Liniar Products Hertfordshire | Window Wise

Liniar has been around since 1974, when it established its roots. The company’s values focus on doing what is right and being friendly to others while maintaining their commitment in people-led investment with innovation for product development, sustainability at every step of the production process and strict quality control. The 2008 launch of Liniar’s flagship window profile was a revolutionary moment for the UK uPVC industry. Completely designed from scratch, it introduced an entirely new type that had not been seen in nearly two decades – with unrivalled energy efficiency and design features to address older profiles’ issues. The Liniar range is one of the most innovative in its field and it continues to raise both bar for research, development or design with every new product that comes out.
