Derby Double Glazing’s 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 casement windows the appearance of traditional vertical sliders. To add character you can add astragal bars or Georgian bars.
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.
Choosing uPVC casement windows means you can say goodbye to draughty windows forever – our 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
