What is a casement window?

Casement windows have an almost-doorlike outward opening. To gain more access to the outside, simply turn a handle on a crank to slowly open the windows. Casement windows allow you to maximise the window opening by avoiding having a centre mullion, which is the most obvious visual distinction between casement windows and other types of windows. Read on to learn some of the benefits of casement windows:

Provide airflow

Casement windows are made to be fully opened, so you can do so as needed. Other windows, like those that only partially open up or down and are double-hung, do not share this limitation. You can more easily catch breezes if your windows can be completely opened. Additionally, your home will receive a larger volume of airflow as a result of this. Casement windows will be ideal for you if you value using natural breezes to ventilate your home whenever possible. They allow in fresh air while keeping out bugs and debris when used with screens. Casement windows are popular because they allow people to quickly bring in outside air in their kitchens and bathrooms.


For homeowners, saving money is always important. In order to seal the window and prevent energy loss, casement windows can be closed tightly by hand. Casement windows are a good option if you like the idea of paying less for utilities. They will allow you to save more money each year without having to compromise on your desire for a window that can fully open.


Casement windows also have the advantage of complementing other window styles well. This enables you to combine casement windows with other types of windows, including double-hung, picture, and windows with unusual shapes.

How do you choose which window to replace with a casement type? Generally speaking, you should pick a room that could benefit from more airflow and unrestricted access to the outdoors. You might even want to consider having a casement window added to a wall that doesn’t currently have any windows.

Architectural distinct

Many homeowners desire a distinctive yet traditional appearance for their homes. Any type of home can benefit from the elegance and charm that casement windows can add. 


It is very difficult for someone to break into a casement window because they completely close on all sides. Even if someone breaks the glass while attempting to enter your house, it can be difficult to reach inside and turn the crank. As a result, casement windows are highly regarded by people and families who want their windows to be secure as well as beautiful.

So if you’re looking for a window that is energy-efficient, secure, and low-maintenance, double-glazed casement windows are a perfect choice. Contact us today to find out more about our range of double-glazed casement windows, available across Radlett, London, and Hertfordshire.

From the first moment when Arthur came round to advise, measure-up and quote for the job we felt we were in good hands. And his team of installers provided the best service. I always think that the best test is if something needs further attention and in this case they returned promptly to fix a small issue and nothing was too much trouble. Our new doors have transformed the back of our house and we highly recommend this company for work of the highest quality. Thank you Arthur and team!

We got our back and front doors replaced by E&A Windows and we couldn't be happier with the job they did. Erez was so helpful as took the time to come to our home to give us a quote, explaining all our options thoroughly and clearly without being pressuring in the slightest. The quality of both doors was fantastic and Adrian’s installation was fast and completed to a very high standard. He was also very helpful. We would highly recommend E&A Windows and will definitely use them again for any future double glazing needs. Thanks so much!

Very professional service! During my initial consultation, I was fortunate enough to deal with the owner of the company. He visited my property and spent a few hours talking me through design options and his recommendations. His recommendations were very insightful and ensured my build looked elegant and modern while retaining the functionality required for an active family of 4. The build process was equally professional with the construction team arriving when they said, treating my property with respect and cleaning up after they finished each day...something not often done by today's tradesmen. I've recommend this company to my parents.

I have just had new windows installed by E&A Windows and I must say I was very impressed. Arthur the owner of the company was so helpful and supportive throughout the process. I don't know much about windows so was skeptical at first, but I felt at ease very quickly. The guys who came to fit the windows (John, Christie and Peter) were absolute legends. They were extremely friendly and so so helpful, and the respect they gave me, my elderly parents and our home was exceptional. They took care of our home as if it was their own. I have never come across such professionals, not only did they do a fantastic job , but they went well beyond, seemed like nothing was impossible. They were with us only for 3 days but my parents were actually sad to see them go. I would highly recommend them to anyone looking to fit new windows.
