HBD Systems Logo


The prestigious Sunflex bifold doors system is one of the best for its innovative and distinctive design, German engineering and impressive overall aesthetics and product quality. Not only do Sunflex bifold doors come with some of the best specifications, but they’re also one of the slimmest.

Another of our top-brand folding sliding systems, Sunflex bifold doors offer a different design proposition for your home.  More light, slimmer aluminium profiles, super-smooth folding action, class-leading insulation, security and weather protection are all designed into Sunflex doors. 

HBD Systems are proud to be fully accredited and trained Sunflex partners with extensive knowledge of these premium bifold doors. Each comes with a precision installation and quality guarantee with after-care service.

The Sunflex bifold doors range is cleverly designed to replace any old patio door and, of course, perfect for your newly built extension or home. Compact dimensions, gorgeous styling and elegant looks feature throughout the product.

The sleek lines even extend to the modern door handles, designed to sit in line with the frame profiles, giving you a fully-glazed look where the bifold door handles don’t interrupt the glass line.  


Sunflex bifold doors – created for any design.

The superb craftsmanship and design behind our entire Sunflex bifold doors range not only creates folding sliding doors for standard openings.  Fixed and open corner designs and even curved bifold doors are all possible.  Like all our bifold doors, you benefit from a wonderful extension to your living space and a connection to your patio area and garden.

Sunflex bifold doors go even further with slimmer 115mm or 117mm mullions, more track and threshold options and the choice of more than six different products, all with individual styling, capability and performance.  For standard, large or architecturally designed projects, Sunflex bifold doors promise the perfect finishing touch for your room.

With clever design elements, your new Sunflex bifold doors create an entirely different look and user experience.  Engineered panel catches instead of magnets create a secure door, locking the lead door to the second panel and preventing accidental closing. At the same time, they allow sequential closing of the doors. In addition, the inline door handles are colour-matched to blend with the aluminium profiles and provide an uninterrupted view through the glass.

Peace of mind, security and weather protection with Sunflex

Clever aluminium design, engineered seals, and gaskets ensure your new Sunflex bifold door provides the best possible air, wind and rain protection. In addition, Sunflex doors come with highly insulated aluminium profiles, a durable colour finish and high-specification safety glass.  Depending on the glass type chosen and the level of insulation, U-Values of 0.8Wm2K comfortably surpass current Building Regulations. They are one of the few bifold doors suitable for Passivhaus.

Of course, security is also exceptional, with all Sunflex folding doors having top-of-the-line locking systems and tested to the latest security standards. Safe doors don’t just stop at the locks. Sunflex bifold doors provide child safety features with an anti-slam panel catch preventing child use and finger-safe gaskets.
