 as insulation because you're not trying to keep the heat on one side and the cold on the other. So I would definitely pull that insulation out, Anna, and I would air out those spaces. And what I would also do is I would spray those walls with a good quality cleaner like Spray and Forget. That will take care of mold, mildew, algae, even dirt that forms on those walls and take that out of the equation as well. So pull the insulation out, spray them down, and then let them air out, and I think that will solve it.
