Which Way Should Casement Windows Open?


While there are no clear-cut rules when it comes to determining which direction a casement window should open, there are a number of considerations you need to keep in mind in order to optimize its aesthetics and performance. An exterior remodeling expert goes over them here.

Casement Windows

A Matter of Preference

Whether your casement windows should open to the left or right is up to you. Generally, casements are installed to open outward and are hinged at the side, depending on where in the house they’re placed. Homeowners also often decide on hinge placement based on their dominant hand. If you’re right-handed, for example, it’s more convenient to install casements that open to the right, and vice versa.

Air Circulation

From a functional perspective, experts normally recommend installing casement windows that open the opposite direction on opposite sides of the house. This technique produces a cross-breeze in the room and makes the best use of ventilation. If you’re thinking about tackling window replacement in the near future, make sure to incorporate this optimized method of cooling to prevent mold growth and minimize the need for air conditioning.


Another consideration to make when deciding which direction to open your casement windows is how the final product will look and complement your home. Many houses have casements placed beside each other with opposing opening directions, like French windows, which feature two panels that are side-hung and open either outward or inward. In addition to increased ventilation, this maximizes daylighting and provides an uninterrupted view of the outdoors.
