What is a Casement Window?

Casement WindowA casement window is a window that is hinged on the side. Most casement windows in the United States open outward by using a crank-style handle near the base of the window. In Europe, casement windows often use a lever-style handle to open, and some of the older styles open inward rather than outward.

Benefits of Casement Windows

As noted, casement windows open on hinges, as opposed to sliding window which open by sliding vertically or horizontally along a track, and the hinges are typically along the sides. Casement windows with hinges at the top are also known as awning windows.

One benefit of this style of window is that casement windows create a tighter seal than sliding windows. Not only do they do a better job of keeping rain from leaking into the window, but they also help to insulate the house a little better, keeping warm or cool air from escaping from the home’s interior.

Disadvantages of Casement Windows

There are drawbacks to having casement windows, though. The greatest problem with casement windows is that they are more prone to weather damage, particularly the lever or crank mechanism. With the windows open, these mechanism are often exposed to direct sunlight, heat, rain and dust.

Another disadvantage of casement windows is that the screen is usually on the inside rather than the outside, since the glass window swings outward. As the screens become dirty and corroded, anything that touches them will become soiled as well, according to Home Renovations.
