Old brick with closed-cell foam on interior - Exterior paint?
I have read a considerable amount about the challenges of insulating brick homes. As I am in an historic district, interior insulation is my only option. From what I have read, closed cell foam is my best bet.
My question is how to best handle bulk water on the exterior of the home. It is a rowhouse with zero overhangs. Presently the front of the house is painted and the rear is exposed brick.
In my mind, I would want to ensure that the exterior of the brick is painted with a vapor barrier paint, thereby reducing the possibility of vapor and liquid coming into the brick structure from the outside. With the closed cell on the inside, there should be little vapor getting into the structure from the interior. Is that correct?
Location is in DC, mixed humid zone 4.
