Overview
Made to Fit Your Home, Not a Catalogue
Each bifold set is built to your exact opening width, not a standard panel count, so the track length and stacking direction suit the space itself.
Panels run on a top-hung track for smoother operation, with a low-level threshold option available where step-free access matters most.
Key benefits
- 2 to 8 panel configurations
- Top-hung, smooth-glide track
- Low-level threshold option
- PAS 24 security tested
- 20+ colour and foil options
- 10-year insurance-backed guarantee

Product Engineering
Panel and Track Construction
A bifold door is only as good as what you can’t see. Interlocking panels compress a weather seal at every join, locking out wind and rain across the full width of the opening. A steel-reinforced top-hung track carries the weight, not the floor, so the doors glide smoothly on day one and still do years later.
That’s engineering, not luck.

FAQ's
Questions About Bifold Doors
Often the existing opening works as-is, though structural changes are sometimes needed for wider spans. We confirm exactly what's required at the survey stage.
Configurations typically run from two panels up to eight, depending on the opening width. More panels mean a wider view but a longer stacked footprint.
Not when properly installed. Compression seals between panels and a thermal break in the frame perform close to a standard door's insulation levels.
Yes. Shootbolts engage into the track and threshold independently of the handle, so the doors can be secured in any stacked position.
An occasional clean and a check that rollers move freely. Track mechanisms are built for daily use, not the light traffic of a single hinge.
