Wet insulation behind chair rail

I'm taking out the metal skins between the windows and the chair rail, and planned to caulk the windows & then rust converter & Rust-Oleum the floors. I was planning to use green board insulation in the walls, floor, ceiling (I'm taking the metal off the ceiling also and will caulk)/patch). Floor needs some hole filling.

ANYWAY I wasn't planning to remove the chair rail portion, but I'm finding wet insulation in there, just as the bottom. I'm wondering if I should address that without removing that part, maybe from outside, or if sealing the windows/roof would be adequate? I don't want to create a mold factory.

Pull out all the wet stuff but don't remove the chair rail.
Spray some rust converter down there if its rusty.

Properly sealing the windows and roof with seam sealer (not silicone) will be key. But also remember that metal tents sweat and the humidity will run down the walls. So whatever you use to insulate make sure its not organic.

Thanks - that's in line with what I was thinking. Working with metal sweating is weird!

Can also be from inherently leaky Skoolie windows.



Yes...they ALL leak until you do something about it.

i fixed a lot of my leaks just by recaulking the windows from the outside.

for the roof and any mounts you put up, get self leveling sealant. cant remember what type of caulk i used for the windows. paintable something or other.


edit; metal sweat can be helped by a thermal break between the framing and your desiered finish.

There are a surprising number of gaps in the window situation!
