Alitherm Aluminium Window The Smarts Alitherm 300 window range is designed to offer a complete solution, whether you are replacing your old windows or need new windows. It is ideal for an extension or construction project for both the residential and commercial markets.

Alitherm 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 and is designed to meet the exacting requirements of Document L 2010.

Alitherm products are available in a choice of standard or non-standard colours. One of the most significant advantages of aluminium windows is a considerable colour choice. We offer a range of standard popular colours such as white, black, grey or brown. There is also a choice of different colours inside and out to complement your property and your decor.

The Alitherm 300 system features an extended polyamide thermal break, which improves the overall U Value of the profile, allowing Alitherm 300 to achieve a Window Energy ‘A’ Rating when used in conjunction with the correct double or triple glazed unit.

An alternative for Listed Buildings
Alitherm Heritage 47 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. Slim sightlines ensure for a stylish appearance, while considerable amounts of light can make its way through the window. Tested to BS6375: Part 1, the Alitherm Heritage system is fully weatherproof. Plus, each window is fitted with polyamide thermal breaks, significantly bolstering their ability to retain heat.

David Strange | London
Really great job done by Peter and his team. They replaced all the windows in our 3rd floor flat, quickly and matching the old design exactly. Peter provided very helpful advice as to which type would be best for our needs (we went for double glazing with extra accoustic glass) and he also gave us a full break down of the pricing etc. Not at all pushy, just a decent window fitter who did a very professional job. We have already recommended them to all our neighbours and I would highly recommend South East windows to anyone.

Can't tell you how happy I am. Peter fitted french doors and side panels last month for me. Great service from first visit for quotation to completion of work. Straight forward no nonsense, what you see is what you get! Peter worked tirelessly and the level of workmanship was second to none! The doors look fantastic and the finish is perfect! Thank you so much Peter. I will definitely be back for the windows very soon. I would not hesitate to recommend you to anyone. Great quality, workmanship and price!
