Jasoulie Windows
Jasoulie RV Windows come in a variety of single pane configurations. Some have stationary glass units, and the venting/awning glass panes are horizontal and open out from the bottom all at once when operated.
These frames are either mechanically fastened with screws, through a trim ring, with the wall between the interior trim ring, and the window frame itself, or screw into the exterior wall.
The horizontal awning/venting glass units are either cradled on the sides with metal operators, and raw glass edges on the bottom and/or the top. Others' are circumfrenced by a 'U' gasket, and nested into aluminum channels on all 4 sides.
Functionality
*Window frame is either mechanically fastened to a trim ring on the interior wall and sealed on the back of exterior flange with compression tape, butyl tape, or similar low viscosity sealant -or- the face of the frame is screwed into the exterior wall of the RV with sealed screw holes, and butyl tape or low viscosity sealant behind the face of the frame.
​
*Stationary glass unit(s) are either sealed tight within the exterior channel-with a U-Gasket around the perimeter of the glass - or - sealed directly to the back wall of the channel with adhesive, and a snap in molding around the perimeter to cover the edge of the glass (this snap in molding doesn't provide any properties to seal or bond the stationary glass).
​
*The venting/awning panes are sealed when closed with a weatherstripping on the sash where the awning/venting glass closes against.
​
*When the venting/awning panes are open, they don't open past 90 degrees. This allows the windows to remain open and still deflect water out and away from the interior of the sash and the RV.

Maintenance
-Window glass can be cleaned with soapy water or a non abraisive/non acidic cleaning solution and paper towels.
-Weep holes in the bottom sill can be cleaned with compressed air, compressed air cleaning solution (i.e. 3 in 1 Vent Track Lubricant works), and a pick. These weep holes are in the bottom sill to weep/drain out any condensation accrued and retained water which may have worked its way in through the weather stripping and/or header seals.
*Weep holes get clogged with insects, vegetation debris, and insect nests). Jasoulie windows have the easiest weep holes to clear. Merely vent the panes open and you will have full access to the lower sill.
-Weatherstripping and moldings can be sprayed with rubber conditioner (i.e. 3 in 1 Rubber Seal Conditioner works) and wiped with a paper towel to keep them from dry rotting.
Pros / Cons
-
Jasoulie Windows have been around for decades, with proven characteristics which feature operational functionality and simplicity.
-
Able to open several panes at once to allow fresh air in
-
Able to keep window panes open in light rain without getting direct rainwater into the RV
-
Jasoulie windows come in a number of configurations which offer stationary panes as transoms and sidelites to the horizontal venting panes. Many options allow for a good bit of natural sunlight.
-
Easy to maintain the weatherstripping and seals, and replace if necessary (many suppliers offer parts for jasoulie windows).
-
Interior side of the venting glass panes can be difficult to clean, even when open.
-
The screens can be hard to remove and reinstall into the interior sill lip.
-
Even though the horizontal venting panes allow a good amount of fresh air flow- Individually, the panes do not open very far which is less desireable for some RV'ers.
-
There is a lot of metal hardware (subframes, horizontal and vertical extrusions, cranks assemblies)- which can clutter views.
