Casement Windows

  • Designed to add a touch of elegance and class to both contemporary and traditional homes, our casement windows are incredibly versatile. Attached to a frame using one or more hinges on either the top or the side, the window can be opened all the way out for maximum ventilation, or angled slightly to direct a breeze into your home on a hot day. Top hung casement windows open away from the home and keep you safe from the elements if accidently left open.

    Designed to fit the needs of virtually every home and easy to operate, you can see why our casement windows are so popular! Each window is made individually using your choice of colour and finish in our state of the art factory, before sending them to be installed in your home by our experts. If you’d rather the window sat flush in the frame without sticking out from the wall, have a look at our flush casement windows.

Common questions

What is a casement window?

Casement windows are effortlessly elegant, easy to operate and one of the most energy efficient windows out there. They are traditionally hinged at the side of the window frame and are configured to fully open outwards. This allows for maximum ventilation which is particularly beneficial in the summer months as it keeps your home cool. You can choose from either single or double windows fitted within one frame and as they are hinged on the outside, the casement windows swing away from the home creating a light and airy space.

Highly versatile, the casement window can also be top-hung and opened from the bottom which is ideal for protecting your home from the wet weather. They can also be fitted in a basement and hinged from the bottom (otherwise known as hopper windows) which allows for better air circulation and natural light.

Are casement windows more energy efficient?

Casement windows are one of the most energy efficient windows out there. This is due to their air-tight seals that not only keeps the cold air out but the warm air in, ensuring you’re kept nice and cosy in your own home. This will also benefit your energy bills as you’ll feel less inclined to turn up the thermostat during those wet and cold winter months! 

If you’re looking to maximise on your energy efficiency, you can opt for double or triple glazed casement windows. These also help to reduce noise pollution if you live in the city or on a busy road.

What is the difference between a casement window and a picture window?

Casement windows are configured to swing open and are optimised for air ventilation in your home. The overall design is to improve efficiency and its hinges allow for easy opening and closing.

On the other hand, picture windows (also known as fixed windows) don’t open at all and are designed to frame a beautiful view from the house into the garden or beyond.

Whilst casement windows are typically small, comprising multiple sashes or panes, a picture window has a large glass area that allows natural light to enter almost unobstructed. 

Are casement windows safe?

Casement windows are a safe option for your home. Their special hook-shaped locks are inserted directly into the frame, making it very difficult to break from the outside. When closed, the frame is tightly sealed adding extra strength to the casement window. This makes ithe windows extremely difficult to force open. Their multi-locking system also adds another element of protection. 

At Britannia, we’ve taken further measures to ensure our casement windows are highly secure. The windows are covered by the Official Police Security Initiative , so that you can enjoy spending time with your loved ones knowing your casement windows are keeping you safe. 

How much do casement windows cost?

The cost of a casement window depends on a number of factors and can vary greatly. The size, material and time it takes to fit the window can all play a part in the final cost. Another element to consider is the amount of work that will be required in order to fit the window. If you’re simply wanting to get a replacement for an old casement window in an existing frame, then this would cost less than installing a brand new set entirely. 

If you’re looking for the cheapest option, then uPVC casement windows will be more budget-friendly than materials such as timber or aluminium – and they last for decades! For a more accurate measure of cost, get in touch for a free, no strings-attached quote.
