Less frame, more glass

Liniar standard bi-fold doors have ultra-slim sightlines, providing rooms with a modern, clean appearance – letting in the maximum amount of natural light.


Our standard bi-fold doors have been rigorously tested to ensure that they far exceed appropriate British Standards for weather and security performance.


Slim hinges have been added, with hidden fixings inside – increasing security as it is impossible for them to be unscrewed externally.

First, bespoke designed bi-fold

The Liniar standard bi-fold was the first bi-fold door on the market to be designed from scratch.


Liniar standard bi-fold doors are available in a range of opening configurations from 2 to 4 panes so they can be truly tailored to your requirements.

Customer choice

Liniar standard bi-fold doors are available with a range of additional options, from handles and hinges, to low and half thresholds.






A few reasons to choose us for your next bi-folding doors

Created for today’s challenges

Liniar’s bi-fold door range has been exquisitely designed for contemporary living.

It’s equally as important that Liniar bi-fold doors withstand the worst of the British winter weather as well as help to create a perfect summer ambience.

Our bi-folds have been rigorously tested to ensure that they far exceed appropriate British Standards for weather performance, and subjected to cyclic testing in our purpose-built lab.

Low maintenance

You can rest assured that you won’t need to spend hours looking after your set of Liniar bi-fold doors to maintain their beauty.

Unlike timber, you won’t need to treat or paint them each year to keep them in top condition – and that’s not all; our 10 year frame guarantee gives you the peace of mind that the colours won’t fade.

All that is needed to keep them looking their best is an occasional quick wash with soapy water.

A seamless entrance

Ideal for family homes, the Registered Design protected Liniar low-threshold option creates a seamless entrance and exit without the need for messy and expensive excavation.

An easy-access ramp, for wheelchairs and prams, can be created using an optional tray to seat the low threshold.

Measuring just 24mm at its highest point, the ultra-low Liniar threshold is available in a choice of silver or gold finish, perfectly complementing the door hardware.

Grand design

Bi-fold doors are now more popular than ever and are fast becoming the must-have home improvement.

Aluminium and timber are often thought of as the standard materials for bi-folds, but uPVC offers many more benefits; superior thermal efficiency, smooth operation, perfect matching of windows and doors and minimal maintenance.

Your bi-fold doors will rival the most contemporary aluminium range on the market.
