What is a Casement Window?
Casement Windows are an attractive addition to any home, providing unparalleled ventilation and ease of operation. Commonly used in bathrooms or kitchens because of their ability to increase airflow, casement windows are hinged along one side. The main difference between casement and awning windows is the direction which they open, as awning windows are hinged along the top of the sash. With the simple turn of a handle, the supporting arm opens and closes casement windows to either the left or right. Casement windows conveniently open to 90 degrees, allowing for easy cleaning from inside or outside your home. These windows also feature an excellent seal, which makes them one of the most energy efficient options on the market.
