Leading the way – Liniar’s product range.

A continued programme of investment in research and development results in the highest quality products. With 21 patents and 23 Registered Community Designs to protect the range, the Liniar team leads the way in innovation.


From windows with the highest WER (Windows Energy Ratings) to patio doors with the smoothest glide motion, the Liniar range is the ultimate in quality design and engineering.

Every product in the Liniar range has been lovingly designed from scratch by a team of experts, then tested to ensure the finished product will stand up to the rigours of daily living. Manufactured to Liniar’s exacting high standards by a nationwide network of Liniar fabricators across the UK and Ireland, you can be sure of choosing windows and doors that are built to last.

And Liniar’s outdoor range provides a low maintenance, eco-friendly alternative to concrete and timber, with PVC decking and balustrade systems, fencing solutions and attractive log piling to solve your challenges of soil and water erosion and retention.

Liniar windows

Liniar’s 70mm window system was created from scratch, building in innovative design features intended to reshape the accepted standards for PVCu windows. Multi-chambered frame technology means Liniar windows can achieve the highest energy ratings of A++ while at the same time attaining Secured by Design status.

Liniar doors

The profile, or frame, in a Liniar door contains multiple chambers to minimise the transfer of heat from the inside of your property to the outside. This, together with other innovative design enhancements, helps to minimise your energy costs on an on-going basis. The Liniar range includes a beautiful selection of bi-folds, patio and French doors, along with both PVCu residential and composite doors.

Finishing touches

Complete your window installation with perfectly matching roofline products, by choosing Liniar’s high quality fascias, soffits and trims. At 20m thick, instead of the customary 16mm, Liniar fascia boards provide greater strength and, just like Liniar trims, are foiled in the same choice of colours as the Liniar sculptured window suite.

Designed from scratch

The team recognised the need for a pure aluminium bi-fold that fully matched with Liniar uPVC windows – so they designed one!


Superior U-values

With 28mm double glazed and 36mm or 40mm triple glazed units available, Alumina offers ‘true’ U-values as low as 1.3W/m²K, thanks to its innovative thermal lock.


Low thresholds

Liniar’s optional aluminium low threshold is just 23.5mm high at its highest point, requiring no trench excavation to install. Add a low threshold tray to make it Part M compliant.


Foiled ‘warm touch’ exterior

Your Alumina bi-fold can be foiled with any woodgrain or coloured finish – for a beautiful colour match to uPVC windows and doors.


High security

Alumina ensures the highest security with multiple bi-directional locking points, shootbolts that secure firmly into the track, built-in anti-lift features and anti-bump cylinders.


Attention to detail

With innovative features including folding keys, ergonomic handles, hidden fixings for hinges and discreet magnets, the attention to detail is what makes an Alumina bi-folding door ‘best in class’.
