Bi-Fold Windows

With the ability to enhance almost any type of building, whether modern and contemporary or traditional, Liniar bi-fold windows enable you to fully open one side of a room while retaining valuable wall space for furniture inside.

Liniar bi-fold windows are popular for use in Conservatories and Orangeries and are also ideal for the commercial sector. During the summer months they can transform a café or restaurant and give an establishment an outdoor, open feel, while also being secure and child-friendly.

Goodbye to draughts

Manufactured in the UK, the Liniar bi-fold window is available in a wide choice of pane options and colours.

You can say goodbye to draughty windows for good when you choose Liniar uPVC bi-fold windows. All of our products benefit from the unique Liniar patented double-action bubble gasket – ensuring that windows are weather proof and leak-free by delivering a continuous seal, even in the corners.

A brand above

Synonymous with energy efficiency, the full product range of the Liniar brand of windows and doors is manufactured and designed at its purpose-built Derbyshire premises – however, Liniar doesn’t sell the finished products directly to homeowners.

The lead-free uPVC frames that are used to make Liniar products are extruded using the most up-to-date methods and machinery. These are then distributed to a wide network of window fabricators who create the Liniar bi-Folding Windows to our exact and meticulous specifications.

Glass is added to meet individual glazing requirements, then fabricators will either install the finished articles themselves or sell them on to independent window installers.
