The Liniar team is made up of industry experts with more than 500 years of experience between them. They know the challenges you face and find ways to address them.

The latest multi-chambered technology delivers an A++ Windows Energy Rating, the highest achievable – keeping your customers’ fuel bills down. They are also better for the environment and better for family living – your customers will love knowing their windows are free from lead.

With a state-of-the-art factory in the heart of the UK, you can rest assured the Liniar team are on hand to help with any installation queries you may have.

Liniar’s patented double-action bubble gasket means a continuous seal around the windows, even in the corners – so no call-backs to deal with draughts. With a range of thresholds, including Liniar’s patented low-access threshold, together with a choice of security options, your customers will be spoilt for choice.

Matching products include windows, patio, bi-fold, French, residential and composite doors, as well as conservatory roofs, giving installations a seamlessly stunning finish. Furthermore, all Liniar profiles are guaranteed for 10 years against discolouration, splitting, warping or cracking – so they stay looking beautiful for longer.

If you’ve installed uPVC windows with protective tape that’s printed with a green leaf, stating ‘lead-free’, you can be assured you’ve purchased Liniar.

Fabricator benefits

Fabricator Benefits

At Liniar, we always look at the big picture – and by solving your challenges you’ll find the overall cost of your windows and doors (including materials and labour) allows for a greater profit margin for you and your business.
Offering a substantial reduction in the steel reinforcement needed with traditional systems, we have designed the Liniar system with up to two-thirds less steel (based on a GGF standard window) – with absolutely no loss in strength – meaning a huge reduction in manufacturing time, by up to half, and a substantial increase in productivity.

And with Liniar’s patented double-action bubble gasket offering a continuous seal, even in the corners, draughty windows are a thing of the past.
