Unlike most other window systems, the Liniar range is one of the most modern available and was designed from scratch to take advantage of the very latest developmentsin window engineering technology. The multi-chambered design of the Liniar profile means the transfer of heat and cold is
minimised, keeping your home warmer and your energy bills lower – as well as helping the environment. We also guarantee your Liniar windows are 100% lead-free.

Gone are the days when PVCu windows and doors were only available in white. Our coloured wood-grain foils are applied during the manufacturing process using the very latest in machine tooling – you may
find it hard to believe that the frames aren’t actually made of wood! Or, if it’s the modern look you’re after, you could go for one of our shades of smooth grey – achieve the look of aluminium with the energy efficiency and low maintenance of PVCu. With a wide range of colours and foils available, the choice is entirely yours.
