I own a site work contracting business and am keeping some of my laborers busy this winter. I have them finishing my basement. I installed 1″ XPS against the foundation then framed and installed unfaced batts between the 2×4’s. However as you can see, one of they guys took the lazy way out and didn’t cut and piece directly to the concrete where my foundation steps back. Is this a big deal? I can take the wall down, but that would be a huge hassle. I was thinking of using some Good stuff spray foam to fill in the gap between the foundation and the XPS. Any thoughts?
