Jalousie windows are a rather unique window option that can often be found in warmer climates. This is because jalousie windows are made like a glass shutter that can easily be opened or closed to allow a tremendous amount of air in.

Replacing Jalousie Windows

A jalousie window is also sometimes referred to as a louvered window. It is made of glass slats that are set within metal clips as part of a panel. The panels of glass slats can be manually rotated so that they open or close like a shutter. In this way, a homeowner can determine how much ventilation or light to allow in through the window.

Jalousie windows are primarily found in warmer climates or in tropical locales. They are often used in areas that are not serviced by heat or air conditioning, and are sometimes found in breezeways or porch areas. Since the panels of glass slats can be selectively opened or closed as needed to allow for ventilation, they are a great option for homes that have no air conditioning or in which air conditioning is very expensive. This is especially true of homes near an ocean or other location that can take advantage of cooling breezes flowing through the windows to cool off the home. For this reason, jalousie windows are often found in tropical areas and were typically used in warm climates before the popularity of air conditioning grew.

The largest benefit to these windows may also be their largest drawback. Their ability to open and close like a shutter and allow a great deal of ventilation to flow into a home is their biggest benefit, but this same design element can also be its biggest drawback. Due to the design of the window, they are almost impossible to seal. Therefore, these windows are not very energy efficient and are not recommended in cold weather climates or anywhere that is subject to extreme weather. Air easily penetrates through the slats and along the hinges on the sides of the windows even when the window is closed.

Another drawback to jalousie windows is that they do not offer a great deal of security. Just as the individual slats cannot be sealed against air loss, the lack of a sealed window makes them an easy target to gain entry into a home. Some building codes do not even allow jalousie windows to be installed due to their lack of energy efficiency and security.

Jalousie windows are a very unique window style. They have a definite place in certain home types and in specific locations, but they are not suitable for all types of climates and all types of homes.

  1. Comments What I am attempting to do now is to take the area above each door (which is currently a solid glass window screwed into the frame and measures 66 ½ inches wide by 9 ¼ inches high) and to get a jalousie type window that has retractable glass and the ability to put in a screen (for ventilation) during the summer and a window in the fall for when the winter sets in. It is a Craftbuilt custom made room, but they do not have that type of product (they sell a solar shade). I can either have them installed or install them myself. It could be a single piece of glass if the 9 ¼ inch opening does not allow for more than one piece of glass. There are five (5) doors and I need a minimum of two (2) windows and all five (5) if the price is right. The room was shaded for years by a neighbor’s trees and now those trees are gone. When we are not home and the room is locked up (for obvious safety reasons), the temperature can exceed 105 degrees as it gets sun all afternoon. As such, nothing can be left on the porch and no one will enter the room until after the sun goes down (which kind of defeats the reason why we have the room in the first place (to be used). If the windows are not an option, we have been looking at opening skylight windows, but because of the potential “leak” from these windows, I would really like to go to the jalousie window.
