Revolutionary Modlok™ Bifold Doors

With their concertina opening style and wonderfully slender sightlines, Modlok™ bifold doors add an element of class to any location, whilst allowing natural light to flow in unabatedly. In terms of strength, security and durability, their patented exoskeleton design means they excel in these aspects too.

Tested to an incredible 127,000 opening cycles, there is a reason why the Modlok™ system received a Queen’s Award for Enterprise in Innovation in 2017. An award-winning system built and supplied by an award-winning manufacturer, these revolutionary PVCu bifold doors are available with a Part M compliant threshold, in numerous colours and configurations, and with sculptured or chamfered frames.

Liniar Modlok Bifold Doors Features:

Providing a sophisticated and streamlined appearance, we can manufacture our PVCu bifolding doors to fill small and larger apertures alike. Wherever they are required, however, they guarantee an outstanding level of protection and comfort, whilst they are an excellent space saver because of their folding panel design.

The use of low maintenance, high-quality PVCu only adds to their practical appeal. Plus, the Liniar profiles we use are 100% lead-free and completely recyclable at the end of their life, meaning they lead the way in terms of sustainability also.
