Casement Windows


A casement window (also referred to as a crank-out window) has a single sash that opens outward on a vertical axis by rotating a crank that is attached to the sash with heavy duty hinges. The hinges can open the sash to a full 90 degrees allowing for easy cleaning from inside the home. A multipoint locking system closes the unit tightly from a single lever. The casement is the most energy efficient of all operable window styles. Casements may be joined together into double, triple or quadruple units.

Hard-to-reach areas like over a kitchen sink or in a projecting window like a bow or bay are excellent locations to consider installing a casement window. The single crank operator can open and close the window with ease. A casement window will allow more light and visibility than other styles.
