Insulate Half of a Basement Wall
I’m in central Maine. I’m going to be insulating my basement walls soon with Thermax. The walls are 6’4″ tall. I’m wondering if I could just insulate the top four feet of the walls because that is where the greatest heat loss occurs. People have also said that this would help things in the event of a leak, but code seems to require it along the entire basement.
I do have one hairline crack in my foundation that does leak a few drops during heavy rains. I’ve used a water proof caulking made to fix these issues and it has helped a lot, but I don’t trust the repair for the lifetime of the house.
Has anyone had experiences with insulating a full vs. the top half of a basement wall.
