The Perfect Composite Window Designs

Composite windows combine an attractive look and effective functionality of a timber window but have aluminium cladding on the exterior for easier maintenance. One of their main strengths is durability – they won’t warp, rot or expand. The wind and rain will not penetrate the material either, making these windows weatherproof, ideal for the British weather.

Internorm’s modern composite windows have been incredibly popular amongst homeowners due to their versatility, efficiency, and hardwearing properties. Our award winning windows can be easily catered to suit your needs and requirements and matched to the current style of your home.

Our range of high performing windows offers an ideal scenario for all renovation types, including extending and upgrading your residential property or integrating it into a low energy new build. For all designs like triangular, pointed or rounded arches, these styles can also be incorporated to add an extra quirk to your home.

Buying composite windows from Internorm UK will ensure that you are investing in windows that have been perfected from years of manufacturing and supplying experience. As we were established 90 years ago, you can be certain that a trustworthy home improvement specialist manufactures your composite windows.
