Services
SUNFLEX UK is a renowned manufacturer of superior quality glazing systems, including award-winning bifold doors and sliding doors. We supply our advanced door and window systems to the glazing trade and work with a carefully selected network of glazing trade distributors across the UK. We have over 20 years' experience as a bifold and sliding door manufacturer.
SUNFLEX bifold doors have been installed around the world since 1986, offering the widest range and setting the standard for folding doors - including aluminium and timber-clad aluminium systems. Bifold patio doors blur the lines between inside and out. Thanks to their slim, contemporary designs, SUNFLEX bifold door systems fill rooms full of light when closed and merge your home with your garden when open.
The ability to completely open up the corner of an extension or self-build can totally transform a project. Our SUNFLEX doors pioneered the moveable post technology that makes it possible. We've been supplying bifold doors with open corners for 20 years, creating a real design statement in homes across the UK.
The SUNFLEX range of faceted bifold doors are the ultimate option for contemporary designed homes that call for curved glazing, creating a stunning appearance when closed along with the ability to provide a seamless transition between inside and out when opened.

Whether you require a set of doors that curves inwards (concave) or outwards (convex), the SUNFLEX systems can be configured to your exact requirements, and we can provide detailed technical information to support the initial concept, turning an idea into a practical and achievable design.Creating curved bifold doors is possible because of the advanced engineering and design of the SUNFLEX aluminium systems.
The SUNFLEX range of SF55c and SF75c timber clad aluminium bifold doors provides the perfect combination of aesthetic appeal and performance, matching the natural beauty of wood on the internal face of the door with maintenance-free aluminium on the outside. By including timber cladding on the inside of the door, SUNFLEX doors benefit from a much slimmer design all round than timber doors with aluminium cladding on the outside.

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,
Peter Messenger

I just wanted to thank the team at Sunflex for there help with our bifold doors and roof. Our architect designed an extension that turned out to be unnecessarily complex but thanks to Lee at Sunflex, their factory and our installers we managed to find a solution to make it work!

Having specified a range of bifold and sliding doors for client projects over the years but never been completely comfortable with the quality of the systems or installations, we stumbled across Sunflex doors at an exhibition and were impressed by the design and attention to detail. We have been specifying the doors ever since and cannot praise the service and expertise highly enough!
