Zero90R for retro fit

uPVC Casement Windows
Liniar's 90mm uPVC casement windows, are unlike any other casement windows in the UK today. They may look similar from the outside, but the technology included inside the frames gives them one of the highest whole-window energy performances on the market.

Mindful of the challenges faced by installers, Liniar's 90mm system can also be retro-fitted into existing cavities without disturbing the internal finishings
