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.

Frequently Asked Questions
Take a look at some of the questions previous customers have asked regarding our casement windows. If there’s something we haven’t covered, contact us online or over the phone to talk to our expert team today.
Are casement windows worth it?
They are a brilliant way to let in light and air, ensuring your room has a fresh feel to it. Our double glazed casement windows are also good insulators, as 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. This helps 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.
How energy efficient are these windows?
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 the thermostat.
For maximum energy efficiency, casement windows can be double or even triple glazed. Not only does this mean you spend even less money on heating your home.
How expensive are casement windows?
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.

What is a casement window?
Casement windows are one of our most versatile window designs. The window sash is attached to the outer frame with hinges that are hidden in a euro groove – this means they cannot be seen from the outside. You can opt for single windows, paired windows or any variety of casement windows within the same frame. Casement windows open outwards and are protected from sudden winds with friction hinges.
Although the most common way for a casement window to open is using side hinges, you can also choose top-hung casement windows. Still unsure? Check out our other window styles!
How secure are they?
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.
Great job of our new front door. They couldn’t have been more helpful and even fitted earlier than originally planned. Also gave great aftercare advice and at a very reasonable price! Would 100% recommend.
Cannot recommend Britannia Windows enough! Joe & Keith, the installers were great – explained what was to be done, showed me everything I needed to know upon completion, very considerate & tidied up really nicely. Very friendly guys who are an asset to the team!!
I LOVE my new windows & door. Such an improvement.
We have been extremely pleased with Britannia’s service. From the initial quote through to installation they were great and really easy to communicate with. We had our conservatory roof replaced and they were by far the least pushy and most competitive in terms of pricing.
We can definitely recommend their services and will likely be returning again soon for a new front door!
Fantastic job from initial phone call through to final tidy-up.
Britannia provided great advice before purchasing my new windows and fitted them to a high standard being punctual and polite throughout.
No request was a problem and I will definitely be using them again and would recommend to friends and family.
Wow a fantastic job by both sales team and fitting team.
Sam provided excellent service and answered any questions that we had. Luke, Dave, Keith and Joe did a fab job at fitting the windows and doors. Never having had anything like this done before I was a little nervous but the guys were clean and tidy and the outcome is amazing.
Would highly recommend.
