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.

Developed exclusively with leading lock experts, Yale, GrabLock is our most innovative and secure lock yet, with 3 times the locking surface area of a standard, multi-point or shoot-bolt window lock. It creates a virtually unbreakable bond between the frame and the sash offering you the best in home security and the confidence of feeling safe in your home.

Everest uPVC casement windows not only look stylish, but with new GrabLock, our strongest and most secure lock ever, you can be reassured your home is offered the highest level of protection and making you feel secure in your home.
Sometimes, there’s simply nothing to match the natural beauty of wood. Everest offer a wide variety of casement windows in both Softwood (European Redwood) and Hardwood (Red Grandis) that bring a unique elegance and natural warmth to your home.

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.
Everest double glazing windows are made bespoke for you in a wide range of options and colours.
A beautiful range of colours and stains, including uPVC woodgrain finishes, which look like real wood, but without the maintenance. Plus, dual colours with white inside and a second shade on the exterior, in-keeping with both the character of your property and inside décor.

Everest A+ double and A++ triple glazed windows are highly energy-efficient, keeping your home warmer and helping reduce energy bills. The multi-chamber profile prevents heat escaping and Low-E glass reflects heat back into your home, while Argon gas between the window panes, blocks out cold air to eliminate draughts.
Everest windows are tested to the latest British Security Standards and for added peace of mind are also 'Secured by Design', the official Police Security Initiative. Everest uPVC casement windows can be fitted with GrabLock, developed with lock experts Yale and with over three times the locking surface area of standard multi-point locks, it is our most secure lock yet.
