   Probably not cheaper than hiring a pro to do it, plus
   you are subjecting yourself to the intense toxicity of
   uncured foam.

   This is what we have - http://www.ncfi.com/residential.html 

   Amazing stuff.

   Temperature dipped into the low 40's the other night.  Inside stayed in the high 60's ... with NO heat on.   For 10 hours.

   A couple of thoughts when you compare foam to other forms of insulation.
   On the positive side:
   1) most closed cell foams strengthen the structure substantially
   2) most sprayed in foams do a great job of cutting air infiltration On the negative side
   1) price-- compared to blown in cellulose blanket, the best bids I have seen are about four times the price-- or more.
   2)fire-- most of these foams are ridiculously flammable and must be covered with sheetrock or some other fire/flame retardant
   3) diminishing returns-- most of these foams do a great job when you apply 2 inches, but have seriously diminishing returns after that. That is why foam is often coupled with blown in cellulose, blown fiberglass or standard FG batts.
   4) Pollution and indoor air quality-- some of this stuff is better and some of it off-gasses really awful chemicals that will affect the overall environment and your indoor air quality.I am building a house for myself and have looked at all of this pretty hard. There are good reasons why a lot of the more experienced builders on this site (and some of the greenest of the green builders) like cellulose. Check it out.

   The NCFI insulation does not support combustion - in other words if you take a piece and hold a lighter to it the foam self-extinguishes.

   Thanks for all the info and input.

   I guess the perfect spray foam insulation would be non toxic, non flammable and as inexpensive as conventional insulation, cellulose etc.

    

   Thanks all

   I have looked at this and I have read up on it online. It looks like a great option, but I don't know anyone who has actually used it. Have you? It is written up as efficient, environmentally friendly, fireproof and very stable. I have seen nothing on the costs.Do you have any experience with this product?

   R-3.9 / inch (airkrete) doesn't cut it.

   First see if there are installers in your area.

   http://www.icynene.com/LocateDealer.aspx?country=1
   http://www.biobased.net/dealers/find.php
   http://www.insulstar.com/installers.html
   http://www.corbond.com/find_installer.htm

   If you have no luck with that then go the DIY route.
