What Is a Jalousie Window?
- While the history of slatted windows may be traced back to the Middle Ages, modern jalousie windows enjoyed their highest level of usage in the 1950s and 1960s. Jalousie windows were commonly used in Florida, Southern California and areas of the Deep South prior to air conditioning. The word "jalousie" derives from the French word "jaloux," meaning jealousy. In relation to the name of the window, this could refer to the basic construction, which allows the person inside to look out, while those outside cannot see in.
- Unlike traditional windows that open from the bottom, the louvered design of the jalousie windows allows the entire window to be opened, increasing the airflow throughout a home. This feature not only cools the home, it also aids in dispersing cooking odors from a kitchen. The downward slant of the panels allows windows to remain opening during rain without water entering the home. The variety of styles available, including colored and frosted glass, adds to the versatility of jalousie windows. This feature makes them an attractive choice for bathrooms. The design offers privacy while reducing steam. Individual panels of jalousie windows are easily replaceable. If a single pane is broken, there is no need to replace the entire window.
- The overlapping design makes it difficult to seal the window. These gaps allow heat loss, making them a questionable choice in colder climates. Modern technology has improved this problem, but it may be a consideration when choosing replacement windows for a home. Ironically, one of the advantages of the jalousie window may also be considered a disadvantage. The ease of removing individual panes may be a security risk. It is possible for an intruder to remove panels from the outside, allowing access to the home. Fire safety may also be a concern. While the panes are removable, during an emergency when time is critical, the windows may hinder the escape of an inhabitant inside the home or the entrance of rescue personnel. Due to these issues, some communities ban the use of jalousie windows. Check your local building codes before installing.
- Jalousie windows are relatively easy to maintain. Parts for jalousie windows, including the window louvres, frame and the operation crank are readily available. Washing a jalousie window is more time-consuming than most standard windows. It is possible to power wash the windows, taking care to point the hose downward so water does not enter the home. It's possible to remove panels and wash them individually.
