SUNFLEX UK is a manufacturer of bespoke aluminium doors systems, including our award-winning bifold doors and sliding doors. These products are supplied by recognised SUNFLEX UK distributors across the UK, ensuring you receive the products and installations that meet the highest standards of quality.

We’re committed to creating products that stay at the forefront of innovation. In addition to their stunning contemporary designs, our doors feature robust security locking systems, high insulation value and superior thermal efficiency and weather tightness. This combination of design and functionality has produced doors that have won various certifications and awards, and are proudly being displayed in homes and businesses across the UK.

To ensure our customers receive an installation service that matches the quality of our products, back in 2000 we created a training scheme a trading scheme that enables collaboration between SUNFLEX UK and our distributors.

At SUNFLEX UK we are not reliant on third party suppliers for our products. Every door, window or roof system we sell is made in one of our own manufacturing facilities in the UK or Germany, ensuring the highest quality and attention to detail.

Our experienced teams of fabricators are specialists in the production of aluminium glazing systems and our factories hand-make bespoke systems that are manufactured to order.

We are always more than happy to offer production tours of our facility to our trade customers and distributors. For more information contact us at info@sunflexuk.co.uk or call us on [ld_default].
