Our UPVC Bi-folding doors add a new dimension to any room, sliding smoothly and folding effortlessly to allow the outdoors in.
Energy efficient – one of the best ways any home can save energy is through installing energy efficient windows, doors and roofs.
Liniar frames outperform most other leading UK brands when it comes to thermal efficiency, mainly due to their innovative multi-chambered profile designs.
The standard Liniar bi-fold door can achieve a U- value of 1.3 W/m2K when fitted with cost effective double glazed units.
Lead-free – better for the environment – All Liniar profiles are 100% lead-free UPVC.
Purpose designed – The decorative sculptured UPVC sections are slimmer than a standard UPVC door profile meaning more glass area, particular relevant when you consider these doors can be manufactured up to 7 panels wide.
Just as important, is that all the locks, handles, hinges and wheel assemblies have also been designed by Liniar, resulting in a bi-fold door that performs and operates in the manner it was engineered to do so.
