British Made

HL Plastics' manufacturing facility is based in the heart of the UK in Derbyshire and extrudes all of the lead-free PVC that Liniar's French windows are made from.

Boasting the largest uPVC mixing plant in Britain.

Energy Savings

Liniar French windows are capable of achieving WER (Window Energy Ratings) A+ with cost effective double glazing and a U-value as low as 0.8 W/m²K with triple glazing - delivering high energy savings.

Advanced Technology 

Designed completely from scratch in 2007, Liniar's multi-chambered uPVC French window profile is far more technically advanced than the

majority of uPVC window systems on the UK market and are built for modern day.

100% Lead Free

In advance of legislation, Liniar French windows have always been 100% lead-free- better for the environment and better for you and your family. You no longer have lead in your petrol or paint, why choose frames containing lead?
