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.

Continued investment in design facilities, tooling and machinery ensures the very latest techniques are used to create each component within the Liniar system.
