Installed fiberglass insulation with craft paper backing... mold...
I bought my '81 AS a couple months ago as a project and I'm in the process of a full renovation (my first). The seller, a good metal worker and welder but not a former Airstream owner either, had taken it down to the frame and done a great restoration of the frame. He used rock wool in the floor and fiberglass insulation (with the backing facing the interior) in the walls. He reinstalled the interior skins.
I noticed leaks inside and wet fiberglass insulation and got to work sealing all-the-things on the exterior. I'm replacing the furnace and water heater, and when I pulled them out the insulation in those areas was both wet and had early black stages of black mold.
Now, I'm torn. Perfection wise, it's probably best to pull the interior skins and re-do the insulation without the backing (and solve any more leak issues in the process). This is intended to be our forever trailer after all.
But is that necessary? Or is sealing and maintaining the exterior, running a dehumidifier (I'd planned on that anyway), and proceeding with use of the trailer fine? No mold is evident inside the trailer, and air shouldn't flow from between the walls to the inside of the trailer, right? (the mold would be isolated?)
I think I know the right answer, but trying to come to terms with it. I'd love to get y'all's insight and help in thinking this through.
