Bifold doors

Award-winning SUNFLEX bifold doors that are packed full of innovative features, available in aluminium or timber-clad aluminium

Let the outside in

With the ability to open up the doors completely, bifold doors are perfectly for letting the outside in.

When stacked to one end bifold doors create a completely unobstructed opening that is ideal for connecting your house and garden, extending your living space out on to patio to create a contemporary entertaining space.

Available with narrow aluminium frames and incredibly slim frame depths from just 55mm and individual panels up to 1.2m wide and 3.5m high, our SUNFLEX bifold doors are custom made to your exact requirements in the widest range of configurations, including open-corner sets or integrated alongside fixed frame windows to create a consistent design solution.

Precision engineered bifold doors

Designed with more than 30 years of bifold door experience, our range of SUNFLEX bifold doors offer industry-leading performance and are packed full of unique features and exclusive options not found on any other manufacturer’s bifold doors.

The SUNFLEX aluminium bifold doors include the SF55, an award-winning bifold door system with narrow frames that is available double glazed or triple glazed; and the SF75, the most thermally efficient bifold doors system on the market.

Alternatively you can opt for the SUNFLEX SF55c or SF75c timber-clad aluminium bifold doors, that combine maintenance free aluminium on the outer face of the bifold door frame with the natural beauty or real wood on the internal face.

How many panels can a bifold door set have?

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.

Is there a benefit to having an odd-number of panels?

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.

What materials are bifold doors available in?

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.

Can bifold doors open inwards or outwards

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

Do you offer internal bifold doors?

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.

Can I use a bifold door as a window?

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.
