Queens Award-winning uPVC ModLok™ bi-fold doors by Liniar offer unparalleled energy efficiency, strength, security and durability, thanks to a unique, patented aluminium exoskeleton.

Award-winning design

The Liniar ModLok™ bi-folding door range is unique, combining the energy saving benefits of uPVC with the strength, security and stability of aluminium bi-folds. This is all thanks to its patented exoskeleton – an aluminium perimeter encasing the outer edge of each

uPVC pane – with a modular locking mechanism which helped the ModLok™ bi-fold win a coveted Queen’s Award for Innovation in 2017. 

stunning aesthetic

A stunning addition to any home, a set of bi-fold doors enables you to open up an entire wall of your room – and with ModLok™ bi-folds spanning up to 7 panes wide (see the different ModLok™ bi-folding door configurations available) they can provide a cost-effective alternative to aluminium for larger openings.

stress free

Even better, all Liniar bi-folding doors are bottom rolling, not top hung – meaning no extra stresses are placed on the lintel.
