Why choose Linear?

Liniar casement windows continue to be the most popular option for homes across the UK because they offer complete adaptability.

This classic British uPVC window design features thin sightlines to let in the most light. Many options are available, including top or side hanging, arched top, and French window fire escape. Liniar casement windows have the look of conventional vertical sliders thanks to the use of imitation sash horns. You can add astragal or Georgian bars for character.

By choosing Liniar uPVC windows, you can permanently put an end to draughty windows because all of our products employ Liniar’s patented, special double-action bubble gasket, which provides a continuous seal even in the corners and keeps your windows weatherproof and leak-free.
