What are Jalousie Windows?

Jalousie windows are louver windows made of parallel slats of glass, metal, or wood placed in a frame. A crank opens and closes these slats to regulate air breezes and light entering a room. Jalousie windows have been popular in warmer climates because they effectively ventilate and are distinctly designed.

How Do Jalousie Windows Work?

Jalousie windows function on the principle of opening through tilting slats, allowing airflow. Once you have a crank, all the slats open; thus, the gap between every glass pan is even. This allows fresh air to blow through while keeping the rain out, making it perfect for consistently well-ventilated spaces.

When closed, the slats overlap slightly to protect from weather but don’t seal up as tight as other types of windows, such as double-hung or casement windows.

Benefits of Jalousie Windows

1. Increased Ventilation

Jalousie windows are great for ventilation. If the windows are opened a little, they allow airflow in while keeping the rain out, which makes them superb for tropical or wet conditions.

2. Cost-Effectiveness

The cost of Jalousie windows is much lower compared to other forms. Should one of the glass slats break, you must replace the damaged slat, not change the whole window, and save more money over time.

3. Natural Light and Fresh Air

Jalousie windows allow generous natural light as well as beautiful ventilation. Fully open, they give maximum airflow, useful in areas without air conditioning. If Wi-Fi has good reception, look at Do WiFi Extenders Work.
