creates a barrier between the cold air outside and the warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U Value of a product, designed to meet the exacting requirements of Document L 2010.

Available in a choice of standard or non-standard colours, including metallic, dual colour, textured finishes, and anodised effect options. The slim 59mm sightlines maintain the authentic heritage appearance while incorporating modern multi-point locking systems and 316 Marine Grade Stainless Steel hardware options for durability and security.
