What is a Jalousie Window?
Jalousie or louvered windows resemble window shades or stacked roof tiles in their appearance. Glass is typically used in the manufacturing of these windows. The clear glass panels are layered on top of one another like roof shingles. Several parallel slats, or louvers, are set in the window frame to form a jalousie window. These glass slats are movable which allows more air to enter the room. A hand crank or knob is installed to operate the window slats. The glass panels also provide a clear view of the outside space.
Similar to a Venetian blind, the horizontal slats of a jalousie glass window are stacked. These slats are operated by a crank and can be opened or closed to control air passage. When closed, the slats overlap to assist in establishing a seal. These windows are mostly used in closed spaces like sunrooms and covered porches, where proper ventilation could be hard to achieve. Vintage jalousie windows also feature aluminum or even wood slats. However, glass slats are more common now.
