Which type of window is hinged on one side and opens like a door?

A casement window is hinged on one side and opens outward, resembling the movement of a door. This design allows for excellent ventilation, as it can be fully opened to create a large opening for airflow. The ability to swing open to the outside makes casement windows ideal for capturing breezes from different directions.

In addition to ventilation, casement windows often provide unobstructed views, as they do not have a center muntin (the vertical bar in the middle of a window) like some other window types. This design enhances the aesthetics of both modern and traditional home styles.

Furthermore, casement windows are easy to operate, typically equipped with a crank mechanism that allows users to open and close them smoothly. This feature also contributes to their energy efficiency since they can be tightly sealed when closed, reducing air leakage.

In contrast, other window types mentioned do not share this specific hinging mechanism or operational characteristics, making the casement window distinct in its functionality and design.
