 Jalousie Window
A jalouise window, also known as a louvre window, is made with large movable horizontal slats/louvres, similar to overbuilt blinds, which are built into a frame. The slats rest against each other when the window is closed and separate when the window is open, allowing air to circulate into the room. Replacement jalousie windows are engineered to provide a slim profile which can compliment either a modern or traditional home design.
The slats are opened and closed with a lever or crank which sits on the side of the window sash. The lever or crank moves the housing on either end of the frame to which causes the slats to open or close by as they move upwards or downwards.
Jalousie replacement windows are available with clear glass panels which admit light into the room. Jalousie windows may also be ordered with frosted or tinted privacy glass which provides privacy when the slats are in a closed position.
Jalousie replacement windows may be placed side by side to create an attractive window effect in areas where the rough window opening is a large space. Manufacturers sell jalousie replacement windows as singles, doubles, triples and quadruples.

Jalousie replacement windows are popular window alternatives in mild climates because they allow air to circulate through the room while maintaining an impression of privacy. Homeowners who are renovating a home in an extreme climate will want to consider the replacement jalousie window option carefully since it is not possible to totally seal the openings, either the openings between the slats or the seam along the frame. In such cases, a jalousie window would be an appropriate replacement window option for a porch or sunroom which is not expected to be used when the weather is extremely cold.
In addition, intruders can easily remove slats of a jalousie window to enter through the window. Security experts suggest that a homeowner place a jalousie window in an area which does not offer easy access to the rest of the house -- on the porch or in a sunroom, either of which should have a door that can lock to separate that area from the rest of the house.
Homeowners who install the jalousie replacement window in a secure area which does not need to be heated or cooled can enjoy the fresh breezes and attractive presentation of the window in specific areas. Jalousie windows can remain open during heavy rains since the glass louvers protrude outward and prevent most of the rain from entering in through the windows. The glass louvers open up to a 110° angle which heightens the air flow while, when the louvers are directed downward they can break up the air currents. Jalousie windows can be washed from the inside, a distinct advantage for homeowners who wish to install them on an upper floor
Due to safety and insulation issues, the best place for a replacement jalousie window is in a pool room, sun room or porch which does not need outside climate control such as heating or cooling. In addition, the room should have a door that separates the area from the rest of the house so that, if someone removes the slats and breaks into the jalousie-window room, they won't be able to access other areas of the house.
Homeowners in temperate climates may also want to consider a replacement jalousie window for an upper floor which is safe from break-ins.
