Bifold Doors
Our bifold doors combine slim aluminium frames with advanced security features, offering seamless transitions between indoor and outdoor spaces. Available in custom configurations, they provide exceptional thermal efficiency and weather resistance. Designed for both residential and commercial properties, these doors maximise natural light while maintaining structural integrity.
Sliding Doors
Engineered for large openings, our sliding doors feature ultra-slim frames and high-performance glazing. They offer effortless operation and superior weather tightness, ideal for extensions and modern homes. The systems incorporate advanced locking mechanisms and can span up to 24 metres in width.
Heritage Doors
These doors merge traditional aesthetics with modern performance, replicating the look of steel with thermally broken aluminium. Suitable for period properties and new builds, they meet current building regulations while offering enhanced security and insulation.
Glass Roofs
Custom-designed glass roofs provide natural light and thermal efficiency for extensions and patios. Our systems include lean-to, lantern, and terrace options, all engineered for durability and minimal maintenance. Solar-control glazing reduces heat gain without compromising visibility.

Flexible internal partition systems create open-plan spaces with acoustic insulation and sleek aesthetics. Options include sliding, bifold, and frameless designs, suitable for residential and commercial environments. These systems enhance spatial versatility while maintaining design continuity.

Just had Sunflex bi-fold doors installed in my house. Very impressed with the quality of the doors. Very smooth sliding action, and clearly a high quality finish. The anthracite grey colour finish on the frame looks very smart too. Highly recommend.

Guys,
I felt it now appropriate on behalf of aluhome here in Stamford, after partnering with you for just over the last six months to say a very big thank-you. My company has grown exponentially through its strategic partnerships and without them we would not have a business. I chose Sunflex as one of aluhome's preferred partners because after reviewing all the UK's and Mainland Europe's aluminium sliding door offerings, the Sunflex SVG20 & 30 product range stood out from the crowd with both its visual differentials and its precision engineered transitional movement. Your friendly service,

We have been specifying the doors ever since and cannot praise the service and expertise highly enough!

Sunflex's door was finally ready after 10 weeks of waiting! My excitement for it to be fitted was indescribable. However When the door turned up soon they'd found out they couldn't find the keys. Then they tried to fit it on the walls until they discovered a bigger problem! The door was made wrong way round, opening the wrong side therefore the fitters had to put it upside down for it to open the right way, however this soon proved to be unrealistic as the door was custom made, so it won't lock even if they found the keys. Which they didn't! It's falling apart around key hole area and simply can
