Jalousie Window
Definition and meaning of Jalousie Window in real estate.
A jalousie window is a window style composed of parallel glass, acrylic, or wooden slats set in a metal frame that can be tilted open and shut in unison using a crank mechanism.
In more detail
Commonly found in older homes, particularly in warm, tropical regions, these windows are designed to maximize ventilation and airflow. When opened, the slats tilt outward to act as mini-awnings, allowing cool breezes in while keeping rain out. However, jalousie windows have significant drawbacks, including poor energy efficiency due to air leaks between the slats and weak security because the panes can be easily removed.
For these reasons, modern builders rarely install them, and home buyers often replace them with double-hung or casement windows to improve insulation.

Frequently asked questions
Are jalousie windows energy-efficient?
No, jalousie windows are notoriously inefficient because they do not seal tightly, allowing heated or cooled air to escape easily.
Can you repair individual slats on a jalousie window?
Yes, one of the advantages of these windows is that individual broken glass slats can be replaced easily without replacing the entire window unit.
