I have an apartment want to add insulation from the exterior.
It is a block building 1950’s vintage. Walls in the inside are stripped with 3/4 furring strip. Insulated with 3/4″ fiberglass with vapor barrier on inside. Finished inside with plastered walls.
I am thinking of adding foam sheet insulation to the outside of the building. I do not want to trap in moisture and cause mold problems. .
What is the proper way to do this. I do my own work. If anyone can guide me in the right direction I would appreciate it.
