Waiting for a ballpark quote. It looks like $0.65 to $0.85 per bdft of
foam. So about $1,000 per inch of foam on just the walls.

Not sure this is economical. I inquired with the SIP plant to see if
they know of a contractor in my area. Since SIPS with shipping and 6"
of foam between two 3/8 CDX panels at 10' x 4' wide are less tahn
$6,000 shipped. This price on spray foam seems REALLY high..
