What is a Jalousie Window?   
It’s common for older homes to have windows split horizontal sections which open and close at an angle. While they aren’t as popular today as they used to be, these jalousie windows are effective at ventilating a home, offering benefits that modern homeowners in warmer climates will appreciate, and in modern prefabricated steel structure houses, this old but reliable life-partner came to life with its constant perfrmance to our daily life. 

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 tip 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 the way in which they open.
 

Enhanced Airflow with Jalousies
Compared to double-hung or single-hung windows, you can get more airflow through jalousie windows by making use of the entire opening. With single or double hung windows you can only have half the space open at one time.
 

Simple Jalousie Window Glass Repairs
Jalousie window slats are easy to repair and cost effective because you only have to replace the damaged slat. Traditional windows usually require full pane replacement, which is more costly. When a section of your jalousie window breaks, you unhook that section and put a new one in. This easy maintenance is one of the main reasons people favored these windows decades ago when glass was less durable and more prone to breaking.
 

Versatile Decorating Options
Yet another benefit of jalousie windows is that the slats are replaceable with different types of glass and even non-glass materials like aluminum or wood. If you decide that you want to transform your window into a shutter, or a stylish frosted privacy window you can do so easily. Simply unhook the sections and slide out the current glass slats and replace them with same-size replacements. It’s much easier to change the look and function of this type of window than a full-pane type of window.
