Information about our Casement windows

A casement window has a hinged sash that swings in or out like a door. Crank-style or lever-style handles are used to open the sash. An additional handle locks the sash in the closed position.

The handle mechanism on casement windows is easy to operate and is usually located low on the window, making the casement window an ideal window to place above cabinets, countertops, or places that are slightly more difficult to reach.
Casements are appealing both in new contemporary homes and in older style Prairie and Tudor homes. Like other styles of windows, the casement window can be installed as a single unit, or grouped together.
