Smarts Alitherm ‘Heritage’ is a range of Aluminium Windows and Doors designed for heritage applications such as conservation areas & listed building where planning constraints are to be considered but works within a modern home environment too.

Smarts Alitherm ‘Heritage’ profiles utilise 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. The U value of a typical heritage window is 1.5 W/m2K (using sealed unit 1.0 W/m2K)
