Cellulose insulation in basement?
We are putting a granny suite in our walk-out basement (newly constructed house) and are thinking of insulating the knee walls (wood framed walls between the top of the stepped foundation and first floor deck) and the ceiling with cellulose. The cellulose in the ceiling would butt up against closed cell spray foam at the rim joist. The floor above will be concrete (radiant heating).
Would anyone recommend against using cellulose in this situation? Are there issues with using cellulose in the basement knee walls? I have read recommendations against insulating a basement ceiling, but we need the insulation for noise reduction and it would also help the first floor slab from radiating heat downward. The basement slab is also radiant.
The house is located in zone 7 (cold winters, warm humid summers)
