Insulating kneewalls in Michigan
I want to remove all drywall to studs and reinsulatate walls and ceilings properly. I’ve read many of the questions and responses. My questions: 1. On the drywall side, is it necessary to add a vapor barrier? 2. Would insulation be faced or unfaced? 3. For additional cost, would rock wool be worth it? 4. On ceiling, batt insulation between joists then blown in cellulose? 5. Between rafters above knee walks, a one or two inch space with osb or foam board be good for ventilation then rock wool or fiberglass batt? 6. Back side of kneewalls. Would 1/2″ osb be adequate. Would it conduct cold to insulation? 7. I would cut 2x material to put between floor joists and seal with spray foam. Thank you for responding. Great site by the way.
