Casement windows provide an effortless, elegant look and will complement every type of home. Highly versatile, our casement windows are attached to a frame using one or more hinges; they can open inwards or outwards, and the window can be top hung or side hung.
Top hung casement windows have hinges at the top and they open from the bottom of the window frame, meaning they keep out the rain if you leave a window open. Side hung windows offer excellent ventilation - you can even angle slightly to help catch a breeze - and are easy to open and close.
One of our most popular windows, we tailor these casement windows to your exact specifications and manufacture them in our state of the art factory, before sending them to be installed by our expert engineers. They are available in various frames and colour finishes so you can make sure these casement windows fit the general aesthetic of your home.

The popular choice
Our new and improved casement windows now have more security, better insulation and reduced noise pollution, which means you will spend less on energy bills and you can enjoy a restful, quiet home, no matter where you are.
These casement windows are certified by Secured By Design, part of the Official Police Security Initiative, which seeks to achieve sustainable reductions in crime through high-quality and innovative design.
What is a casement window?
Casement windows are attached to a frame by one or more hinges at the side, which allows it to swing open. You can either opt for single or paired windows to be fitted within one frame and, as they are hinged on the outside, the window swings outwards, letting in maximum light and air.
Although the most common way for a casement window to be attached is through a side hinge, you can choose a top hung (otherwise known as awning casement window) which is hinged at the top – perfect for wet climates as it blocks out the rain. If you’re looking for a casement window for a basement, then bottom hung (hopper windows) might be a more suitable casement window option.
Are casement windows more energy efficient?
Casement windows are fully sealed as an airtight seal is created by the window sash pressing against the frame when closed. This stops the cold outside air from getting in, whilst ensuring that any inside warmth doesn’t escape. As this naturally insulates your home, you won’t need to spend as much on energy bills: your room will feel warmer without even having to turn up the thermostat.
For maximum energy efficiency, casement windows can be made to be double glazed, or even triple glazed. Not only does this mean you spend even less money on heating your home – it also helps to block out noise from outside, perfect for if you live on a busy street.
What is the difference between a casement window and a picture window?
As casement windows are attached to the window frame by a hinge, they can be swung in or out. This makes them a great way to let fresh air in to circulate around the home. Picture windows, on the other hand, don’t open at all, but are better designed to allow for a beautiful panoramic view of your outside space.
Whilst casement windows are typically small, comprising multiple sashes or panes, picture windows are often made up of one large window pane, so that you have little obstruction to your outside view.
Are casement windows safe?
The special hook shaped locks that insert directly into the frame of casement windows make them very difficult to break from the outside. Whilst intruders may try to pry them open, casement windows make this very hard to do, and their multi-locking system adds another element of protection.
At Britannia, our casement windows have the added benefit of being covered by the Official Police Security Initiative, Secured By Design. This means that you can enjoy your casement windows, comfortable in the knowledge that they will keep you and your loved ones safe all year round.
How much do casement windows cost?
The prices of casement windows can vary greatly, meaning there is no single figure of cost. The price of a casement window depends on the material used, the time taken to fit the windows, and how much work needs to be done to fit the window. For example if you were simply replacing an old casement window in an existing frame then this would cost less than installing a new set of casement windows entirely, as this would require added labour.
UPVC casement windows are the cheapest materials to opt for. If you’d prefer a different finish, such as timber or aluminium, this is likely to cost more. For a more accurate measure of cost for casement windows, contact us for a free, no obligation quote.
Are casement windows worth it?
Casement windows are a brilliant way to let in light and air, ensuring your room has a fresh feel to it. Casement windows are also good insulators – the compression seal technology fits snugly to the window sash, creating a tight seal which prevents cold air from getting in and warm air escaping, helping you to save on your energy bills.
Casement windows are also ideal for those who have limited mobility: a crank mechanism opens and closes the window, which requires little effort. In many cases, casement windows can be simply shut and opened with one hand.
