A classic opening
Made for your room
Explore bifold steel doors across different interiors, finishes and glazing choices.
Every door is specified for its opening. Glazing, hardware and any fire-rated or thermal specification are confirmed for your project.
How it’s built
Panels fold and stack to one or both sides on a top-hung track. Each panel is a full steel-framed door leaf. The track and stacking configuration are designed around the opening width and the wall run available.
Where it works best
Large external openings to a garden or terrace. Kitchen-dining rooms, living rooms and garden rooms where full connection to the outside is the aim.
How to order it right
Confirm total opening width and stacking direction. Specify number of panels, traffic door position and threshold type. Glass, finish and hardware as standard. Lead time 10 to 12 weeks.

Your questions
Clear answers
How many panels can a bifold set have?
Typically two to six panels for a residential application, with more possible in commercial contexts. We advise on the right number based on the opening width, panel proportions and how much wall run is available for stacking.
Which way do the panels stack?
To one side, or from the centre out to both sides. Stacking direction depends on the opening width and how much clear wall is available on each side. We design the stacking configuration as part of the drawing process.
What is a traffic door and do I need one?
A traffic door is one panel within the bifold set that opens on its own, like a normal door, without folding the entire set. It is the everyday entrance point and we recommend including one on all bifold sets of three panels or more.
What threshold options are available?
Flush threshold with no step at all, low-profile with a minimal upstand, and rebated with a small step. The right choice depends on your floor level relative to the outside and your drainage approach. We advise on this during the drawing stage.
Are bifold doors thermally broken?
Yes. All external bifold doors include a full thermal break and perimeter weather sealing as standard. The threshold is also thermally broken. This is not optional on external doors.
What glazing is available?
Double-glazed units are standard on all external bifold doors. Glass options include clear, ultra-clear, tinted, solar-control and acoustic-rated. We advise on U-values and solar gain for your orientation and specification requirements.
How long does manufacture take?
10 to 12 weeks from drawing sign-off. Larger sets or bespoke configurations may add time. We confirm the programme and any dependencies at the time of order.
Can bifold doors be fire-rated?
Fire-rated bifold doors are not in our standard range. If fire rating is a requirement for your opening, we will discuss the options with you, which may mean a different door type is more appropriate.
Do you install?
Yes. We are based in London and install across the UK. We also supply-only to your contractor anywhere in the UK, and we deliver to European countries. Bifold installation requires care with track level and threshold, so we recommend experienced installers wherever you are based.
What warranty do you offer?
Ten years on frames and glazing, five years on hardware and track. Weather seals carry a five-year warranty and are a maintenance item. Full warranty terms are provided with every order.
