A casement window is simply a side-hinged window but it’s Britain's most popular window so we offer it in all kinds of sizes and other options. Here we helped the customer select a range of white, double-glazed casement windows with Georgian bars and both top and side opening for ventilation. Beautiful – and practical.

Here we fitted a top hung sash, allowing for safe ventilation but maintaining the perfect symmetry of the window. The handle was selected by the customer to be at the bottom of the window rather than side mounted to make it easier to reach across a work surface.
This picture is a great example of how a modern window can fit sympathetically into a Victorian Cottage. It fades seamlessly into the background and doesn’t detract from the character of a lovely period home.
It's the little things that make a big difference. For example, the Georgian bars have a white gasket that blends invisibly into the bar itself. Our window handles are all made of metal to give a wonderful solid feel in the hand and along with all our hardware come in a range of finishes to complement your home.

Project: Woodside HouseStyled by: Ann BroadPhotographer: Colin Poole
Wood is a natural retainer of heat, which gives our timber casement windows a head start. But we give a further boost, thanks to our A rated double glazing. It comes complete with Low E internal glass, 20mm gaps and advanced weather-resistant seals which always return to their original position for a tight fit.
Aluminium casement windows give you a wonderful modern look and slim profile thanks to the great strength of the metal. Regular sight lines are built in as standard, so each window looks the same, regardless of whether it opens or is fixed. They also offer low maintenance and a wide choice of colours and glazing.
Project: Tenterden House
Up close, the elegance of the slim profile and the even sight lines becomes evident. Yet the narrowness of the design still allows for the 20mm gap between the glazing, and the multi-point locking system is designed to exceed British Standards.
Our double glazing casement windows are available in uPVC, wood or aluminium.
Our bestselling windows are highly secure, energy-efficient and virtually maintenance free as uPVC will never rot, rust or flake. With A++ rated triple glazing and GrabLock fitted, you get our most thermally efficient and secure window ever.
