Why choose Liniar French Windows?

Liniar French windows are available in our standard or EnergyPlus range, offering a distinctive style of window to shape the look of a home, combined with the practical function of being able to be used as a fire escape.

Including high security locking, Liniar French windows are available in a wide range of colour choices and offer slim sight lines to let in maximum light.

When you choose Liniar uPVC French windows you can forget worrying about draughts – Liniar’s exclusive double-action bubble gasket, used in all its glazed products, keeps your windows leak-free and weather proof by delivering a continuous seal – even in the corners.

Wide range of options

Liniar uPVC French windows can be internally or externally beaded and are available in sculptured (curved) or chamfered (bevelled) 70mm frames, with either 28mm double or 36mm triple glazing.

With a choice of Liniar’s standard 4-chamber profile, providing superb energy efficiency, or Liniar EnergyPlus 6-chamber profile offering A+ WER (Window Energy Ratings) as standard – consumers are also given a wide choice of glazing options, hardware, finishes and choice of colours.

The Liniar supply chain

Liniar’s full product range is designed and manufactured at its state-of-the-art factory in the heart of the UK. The Liniar brand of windows and doors is synonymous with energy efficiency – however, you can’t buy the finished products directly from Liniar.

Using the very latest technology and machinery, the lead-free uPVC frames that are used to create Liniar products are extruded and then supplied to a nationwide network of select window fabricators.

They manufacture the windows and doors to our strict and precise specification, meet individual glazing requirements by adding the glass and then either install the finished products themselves or dispatch them on to independent window fitters.

Why choose Liniar?

Fantastic gasket

Advanced technology

Most uPVC French window profiles still use technology that is 20 years old – or older.

Designed completely from scratch in 2007, Liniar’s multi-chambered uPVC French window profile is far more technically advanced than the majority of window systems on the UK market and was built for the challenges of the modern day by a team boasting more than 500 years of window industry experience.

All Liniar Products are Made in Britain

Made in the UK

HL Plastics’ manufacturing facility is based in the heart of the UK in Derbyshire and extrudes all of the lead-free PVC that Liniar’s French windows are made from.

Boasting the largest PVC mixing plant in Britain, the firm is not only the owner of the Liniar brand but one of the biggest employers in the region, with continued investment in both the factory and facilities keeping Liniar at the forefront of innovation.

Thermally Efficient Windows

Energy savings

Liniar French windows are capable of achieving WER (Window Energy Ratings) A+ with cost effective double glazing and a U-value as low as 0.8 W/m²K with triple glazing – delivering high energy savings for the homeowner at a cost effective price.

We have developed the very latest in multi-chambered profile technology to make sure that the heat stays where it belongs – inside the home.

Better for the Environment

100% lead free

Well in advance of legislation, Liniar French windows have always been 100% lead-free – better for the environment and better for you and your family. You no longer have lead in your petrol or paint, so why choose frames containing lead?

Additionally, every component of Liniar uPVC French windows is totally and simply recyclable at the end of its life – making it more eco-friendly than depleting timber resources.

Keep Heat Inside
