Who makes the bifold doors IDSystems supply and install?
Our aluminium and timber-clad aluminium bifold doors are manufactured by SUNFLEX. 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 continue to be the most advanced bifold door systems on the market. With more than two decades' experience of fitting these doors, nobody in the world has installed more SUNFLEX bifold doors than IDSystems.
What sizes do bifold doors come in?
Typically our bifold doors are ordered with panels between 800mm and 1100mm wide and between 2100mm and 2400mm high - however the SUNFLEX doors can be engineered to be up to 1200mm wide and up to a massive 3500mm high. We can install doors in a range of configurations from 2-panels up to 22 panels. For a 2-panel system you would need a minimum opening of around 1500mm wide. Because our bifold doors are custom made to your exact requirements we can tailor the design to your exact requirments, so do not hesitate to contact us to see if we can create a bespoke solution for you!
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
Which direction can bifold doors open?
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.
What bifold door configurations can your doors achieve?
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.
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.
Do I need a track for bifold doors?
Our bifold doors are available with a choice of flush (only suitable for internal or extremely sheltered locations), weathered (best suited for exposed or rural locations) or an exclusive low-threshold track that provides a near-flush finish whilst providing an upstand against which the doors can close to form an effective weathertight seal.
What design options can bifold doors achieve?
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.
What can I use instead of bifold doors?
If bifold doors aren’t for you, that’s no problem. Our award-winning sliding doors may be the perfect alternative. Our sliding doors have large glass panels that offer a sleek and minimalist look and have a high-quality finish. They are particularly suited to wide openings (over 5m) or extensions.
