Install a Jalousie Window
A jalousie window, or a louvered window, has parallel glass that opens and shuts in unison. Using a crank mechanism, they help the air flow through the room they're used in. They are most commonly used on porches.
Step 1: Removing the Old Window
Before you install your jalousie window, you have to remove the old window. Use a pry bar or a hammer and a chisel to remove the nails, starting with the trim. Scrape away any caulk. Remove the old flashing and eventually remove the casing of the window and the window itself. If the old window is still in good shape, you might be able to sell it.
Step 2: Cleaning the Area
Scrape any existing debris and caulk from the area where the window used to be. Make a solution of bleach and water and put it in a spray bottle. Clean the area thoroughly to remove any dirt and dust that has built up over the years. Use a spray bottle to minimize the amount of moisture you put on the wood.
Step 3: Readjusting the Rough Frame
If you need to make any adjustments in the size of the old window frame, you should do so now. Hopefully, your jalousie window is similar in size to the old window that was in the frame, so all you'll need are shims to fit everything in tightly.
Step 4: Adding the Flashing
From the outside of the house, peel back the siding to reveal the window frame. Cut pieces of flashing to go around the perimeter of the window, leaving an extra half an inch on each side. Slide the flashing behind the siding and cut in the corners to fold and staple it to the inside. A thin layer of sealant will help to keep out any extra moisture. Use goggles and gloves when cutting the flashing.
Step 5: Installing the Jalousie Window
Place your shims on the bottom of the window frame before putting the jalousie window in place. Once the window is in place, nail in one of the top corners to hold it in place. Make sure the window is level before nailing around the rest of the outside trim. Caulk the gaps between the trim and the frame.
Step 6: Finishing the Jalousie Window
Go back inside the house and shim the sides and bottom of the jalousie window until it is completely level. Cut the shims flush with the wall, and make sure the jalousie window works properly and all the sections open and close at the same time. Use finishing nails to completely nail the window into place, and use a nail set to nail them all the way in. Wood putty can be used in the holes left over.
