We source our uPVC window range from Liniar Windows

Liniar Technology

Most uPVC window systems haven’t fundamentally changed since they were first launched in the 1980s – and with uPVC traditionally requiring steel reinforcement inside the frames, energy efficiency usually had to take a back seat. But not with the Liniar 70mm system – it was designed from scratch using the very latest technology to meet the demands of today’s house building market. This resulted in a window that’s not only strong and secure but also achieves one of the highest energy ratings – all in one system.

The Liniar design team continues to push the boundaries, creating new products and enhancements to ensure the range is the most innovative and sought-after on the market.

Enviromentally Friendly

Energy bills are on the increase, environmental concerns are higher on the agenda than ever before and building regulations are becoming more demanding every year. Choosing a window system that offers higher Windows Energy Ratings for a lower cost therefore makes good sense.

MADE in Britain, HL Plastics designs, extrudes and tests the Liniar uPVC window range at its state-of-the-art factory in Derbyshire and each window in the Liniar range is made from lead-free, energy efficient, recyclable uPVC, making them a sustainable choice.
LINIAR uPVC windows are covered by the 10-year guarantee against warping, splitting or cracking.

Casement Windows

LINIAR Casement windows offer total versatility with traditional British style offering slim sightlines to let in maximum light to brighten your home.
KEEP HEAT INSIDE With a standard four chamber or unique six chamber PVCu profile, EnergyPlus can easily achieve an A+ rating, helping you to contain and conserve heat within your property and save on energy bills.
TRIPLE GLAZING Liniar casement windows are available with 28mm double or 40mm triple glazing – capable of achieving a U-value of 0.8 with EnergyPlus profile whilst reducing noise.

Flush Sash Windows

A+ RATED WINDOWS Liniar flush sash windows, like the rest of the Liniar EnergyPlus window range, are A+ rated. They offer a lower cost window with higher thermal benefits than timber – in addition to being fully secure.
FLUSH sash windows are the latest exciting development from Liniar. They offer the realism of a traditional pre-1932 timber window combined with 21st century thermal benefits.

Tilt and Turn Windows

VERY MUCH A European design, the Liniar tilt and turn window allows you to let in fresh air while also offering security. The open in style gives great options for cleaning from within (in the turn position) and secure ventilation (in the tilt position).
OFFERING A greater scope for larger openings than a traditional casement window, Liniar’s tilt & turn windows are ideal for high-rise as well as low-rise applications, and thermal performance is helped by the larger panes of glass.Perfect as a fire escape or simply to let in more fresh air, Liniar tilt & turn windows are available in both ‘tilt before turn’ or ‘turn before tilt’ options.
