I have an 80 year old concrete block foundation house. I have fixed drainage issues and the basement now seems to be dry (no musty smell, no standing water, dehimidifier reads about 45).
I am planning to begin finishing, so I want to insullate the space. And I have heard that foam board against the block walls in the way to go.
I guess my biggest fear is putting up the insullation and then over time, if there's tiny amounts of mousture that get though the walls, the moisture is trapped against the blocks causing the foundation to grow mold. It almost seems that it would better to leave the space as open as possible for better light and airflow. Any thoughts?
