Latest Technology
With uPVC windows traditionally requiring steel reinforcement inside the frames, energy efficiency usually had to take a back seat. But not with Liniar. Its original 70mm window system was designed from scratch using the very latest technology to meet the demands of today’s house building market, resulting in a uPVC window that’s not only strong and secure but also achieves one of the highest energy ratings – all in one system.
Since then, the range has expanded to include a wide range of styles and even greater energy efficiency, right up to Passivhaus standard. Explore the range to find out more.
Casement Windows
A classic window design offering versatility when it comes to style choices, Liniar uPVC casement windows are a market-leading, energy efficient and popular addition to any home. You can choose from 70mm Standard or EnergyPlus profiles or the very latest 90mm Zero|90 profiles.
TILT AND TURN WINDOWS
Liniar uPVC tilt and turn windows are designed to offer a secure, multi-functional style choice, helping to increase a building's ventilation without unlocking. Tilt & turn windows are available in both 70mm and 90mm options.
Flush Sash Windows
The design of flush sash windows takes inspiration from traditional timber joinery, where the sash sits flush within the frame with no overlap. They are ideal for anyone looking to bring a traditional charm to their home and are versatile enough to add a sleek, high-tech appearance to contemporary buildings too. Choose from original 70mm flush sash windows or the unique double-rebated 80mm Resurgence system.
Reversible Windows
The rotating action of Liniar reversible windows means external glass can be safely cleaned from inside the property - making them a safe and secure option for difficult to access areas. Perfectly flush on both the inside and the outside, they look great too!
