Teardrops n Tiny Travel Trailers

In thinking ahead. How did most of you guys seal/waterproof your windows frames to the foam/canvas body ? I know that RV's use gray butyl tape (which may be costly) , I was thinking of using 100% silicone in the large gun tubes. But these are just my ideas

I am using butyl tape and an bead of waterproof caulk around the outside edge.

I used butyl tape on my clamp ring style windows. I personally do not like the silicone style sealers.

I used a lot of this stuff - http://www.homedepot.com/p/Loctite-9-fl ... /205451965

It's paintable and pretty strong and cleans up with water.

It's about $10 for 30'. I use it in some sealing applications but the fact that the general RV industry uses it for their cranked-out junk should tell you something.

Without a doubt, the best sealants these days are polyurethane based. One problem with silicone is that it adheres poorly to something that has been siliconed before.

My windows have no seals, being wiley windows they float loose in the window frame, and are held shut with foam wedges.
Of course I never shut the windows unless it is a really cool night when camping, the rest of the year the windows are open, and my tear is stored outside year round.

ProFlex RV is what I used. Factory CT builder just used a small bead of silicone around the outside edges of the frame. I did it right when I had to take windows out to insulate the walls.

3M 5200 marine adhesive sealant ... if we ever want to remove them we’ll have to cut them out ...

We Never use anything the RV industry uses , because it’s "DESIGNED TO FAIL “ ... Failure is the basis of their economy ...

I used 5200 to mount the frames and piece of spacer foam. They aren't going anywhere.

On my teardrop I used 3M 4200 under the trim. It is also a marine adhesive sealant but according to 3M it will allow disassembly of parts as compared to the 5200 which is for permanent mounting. The 4200 seems to be pretty permanent though.

For my windows, I used butyl tape, retightened the mounting screws and removed the squeeze out after a month or so, and ran a bead of OSI quad sealant around the perimeter of the windows. I did this instead of using the 4200, in case I ever needed to remove the windows.

I used an old time product called rope caulk. It is a never drying caulk similar to modeling clay. In the summer it is soft enough to get some squeeze out so it is easy to get a waterproof seal. I use it as a bedding compound for the roof vent, windows and hinges. It should be relatively easy to remove said parts for repair or replacement. I don't know if this is the best compound to use but I liked using it.
