Jalousie windows (also called louvered windows) consist of parallel glass slats set in a frame that can be tilted open and closed using a crank mechanism. While once popular in warm climates, many homeowners now replace jalousie windows with more energy-efficient and secure alternatives. Replacement often involves converting to casement, single-hung, or sliding windows.
