Hello,

Being a DIYer who noticed several articles about the benefits of sealing rim joists with foam board, I decided to do the same in my house with 2” XPS and great stuff around the cracks. I live in Idaho zone 5a, the house was built in 2006, and additionally has a 1/2” layer of exterior EPS foam under the siding. There are overhangs with gutters all around the house. The foundation is 6-8″ off the grade in most spots. My only concern is I have a large concrete patio in my backyard that is quite high up, with maybe a 2-3″ gap between it and the sill plate.

Do you think this set up will be an issue in terms of bulk water entry and drying potential?
