French casement
Also known as: French door, French window, casement door
Quick Summary
A French casement, also known as a French window, is a type of casement window that typically reaches the floor and opens inward from the middle. Unlike other casement windows that may open outward, French casements commonly feature two meeting leaves that open inward. This design requires precise craftsmanship to ensure weatherproofing. In the United States, French casements were often adapted as a means of access to balconies and porches, leading to their designation as French windows, French doors, or casement doors.12
