A google search for spray foam insulation will turn up a list of companies
selling the stuff, there are some options for slow rise (for filling walls),
fire retardant, and I saw one anti-microbial. For the standard stuff prices
seem to be $565-600 for a kit to do 600 board feet (600 square feet one inch
thick, about R6). I checked on this a few years ago when I was thinking of
doing the "ceiling" of my crawlspace and the prices were exactly the same
but the crash put those kinds of spending plans on hold, sigh, so I can't
recommend a particular vendor. FWIW, www.tigerfoam.com seems to have decent
instructions :-).


This sobered me up. I don't think I want to chance a bad foam job.
Dead fish smell, eh? Lovely! http://goo.gl/IDB9x
Amine sensitivity isn't harmful? (from other links)

Pass!

Have an experienced contractor do the job - the DIY kit is NOT the
same. The good stuff is sprayed and I believe there is heat involved -
not sure if it is an exothermic reaction only, or if the stuff is
heated as part of the application process. My Dad's last two houses
both had spray foam - both done by the same local contractor. There
are two big well-known contactors in the area that likely do 80% or
more of the spray foam insulation in the area.
