What is a Casement Window?
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.
