Liniar Bifold Door Profile


Liniar offered the very first fully bespoke uPVC bi-fold doors to be engineered, designed and manufactured in the UK – and we believe that Liniar bi-fold doors are still the very best.

Liniar’s bi-fold door range has been exquisitely designed for contemporary living. It’s equally as important that Liniar bi-fold doors withstand the worst of the British winter weather as well as help to create a perfect summer ambience.

Our bi-folds have been rigorously tested to ensure that they far exceed appropriate British Standards for weather performance, and subjected to cyclic testing in our purpose-built lab.
