Dense packed cellulose inside foam for basement insulation?
I plan to insulate my now uninsulated poured concrete basement walls. I think I have a pretty good idea of how it should be done using XPS on walls and floors, wood framing inside the foam and with further insulation between the studs,, with a code compliant fire "retardant' cover like drywall. I base my plans on research here, at Fine Home building, and at Building Science Corp.
My question is whether it would be okay to use dense packed cellulose between the studs? I can't seem to find a good answer to this question anywhere. Obviously, there are potential issues with water in a basement but from what I've read, the ability of cellulose to absorb and then release water to/from the air is seen as an advantage of its use. I know I could use fiberglass or a mineral-based insulation but I'd prefer to use cellulose as long as it won't cause problems.
