These elegant, concertina doors add a real “wow” factor to any home or premises, and seamlessly connect your outdoor and indoor spaces. Once folded back, they create a large opening for easy access. Particularly suited for new-build projects, these designer folding doors are becoming increasingly popular as property developers seek to differentiate their homes.

Now, thanks to G & B's innovative uPVC bi-fold door design, this exclusive door style is attainable at an attractive price – and it’s easy to fabricate and install too.

G & B has carefully designed its PVC bi-fold door system to offer smooth, simple functionality, with a bottom-rail concertina mechanism, rather than a top-hung system. It’s perfectly sealed against the elements too, with square-edge doors creating a weather tight fit. To maximise the area of glass and the amount of natural light it offers, the door system has slim panel gaps, which also enhances its aesthetic appeal.
