Preventing damage from condensation on wooden roof: questions and opinions?
Hi everyone, im working on restoring a 77 GMC motorhome and had noticed the mylar bubble foam that we had used looks like it's becoming opaque in some spots, this is only after having been for a few months in some spots, and i would think it was just where tape peeled the outside but some of its patterning of deterioration makes me think otherwise. We have roughly 1/8" thick ceiling panels, painted with Kilz, a layer of the foil, and in some spots styrofoam but shaved for an airgap, and then the roof and rails are aluminum.We are wondering if anyone has had similar issues as well as if anyone has had any experience with either the mylar foil, or any of the spray on condensation prevention methods like No Sweat. Thank you!
