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.

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.

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!

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.
