Insulating a split level attic
I have an attic above my kitchen with 3 interior walls and I am trying to figure out how to insulate it correctly.
Currently the walls facing the bedroom and the entry way have fiberglass insulation.
The floor has cellulose insulation. ~2-3 inches.
The ceiling rafters has ~4" of white fiberglass/denim insulation inside of perforated plastic bags between the ceiling rafters, this appears to be pretty consistent, but I suspect it is leaking a bunch of air.
The roof line is several inches about the existing insulation and connects to the space above living rooms vaulted ceiling.
I am thinking about putting rigid insulation boards below the ceiling to air seal the space, is this a good idea or would it cause problems?
