Choose a layout that folds away cleanly

Stack position planned

We make sure folded panels have clear space and don't block the route.

Access leaf included

A practical everyday leaf can avoid folding the complete set each time.

Panels adjusted together

Track and hinge settings help several connected leaves move smoothly.

Fold back more of the opening

Bifold doors use several connected panels to open up a larger part of the wall than a typical hinged or sliding arrangement. When folded back, they create a strong link between the room and garden; when closed, the glazed panels retain wide exterior views. We plan the panel number, stacking direction and everyday access leaf around how you will use the space. Frame finish, glass and threshold choices shape the appearance and practical access. The folded stack also needs somewhere sensible to sit, so clear space at the side cannot be treated as an afterthought.

Tracks, panels and locks working together

The structural opening must be measured accurately before a bifold system is specified. We check width, height, level and the intended stacking area, then confirm how the panels will move. During fitting, track alignment and panel adjustment receive close attention because small errors can make several leaves bind together. We test the everyday access leaf, hinges, rollers, locking points and seals across the full opening. Compared with French doors, bifolds can create a broader clear space. Sliding doors use less stacking room, but leave more of the opening fixed.

Frequently asked questions

How many panels should my bifold doors have?

The right number depends on the measured opening, preferred panel widths and where the stack should sit. We also consider whether you want an everyday access leaf for quick trips outside.

How do bifolds compare with sliding patio doors?

Bifolds can open a larger proportion of the full width but need room for the folded stack. Sliding doors avoid that stack and use no swing space, although part of the glazed opening remains fixed.

What prevents bifold panels from sticking?

Accurate structural measurements, level tracks and careful panel adjustment are vital. We test hinges, rollers, locks and seals across the full run so binding can be corrected before handover.
