The ideal solution for heritage applications

Designed to offer a modern aluminium replacement to the traditional steel window

‘Choices’ Alitherm Heritage is a modern thermal aluminium solution for both heritage and refurbishment projects where the requirement to replace old steel windows is essential.

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 designed drip bar between modules.

Innovative polyamide thermal break technology

Polyamide thermal break technology 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 and is designed to meet the exacting requirements of Document L 2010. Alitherm products are also available in a choice of standard or non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodised effect finishes.
