Thermally Efficient Aluminium Windows

Aluminium windows are beautiful, contemporary and stylish in appearance. The clean line finish and range of RAL powder coated colours make any building feel wonderfully modern. The fact that the aluminium is thermally efficient means they are super heat insulators and sound proof as an added bonus. The aluminium frame sections are now manufactured in too halves, designed to fit together perfectly in the final product.

The polyamide thermal break is now mechanically joined to the frame sections to maintain the frame’s stiffness and rigidity. Kit-Fab thermally broken aluminium windows are strong, robust and maintenance free, ideal for commercial and domestic projects. Aluminium is very strong and energy efficient due to the thermal break that is part of the profile. When powder coated they are an eye catching and modern looking window. A favourite with architects due to aluminiums strength and slim appearance, which allows maximum viewing area in large windows and doors. These windows can also be laminated. Popular and contemporary is aluminium finished in Anthracite grey.
