Bifold doors

Our aluminium and timber-clad aluminium bifold doors are manufactured by SUNFLEX GmbH in Germany. SUNFLEX have been engineering folding door systems for more than 35 years and their products are sold around the world. We exclusively supply SUNFLEX bifold doors because we believe they are they continue to be the most advanced bifold door systems on the market. With more than two decades' experience of fitting these doors, nobody has installed more SUNFLEX bifold doors than IDSystems.

In theory the number of panels that can be incorporated into a set is unlimited, but we would usually see doors installed with between 3-7 panels. The ability for sliding doors to offer large panes of glass with minimal frames means for wider openings (typically over 5m) sliding doors have become the more popular option.

The big benefit for opting for a design that features an odd number of panels (3, 5, 7 etc) is that the lead door in this configuration can act as a 'traffic-door' for use everyday. You can open this panel, like you would a normal door, to access the patio or garden without needing to open up the entire system.

Our SUNFLEX bifold doors are available in either aluminium or timber-clad aluminium designs. Whilst uPVC and timber folding doors are available they do have their drawbacks, so the innate strength, durability and rigidity of aluminium means that it is the perfect material from which to fabricate bifold doors. With internal timber cladding made from real wood our SF55c and SF75c doors provide a hugely popular alternative to traditional timber doors.

Bifold door systems can be designed to either open inwards or to open outwards. Most often, in external locations, our bifold door systems are installed as outward opening sets because typically there is more space on a patio or decking for the doors to stack than there is on the internal room. When doors are designed as inward opening sets this is typically where the doors are located on a balcony or are connecting a house to a small courtyard garden

We can offer a non-thermally broken aluminium bifold door system, the SUNFLEX SF45. This can be used between a house and conservatory or for connecting a house with a pool room or garage. The system is also hugely popular for commercial premises such as bars and restaurants or for locations such as swimming pools or hospitality venues.

Depending on the number of panels and configuration options bifold doors can be designed to open (when viewed from inside) to the left, to the right or from the centre to each end.

The short answer is that our SUNFLEX bifold doors can achieve any configuration required. From a 2-panel set up to a huge 24 panel system and everything in between. With panels up to 1.2m wide and up to 3.5m high our doors are the most versatile bifold door system on the market so whatever your requirements we can provide you with a solution.

Yes, bifold windows have become increasingly popular. Particularly for connecting kitchens to outdoor seating areas where the ability to completely open up the window allows for the creation of a serving hatch or bar area. We can also incorporate a window alongside a full height set of bifold doors for a real wow-factor.

From open corners to curved sets, our bifold doors can be configured to create a huge range of design options. Check out our design ideas blog for inspiration and ideas for your project.
