British Made

Bay and bow window frames are made from lead-free uPVC, which is extruded at the HL Plastics manufacturing facility in Derbyshire. Continued investment in the facilities keeps Liniar at the forefront of innovation.

Thermally Efficient

Liniar's multi-chambered uPVC window profile was created in 2007. With the best and latest developments in window engineering technology Liniar's range is far more advanced than the majority of window systems in the UK. 

Cost Effective

The profiles used deliver high energy savings for the home owner at a cost effective price - capable of achieving WER A+12 with cost effective double glazing and a U-value as low as 0.8W/m2K (with triple glazing)

Environmentally Friendly

All elements of Liniar's uPVC bay and bow windows are easily and fully recyclable at the end of their life, making them better for the environment. Liniar bay and bow window frames have always been 100% lead-free,
