Is the Airtight Drywall Approach safe to use in a basement?
I’ve looked at several BSC basement insulation recommendations, and they all use foam next to the concrete wall…looks great, but I don’t like foam.
Would a wood stud wall, physically separated from the cement, insulated with fiberglass, rockwool, or even cellulose, detailed according to the ADA, and painted with something vapor permeable be scientifically sound?
My only concern is if the basement were left unheated (zone 5) for the winter, setting up a possible condensation problem on the backside of the drywall where relative humidity and warmth might be a little higher than the basement interior.
Thanks for your help,
