Moisture barrier for brick
We recently had to remove some drywall due to mold. Right now, there is no moisture barrier between the inside of the house and the exterior brick wall. We live in a humid climate and we are trying to decide how to replace the moisture barrier that was removed without having to take out the remaining drywall. We have been told that the felt paper (tar paper) used on roofs can be put in the void, tucked up under the remaining moisture barrier, then put the insulation between the studs, then the drywall. We've been told not to use the foam boards as it doesn't breathe and can actually lead to mold. Any experience with this situation?
