Jalousie Window Replacement

What Are Jalousie Windows?

Jalousie windows are made of glass slats that fold open and closed similar to a shutter, allowing you to maximize ventilation. Like an awning window, their slats help repel rain and keep the weather out, allowing you to bring in cool air even during rainy days without soaking the floors. A popular mid-century modern choice, some homeowners are opting for the window style in their homes for their ventilation and aesthetic. Jalousie Windows are comprised of several slats of glass or other materials, which can be opened and closed with the turn of a crank. They are known for their signature appearance and ventilation. 

How Do Jalousie Windows Work?

Jalousie windows’ horizontal slats are layered on top of one another, similar to shingles or siding. The top of the bottom slat is covered by the bottom of the slat above it and the cycle continues all the way up. A crank opens the slats. As the crank is turned, the bottom of the hinged slats tips up and out creating an opening. Most can become fully horizontal creating a nearly unobstructed view of the outdoors.

Most of these window types make use of glass panels, especially the modern options, but some use aluminum panes, or other solid materials to create a more durable window. These solid panes can still both ventilate and create a view because of how they open.
