Casement windows are hinged to allow an outward swing of the window away from the frame and wall. Casement windows typically have a single glass panel that swings open to the outside. These replacement vinyl windows provide an attractive option that maximizes viewing area, but also provides the option to open for airflow and ventilation. Casement windows are similar to Awning windows in that they are both hinged. However, the awning window is hinged at the top and swings upward and out.
