[Greenbuilding] Foam insulation advice needed

[Bobbi Chukran]

Thanks, Mike!  My main concern is that it not out-gas for a long  
period of time.  Interesting that you combined it with the fiberglass  
batts.

We had also thought about doing some kind of batts in the attic floor  
and cellulose in the walls as we can, later on.

We haven't actually seen the price for this yet, though, so it might  
be prohibitive.  In which case, we're back to the same ol'  
stuff...cellulose or fiberglass batts.
