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?

I don't understand what you are trying to explain.

Are you saying that no water penetration membrane was used behind the brick on top of the wood sheathing of your home?

Or are you saying there is no vapor retarder on the insulation?

I, too, am a little confused. A vapor barrier is used on the inside of the insulation, not on the outside walls. The point is to prevent moisture from the living spaces from penetrating into the insulation. On the exterior, 'house wrap' is often used to prevent air (wind) penetration into the house. This 'wrap' is waterproof but does allow water vapor to pass thru so the insulation can stay dry. The 'tar paper' barrier you referenced is generally not a good idea since it does not allow trapped water vapor to escape. If you use anything, suggest 'house wrap'.

Sorry for the confusion. They removed the drywall from the floor up about 3 ft. They took out all of the insulation and the gyp board that was there btwn the insulation and the brick. We are going to have to come up with a way to replace the gyp board for that removed section and tie it in to the gyp board that wasn't removed. We didn't know whether to cut the gyp board into sections (to be able to fit it behind the studs) and then try to somehow tape it back together, and to the the gyp board above it, or use something else. This is before we replace the insulation.

I have a similar situation need to replace the sheathing from the inside because it is covered by brick on the outside. If you are still arround, please help me understand how you approached this.
