Casement Windows

Liniar casement windows offer total versatility and remain the most popular choice for homes all over the UK today.

This traditional British uPVC window style offers slim sight lines to let in maximum light. Available in a wide choice of configurations, including top or side hung, arched top, or as a French window fire escape. Adding mock sash horns gives Liniar casement windows the appearance of traditional vertical sliders. To add character you can add astragal bars or Georgian bars.

Choosing Liniar uPVC casement windows means you can say goodbye to draughty windows forever – Liniar’s unique, patented double-action bubble gasket, used in all our products, delivers a continuous seal – even in the corners – also keeping your windows weather proof and leak-free.

Benefits

  • British Made

    Liniar casement window frames are made from lead-free PVC, which is extruded in Derbyshire at the HL Plastics extrusion plant. The factory boasts the largest PVC mixing plant in the UK and is one of the largest employers in the region. Continued investment in the facilities keeps Liniar at the forefront of innovation.

  • Thermally Efficient

    The revolutionary profiles used in Liniar casement windows are far more thermally efficient than traditional uPVC window profiles. By removing unnecessary steel reinforcement, instead developing the latest in multi-chambered profile technology, we make sure the heat stays where it belongs – inside the home.

  • Cost Effective

    The profiles used in Liniar casement windows deliver high energy savings for the homeowner at a cost effective price. Liniar uPVC window systems are capable of achieving WER (Windows Energy Ratings) A+12 with cost effective double glazing – and a U-value as low as 0.8 W/m²K (with triple glazing).

  • Environmentally Friendly

    In addition to saving energy costs for homeowners, Liniar casement window frames have always been 100% lead-free, well in advance of legislation – better for you and your family. Furthermore, all elements of Liniar uPVC casement windows are fully and easily recyclable at the end of their life.
