Why uPVC?

As one of the most cost-effective, thermally efficient, non-toxic and versatile materials on the planet, uPVC is the ideal solution for windows, doors and conservatories.

Did you know… uPVC (unplasticised PolyVinyl Chloride) was the term used in Britain before the name was changed to uPVC in the late 1980s to fall in line with the rest of Europe. It’s called uPVC on the continent because most European languages place the noun (the word PVC in this case) before the adjective (U).


1. Thermal efficiency

With 10x more uPVC windows achieving an ‘A’ rating from the British Fenestration Rating Council than their nearest alternative – it’s yet more proof that uPVC is one of the most energy-efficient materials on the market.

uPVC windows are designed to keep warmth within a property and keep the cold out – offering homeowners on-going savings on their energy bills. Liniar takes this a step further – with its multi-chamber uPVC window profiles which trap air and create a thermal barrier. When combined with double, triple or quadruple glazing, U-values of as low as 0.8W/m²K can be achieved.


2. Benefit vs. cost

When fabricators or installers choose uPVC as their medium for fabricating or which windows they install, the benefits far outweigh the cost. When you compare uPVC with its counterpart’s timber and aluminium, uPVC windows offer:

  • A lower purchase price and installation costs
  • Higher energy savings over the life of the windows
  • Lower maintenance costs


3. Low maintenance

Effortless to maintain throughout the period they’re installed, uPVC windows simply need to be wiped down with warm, soapy water to keep them looking their best. If windows have been foiled with a woodgrain or solid colour and need a touch-up or repair, a RAL-matched pen will do the trick.

In contrast, timber windows are notoriously high maintenance, needing regular painting or treatment – which is not only time consuming but costly. Aluminium windows can fade and oxidised with exposure to the sun, requiring specialist cleanings and coatings to restore.


4. Durable

With a lifespan of up to 35 years, uPVC is the long term solution property owners are looking for. Windows fabricated from uPVC will not rot, warp, split or corrode, and with special additives, uPVC even suits harsher European requirements.

uPVC is a lighter material than the alternative, and thanks to this lightweight nature, uPVC windows are easier to handle and install – reducing time on site for fitters and contractors.


5. Attractive

The unsightly uPVC windows of the 1980s with their chunky white frames are a thing of the past. Liniar offers a wide range of foils in both solid colours and with woodgrain effects. uPVC can provide the beauty of a timber window with timber alternatives like the Resurgence double-rebate flush sash window or the slim sightlines of an aluminium window.

Designs have advanced significantly and timber replica windows with the pre-1932 flush sash style offer a contemporary, more energy efficient alternative in conservation areas where timber is preferred.


6. Weather-proof

Created to withstand the damp British weather, uPVC windows will not swell or rot and Liniar’s patented co-extruded bubble gasket ensures excellent resistance to air and water.

Timber and aluminium frames are both fabricated in a way that their weather seals are added during fabrication and joins can also shrink back over time, causing gaps in the seals. With Liniar’s uPVC windows, the gaskets are added as a part of the extrusion process, providing a continuous seal all the way around the window, eliminating draughts for longer.


7. Eco-friendly

It’s time to squash the myth that uPVC is not sustainable or environmentally friendly.

Liniar has worked tirelessly to change the public’s perceptions about uPVC windows. uPVC windows from Liniar are 100% lead-free, better for families and the environment and they’re produced in a zero operational wastage facility with an incredibly low scrap rate.

Family-friendly, uPVC is completely non-toxic. The elemental makeup of uPVC includes an essential nutrient. Made from a recipe including salt and other non-toxic ingredients, uPVC is completely safe for growing families and offers more robust insulation than alternative materials. Patrick Moore, Co-Founder of Greenpeace stated that PVC is one of the most non-toxic, energy efficient, versatile and cost-effective materials we have in all of society.1

uPVC windows are 100% recyclable and can be recycled up to 10 times – giving each window an estimated lifespan of 350 years – far more eco-friendly than depleting the Earth’s timber sources.

According to the British Plastics Federation, uPVC applications throughout the construction industry are on the rise. The material offers versatility with excellent weight to strength ratio, durability, corrosion resistance, low maintenance and cost-effectiveness making it an attractive choice for specifiers, builders and fitters.2
