Should a Casement Window Replacement Open Left or Right?

Replacing a window involves a lot more decisions than you’d expect. What style of window should you choose? Do you want an awning windows installation or is it better to install a bay window? What kind of trims and finishes would maximize the looks of your new replacement window? If you’re already decided on getting casement windows, one of the most important decisions you’ll face is about its operation.

casement windows open

Casement windows have a unique way of opening and closing. The casement itself usually opens outward, pivoted on its hinges. These hinges can be placed either on the left side or right side of the frame. In some cases, homeowners even choose to place the hinge on the top or bottom side of the window. Let our experts at Renewal by Andersen® of Rapid City show you the right direction your casement window should open.

A Matter of Preference

There really are no hard and fast rules about how your casement window replacement should open. This choice is completely up to you and your preferences. Traditionally, casements are installed to open outward, hinges on the left or right side of the casement, depending on where in the house they are. Furthermore, people also choose hinge placement based on their dominant hand. Right-handed people prefer casements that open to the right, and vice versa.

Air Circulation and Ventilation

On a purely functional perspective, however, experts recommend placing casement windows that open the opposite way on opposite sides of a home. This maximizes ventilation, producing a cross-breeze in a room’s air circulation.


Another way to decide how your home replacement windows should open is by judging how the final product will look. Most homes prefer placing their casements side by side, with opposite opening directions, just like French windows, and maximizing air circulation and daylighting.
