Whichever you choose, the aluminium windows can provide exceptionally low U-values, which surpass the requirements of the new building regulations. Get a quote for your aluminium windows today.

Thermally broken aluminium windows

What is a polyamide thermal break? It occurs when a thin layer of high-performance plastic is inserted between the inner and outer frame of the aluminium profile. As aluminium is a natural conductor of heat, this sheet creates a 'break' that significantly slows the rate of thermal transfusion. This allows for buildings to enjoy all the aesthetic and security benefits of aluminium windows without having to settle for anything less than outstanding thermal performance. This thermal break, combined with the incredibly efficient double glazing, makes our aluminium windows capable of keeping any home across the UK warm, dry, and comfortable all year round.
