    Question Insulating Crawl Space

    I have a thirty year old house located in East Tennesse. The previous owner(s) insulated the crawl space. The HVAC ducts run in the crawl space and are insulated. I started to replace the bats that are falling apart. However before I go any further, what is the best way to handle the rim joist?

    Use the best insulation available, Closed Cell Spray Foam. R-7 Per inch.
