Jalousie windows are an old window style with louvered glass panes. They allow for plenty of ventilation into the home; however, these windows aren't very secure or energy efficient so they are often replaced. It is not easy to find old jalousie windows for replacement, so new, sliding windows make a good alternative. These windows are harder to break into and are much more energy efficient.

Measure the window with a measuring tape at several points to get the height and width. Order your new sliding window using the smallest measurements if there are any variables.
Remove the jalousie window by opening the glass panels and unscrewing the metal screws that are secured in the frame. Support the window as you work so it remains stable as each screw comes out. Carefully remove the window from the frame.
Clean the window opening with a vacuum.
Lift the new sliding window up into the frame with the help of an assistant. If the window is large, remove one of the sliding panes by positioning it so it is halfway open and lifting it up and out. This makes the window lighter.
Ensure the window is level with a spirit level.
Create pilot holes by drilling through each of the holes along the rim of the window. Use a masonry drill bit if you are drilling into concrete or brick. Make the holes as deep as the screws you are using.
Attach the window to the house using long anchor screws. Use concrete anchor screws for masonry and wood anchors for wood houses.
Fill large gaps by pushing backer rod into the openings with your fingers. Cut to fit with a utility knife.
Apply painter's tape on the inside around the gap's to keep sealant from oozing into the home.
Insert the nozzle of a foam sealant can into the outside crack and fill the crack with layers of sealant until the foam is almost level with the crack. Allow the foam to expand so it fills the crack completely.
Tape around the edges of the exterior window frame with painter's tape. Cover the outside edge of the window with exterior window-door caulk. Smooth the caulk with a damp finger.
