Brief Overview of Casement Window
A casement window is a classic and highly functional window style hinged on one side, allowing it to swing outward (most common) or inward like a door. It is operated by a manual crank or lever handle that drives a geared mechanism, offering precise control over ventilation. When fully opened, it provides 100% unobstructed airflow, making it exceptionally efficient for catching and directing breezes. Its design also offers superior sealing when closed, as the sash presses firmly against the frame, enhancing weather-tightness and energy efficiency. With no central rail obstructing the view, it maximizes glass area for a clearer outlook. Commonly used in both traditional and contemporary architecture, it is valued for its versatility, excellent ventilation control, and clean aesthetic lines.
