How do you insulate a 1950’s brick building?
The building is a 1950s apartment building in Denver that we’d like to insulate, with the following wall construction:
Brick exterior, uninsulated wood frame, with plaster on the interior. Additionally, the bathroom currently has a passive vent, and the kitchen has no exhaust fan, so there is a potential for moisture buildup.
According to Cold Climates (p 146), with a vapor semi-impermeable
exterior (brick) and no sheathing insulation, a vapor barrier (or retardant?) would be
required with a vapor permeable interior (plaster).
I’m generally loathe to do a vapor barrier, especially in our dry climate, but I can see the point here, so I’m tempted to recommend a vapor retarding paint.
