Missing tar paper on brick exterior/wood stud house?
I own a 1922 brick bungalow in Illinois. The main floor has one wythe of brick on the exterior, then an 1 1/2″ air gap, then wood stud walls. I want to drywall the ceiling and walls in one room — the previous homeowners removed the original plaster and lath and added fiberglass insulation and drywall, which I removed. There is tar paper attached to the studs only on the bottom third of the wall (photo attached). After reading through several other posts here, I’ve decided not to insulate this room at all because I don’t want to somehow damage the brick over time (I’m also on a budget and doing many other repairs to the house that are more important). I was just going to drywall over the studs as is, but now I’m wondering if I should somehow correct the lack of tar paper on the rest of the wall.
When I removed the fiberglass insulation and drywall, which I would guess had been there for minimum 20 years, probably more like 30, nothing appeared to be wet or moldy. This house has 2′ overhangs everywhere and the brick seems to be in relatively good shape.
Would it be a problem to drywall over the studs as is, or is there a chance of a moisture problem? What might I do to correct that? Thanks for any advice.
