I have been insulating between the joists in my basement (essentially first floor insulation) with fiberglass batts (R-19 in most places). Can I use fiberglass under where the stove sits and touching the chimney? My hearthpad under the stove is R 3.1 (the manual requires 2.5).
Do I need to use rockwool or is fiberglass ok?
