Casement Windows

Liniar Casement Windows are often referred to as the ‘ultimate window’. They are stylish, secure and energy efficient, and have proven themselves to be a classic and practical addition to any and all homes that they are installed in.

About the windows

Thermally Efficient

Our casement windows comprise our multi-chambered uPVC profile, which works to trap in pockets of warm air and maintain the warmth in your home. Enjoy A+ rated standards, today.

Less frame, more glass

Ultra-slim sightlines designed into Liniar products allow in maximum natural light – and result in more attractive windows and doors.

British made

Liniar profiles are extruded in Derbyshire at the HL Plastics manufacturing plant, which boasts the largest mixing plant in the UK. Continued investment in the factory and facilities keeps Liniar at the forefront of innovation.

Better for the environment

Liniar frames have always been 100% lead-free, well in advance of legislation. Furthermore, all elements of a Liniar window are fully and easily recyclable at the end of its life.

Beautiful colours

Liniar’s coloured foils give the appearance of woodgrain and won’t peel or scratch off - and the whole Liniar range is available in a wide choice of colours with an easy clean, low maintenance finish.
