What should I do about this sheathing?
Zone 7 house with D log siding. 2×6 walls. Some plywood, some polyiso board for sheathing. The squirrels love to dig in and get to the fluffy pink stuff.
My question is, after 25 years of visqueen, unfaced fiberglass and this resulting in no detrimental effects, at least in this room. Should I just put the same thing back and air seal from the top? Or something else? Seems like the double foil face would be an issue, but that is why I am asking.
Tons of animal issues, as well as questions of installation since the same room was missing 4 feet of insulation over the double window, and making the roof flat instead of cathedral for better insulation and air sealing, are reasons I gutted it.
