Insulating / fixing insulation on a soft brick building
After receiving informal advice from a supposed professional, we have discovered that we insulated our 1890’s Iowa soft brick building in, probably, the worst manner possible – a vapor barrier between the brick and stud wall, batting between the studs, and drywall. Luckily, we discovered the problem before there was significant moisture accumulation but we have to remedy the situation before it is further compromised.
What are our options? We have been variously advised to – 1. tear out the drywall, batting, vapor barrier, and reinsulate with batting with the vapor barrier on the drywall side; 2. those same steps except insulate with spray in foam; 3. retain current system and add a second vapor barrier on the drywall side of the studs; 4. use a special paint that acts as a vapor barrier.
I would appreciate any assistance before we rip the walls apart.
