One of the big benefits of casement windows is their versatility, they can be made in a variety of sizes, as a stand-alone window or used with different window styles, such as picture windows to fill a larger opening. This means that casement windows can be used pretty much in any room in your home. The only time when casement windows are not a good fit, is when you do not have space on the exterior of your home for the window to open up. For example, if you have large bushes or trees in front of your window.
