I am trying to renovate a room in an old house (built around 1840), and the previous attempts have damaged the old plaster and lath, so the walls and ceilings have been stripped to the original studs.
How thick of furring strips should I put up, and what materials should I also put behind new drywall? Should I include a moisture guard in addition to the "board" insulation, or sprayed insulation?
Any advice would be appreciated. I have included a representative picture that shows more ceiling than wall, but I'll be replacing both :).
