Jalousie Window Restoration

Talk about a contrast in window design! The Hehr windows on my 1958 Overlander are completely different than those found on my 1972 Sovereign, like they were from another planet. This difference is epitomized by the Jalousie windows. The five parallel glass louvers are unique in window design and require a different approach for weather sealing.

While these windows are vintage you can still buy the seals you need from Vintage Trailer Supply. Three seals are required. The top and bottom of the window frame is sealed with a gray colored bulb gasket which cushions the glass and provides a water and an air tight seal. The bulb seal can be difficult to install, but a little WD40 in the track really helped slide it in. The sides of the louvers are cushioned and sealed with a fuzzy strip, again WD40 helps. Finally, the tops of the individual glass louvers are sealed with a clear rubber seal which provides a thermal and water barrier. Removing the screen in the back and installing these from the inside really speeds things up, especially the top louver.

Though not technically a seal, the retainer disks in each individual louver should be replaced as well. Some of mine were missing and those which were still installed were brick hard. All should be replaced. These are cut to size and are simply wedged into place to keep the glass tight in the louver. These can also be purchased at Vintage Trailer Supply.

Aside from the standard Jalousie window by the door, my Overlander also has a Jalousie window in the front. I've never seen this before in an Airstream. The make of this front window is newer from the side Jalousie, so it appears to be a retrofit by the original owner.
