About Jalousie Windows For The Houses
Jalousie windows are made of multiple horizontal panels or louvers of glass and typically found on breezeways, doors and enclosed porches in warm climates, as well as on some mid-Century homes in cool climates. The earliest reference to jalousies dates back to around the 16th century, and the basic design hasn’t changed a lot since, although early jalousie windows were probably made with wooden slats instead of glass ones. The windows are typically manipulated with a crank which moves the housing on either end of the slats, causing them to open up or move down. There are a number of styles of jalousie window. Some are made with clear glass, permitting plenty of light and allowing people to easily see in and out of the window. Others are made with frosted or tinted glass for privacy reasons, creating a more obscured view, and some jalousie windows are also protected with shutters, in case of hurricanes.
There is a big disadvantage to the jalousie window: these windows are basically impossible to seal. Inevitably, air will slip in between the slats, making the area around a jalousie window quite drafty. In climates which are warm year round, like the tropics, this isn’t a problem, but in an area where the winters get very cold, a jalousie window can be a serious liability, because these windows are not very energy efficient.
