Casement windows are hinged at the sides and usually open outwards (English design), though inward opening (French design) is also available.

The English mode of operation on a casement window is the type that will be most often be purchased and installed. This is because the majority of both manufacturers and homeowners consider the outwardly opening style to be far better as it brings the benefits of superior ventilation. If the window sashes swing open outwards they can be used to catch any passing breeze and so direct the cooling airflow into the home.

Casement style windows can be employed either individually or in combination, and swing open via a crank handle. This means a casement style is a popular window choice for positioning over the kitchen sink. Other types of window would be difficult to reach and operate here.

The Hinge Is The Thing

The casement style of window can be either single or double, with screens on the interior. Single casements are usually best for openings which are taller than they are wide. The double casement type of window is more of a squarer shape than the single style. It has hinges on either side of the frame and both sashes will swing open.

The casement style is becoming more popular all the time in new homes, as well as proving to be the choice of many replacement windows. The fact that these windows can often open up to 90 degrees, and yet still give excellent security once closed and locked helps in this fact.

Hinged casement windows are usually more costly than some other window types, but can help to reduce energy costs because they are better sealed.
