My basement is an unfinished poured concrete foundation with the framing exposed at the top of the walls. There is about 12 inches between the top of the concrete walls and the ceiling where paper faced fiberglass insulation has been installed in the stud bays.
To make a long story short we had a mouse problem and little creatures removed the insulation in five of the stud bays and had been living behind the insulation in another. I used a can of expanding foam insulation on the outside of our house to seal up where the mice where getting in and out.
I have a couple of questions about what to do next. Should I put something on the inside and on top of the foundation to further seal it off? Should I get a roll of fiberglass insulation to redo the empty stud bays or use another material? Can I have fiberglass insulation touching ductwork for an upstairs vent or the dryer venting?
Any and all advice would be appreciated.
