A choice of uPVC Bi-folding Doors

Liniar was first to launch a fully bespoke uPVC bi-fold door engineered, designed and manufactured in the UK, with the Standard bi-fold.

Two years later, the ModLok™ bi-fold system was introduced – a feat of engineering, with a combined lock and reinforcement system giving it the ultimate in strength.

The Standard bi-fold is ideal for apertures up to four panes wide, and comes in a wide choice of styles, opening configurations, thresholds, colours and finishes.  Find out more about the Liniar Standard bi-fold here.

The Liniar ModLok™ bi-fold is a fully uPVC system with the added benefit of a patented exo-skeletal aluminium reinforcing system enabling it to span widths of us to 7 panes wide. Find out more about the Liniar ModLok™ bio-fold system here.

Both Liniar uPVC bi-folds are made from the same high quality lead-free materials and fully guaranteed.
