Aluminium Window Solutions

The Alitherm 300 series offers a range of high quality glazing solutions for side and top hung open out windows suitable for both the residential and commercial markets
All Alitherm 300 profiles utilise 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.
Alitherm products are available in a choice of standard or non-standard colours, including metallic, dual colour and Smart’s Sensations textured.

A modern thermal aluminium solution for both heritage and refurbishment projects where the requirement to replace old steel windows is essential.
Inspired by the design of traditional steel windows, Alitherm Heritage features signature slim sightlines and attractive contours making it the ideal choice for heritage building conservation areas.

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. 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 design drip bar between modules.
