Composite Windows UK specialise in high-end composite, timber and aluminium windows and doors.
We have partnered with the DOVISTA Group to offer both Rationel and VELFAC brands. We also supply Solarlux folding and sliding doors, glazed extensions and Spitfire entrance doors.
Both the VELFAC and Rationel composite product ranges bring together the best of both worlds. They offer the durability and versatility of aluminium, together with the beauty and warmth of natural wood.
Rationel windows and doors are also available as fully timber product. All Rationel windows and doors have an iconic Scandinavian design that’s driven by detail. The result is something that truly stands out from the rest.
The VELFAC 200 system aluminium/wood windows and doors deliver contemporary styling. The slim 54 mm sightlines maximise natural light. Opening and fixed lights have the same sightlines, providing a consistent aesthetic across window units.
Rationel and VELFAC products are designed for the future. Using sustainably-sourced timber and exceptional craftsmanship, they’re built to last for decades and to be enjoyed for generations. Both the Rationel and VELFAC brands have a commitment to high performance and thermal efficiency. As a result, they promise a cosy and optimal indoor climate every time.

Composite Windows UK offer Solarlux bi-folding and sliding doors as well as thermally insulated and non-thermally insulated glazed extensions and canopies.

What Our Clients Say

Thank you to you and your team for completing this job. The windows are great and you did a fantastic job getting them in on one day! We would be happy to recommend you to others.
Fred, United Kingdom
We had all our windows replaced and installed VELFAC using Westcott. They were incredibly helpful and went the extra mile to ensure we could get what we were looking for. They worked alongside our builders who were renovating the rest of our property and in the main this worked well.
Alistair, Haywards Heath
What makes this company stand out is outstanding customer service from start to finish. I had VELFAC 200 Energy windows installed for a new self-build so attention to detail was paramount. Composite Windows came to site multiple times before, during and after fitting to ensure the product was perfect. When one of the larger units was difficult to close, they sent their engineers to adjust it but still determined it wasn’t perfect, so replaced the entire unit. Its the service we all would hope companies strive to deliver but we typically settle for less. Composite windows really did deliver on my project. They have a great team in the office and at site. I would definitely use them in subsequent projects.
