Designed by Experts

Designed from Scratch

Many other uPVC window profiles were designed using 20 year old technology – or even older.

Designed completely from scratch in 2007, Liniar’s multi-chambered bi-fold window is far more technically advanced than most other uPVC window systems available in Britain – it truly has been built for the challenges of today.

Better for the Environment

Eco-Friendly

As well as helping to keep more heat inside the property, Liniar bi-fold windows have always been 100% lead-free, well before legislation – you no longer have lead in your petrol or paint, so why choose to have frames containing lead?

And on top of that, every element of Liniar uPVC bi-fold windows can be easily and fully recycled at the of end its lifetime.

uPVC Bi-Fold Windows

Ultra-Slim

Liniar Bi-fold windows allow in the maximum natural light by being designed with ultra slim sightlines.

A larger glazed area results in not only a more beautiful uPVC window, but helps to make the Liniar bi-folding window even more energy efficient and helps to contain and conserve heat within buildings in the winter.

You can say goodbye to draughty uPVC windows for good when you choose Liniar uPVC bi-fold windows.

Bi-Fold Windows

A brand above

Synonymous with energy efficiency, the full product range of the Liniar brand of uPVC 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.

Rest assured that Liniar’s uPVC bi-fold windows have been manufactured, supported and designed by a team with more than 500 years of experience within the window industry.
