Bi-Folding Doors

About Bi-Folding Doors


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 some of the best.

Bi-fold doors create space, let in fresh air and flood your home with natural daylight by being able to open up an entire wall of your home. Whatever your application, the Liniar bi-fold door provides a truly stunning alternative to French or patio doors.

Liniar bi-fold doors have ultra-slim sightlines, providing rooms with a modern, clean appearance – and are available in a wide choice of opening configurations and colours. An innovative low threshold option makes them family and wheelchair friendly.

Liniar’s bi-fold doors also offer excellent levels of energy efficiency and superb security features. This all adds up to create a beautiful space-saving solution for your property that will also hugely enhance its appearance.

The installation of energy efficient windows, doors and roofs is one of the best ways you can save energy within your home. Innovative uPVC multi-chambered profile design enables Liniar frames to outperform most of the other leadings brands in the UK.

A door’s thermal efficiency is measured in U-values – the effectiveness of a door at stopping the movement of heat into and out of a property. The lower the U-value, the higher a door’s efficiency at preserving the heat inside of a building when cold outside.

The Liniar bi-fold range can achieve a U-value of 1.3 W/m²K when fitted with cost effective double-glazing units so that you can enjoy a warmer and quieter home and lower energy bills.
