How to Buy Jalousie Replacement Windows

Jalousie windows are a type of mechanized window treatment that resembles the common, indoor plastic blinds often found in offices and apartments. Horizontal, parallel slats of glass, wood or acrylic are set on a track within the window frame, and are operated in unison via a rotating crank device. Popular in the deep South and other climates with high humidity and mild winters, jalousie windows--sometimes called "louvered" windows--are ideal for covered porches and structures that do not require airtight protection from the elements. From a decorative perspective, jalousie windows add a casual, retro flair to your home; the popularity of this window design reached its peak in the 1950s and '60s, and is still commonly found in dwellings located on the Hawaiian Islands. If you already have jalousie windows installed in your home, update the look by switching from glass to acrylic or wooden slats, or by changing the color of the panes; minor adjustments to preexisting treatments will save you time, effort and money.

It is possible that you will have to have your windows shipped from a warehouse, risking damage and incurring shipping costs. It's recommended that you repair individual slats or parts, rather than replacing entire treatments. Consider also your home security; louvered panes can be easily removed from the outside.
