One of the newest most technically advanced window systems on the market, the Liniar system was launched in 2008 by bringing together some of the window industry’s most experienced and forward thinking designers and a technical team with more than 500 years of industry experience between them.
Liniar’s range of window and doors has been designed to meet the demanding requirements of today’s construction market. Reducing installation time while increasing energy efficiency, the Liniar system continues to lead the way – beating legislative requirements and building regulations well in advance of due dates.
Liniar’s range of casement windows, French windows, tilt and turn windows and reversible windows, along with residential French doors, bi-folding doors, patio doors, and composite doors are suitable for installation into low-rise and high-rise applications, social housing, new build developments and refurbishment projects alike – providing cost effective, high quality, energy efficient products for both residential and commercial developments.
The Liniar range is fully accredited – it’s important to us to prove our products are backed by the highest standards and an ongoing testing programme ensures that all systems and products remain fully compliant.
As the market for windows and doors becomes ever more technical, and legislation and building regulations more demanding, it’s reassuring to know that Liniar windows and doors meet and exceed all the requirements of the social housing and new build sectors.
Liniar has an extensive range of products, all of which were designed to exceed the conditions of UK building regulations, and offer the highest standards of security. They are all designed with the latest technological advancements, and all products are lead free in their composition.
