Wow R 40 is recommended for walls? Is that in particular regions or everywhere? I was looking at using Tiger Foam, and an inch of that with normal R 13 fiber glass, plus what little R value Drywall and the brick outside walls have only get me to about R 20. Normal wall construction down here in Alabama is 2x4, it just about takes a fist fight to get anything thicker. Not sure how i could even get to R 40.
