[Greenbuilding] Foam insulation advice needed

[Bobbi Chukran]

We finally got some info. from the insulation guy for our new/old home.

He proposes using an open cell foam, Demilec Selection 500 in the  
attic rafters.  I'm concerned because even though the company has  
LEED ratings, etc. that product is still polyurethane based.

I mentioned that I wanted water-sprayed, and indeed that product is,  
but I'm still leery of the health issues.  Since I'm chemically  
sensitive and have asthma, and since we'll be working in the house  
(although I won't be in the attic) for months, then living in it, I  
have to be cautious.

All of the green building info. sites say it's a great product for  
insulating a home.  But what about the health of the inhabitants?   
That's what I have to worry about, foremost.

Any cautions, comments, etc. about this product?  Thanks!
