Spray foam

[NoWiser]

I’ve priced it out numerous times. The pros can always do it cheaper than I can buy the kits for.

R7 per inch. I've been told anything after 7 inches is a waste of money. Another way is 2 to 3 inches of foam and then net and blow in the rest. mtmuley

I used the tiger foam kit for a wine cellar in my garage that measures 11'x7'x7'. It was miserable and messy, if I was doing a significantly bigger space I just have somebody else do it. They're going to be faster, more consistent and they have to deal with cleaning it up.
