The 6 multi-chambered profile is what makes Liniar stand out from the crowd. Designed to be much more thermally effective that previous uPVC systems. Our windows can achieve an A+12 energy rating.

Hand-Finished Process

Liniar’s uPVC window frames are individually hand finished by skilled craftsmen to provide a bespoke and personal finish that puts Liniar ahead of the competition. There are 4 steps to to the unique hand-finishing process.

1. All corners are checked for their appearance and completed by hand to ensure precision  and finish.

2. The outside edges are levelled at the corners to maintain a beautifully square silhouette.

3. To keep every window identical, each corner groove is checked for depth and manually corrected.

4. All apertures are inspected for weld build-up and any protrusion is removed for a tight weather seal.


We are part of the best supply chain in the industry.
