Rim joist foam and termites
I’m not sure if this would fit better ‘Energy Efficiency and Durability’ category, but I have a few questions about using foam to insulate rim joists. From an air-sealing and thermal performance perspective foam seems the clear choice. I’ve read Martin’s FHB article and spray foam and cut-and-cobble approaches make sense.
But what should be left exposed for termite inspections? Can the sill plate be covered, as in the picture below, if the top few inches of the vertical wall are left exposed? I have CMU walls and would like to seal the hollow cores, so this approach is ideal if it is sensible in termite-prone areas.
