till you seen an architect spec this stuff.

Wants to use 2 inches of the closed cell foam in a 2x4 stud wall (cuz his client already purchased it), then strip off insulation from an R-13 batt down to an R-5 (1 1/2") so he keeps the 1 perm. Check the video. I asked for an ICC-ES report. What I got was a letter saying it complies with the 2009 IECC and ASTM E84 The RESCHECK passed by 58% amazingly enough.

Yep, the old flash and batt system. crazy, but meets the specs I hear.

Who proves the R-13 becomes R-5? How about using 2x6 and don't tear apart the R-13?

I like the link.

Figured it would be a short time before DIY'ers get their hands on the product.

Flashover more likely once mr. Homeowner DIYer sprays on 10 inches of this stuff in his attic or crawl space and walks out.

Ok I'm lost, What is the issue with 2" of spray foam and 1.5" of batt?
