Thanks for the advice! We did talk to another contracter who lives and breathes "green" but he's not currently insured. Darnit! He mentioned some even newer insulating stuff made from either canola or castor bean oil? I hope I can talk the other guy into using soy, not just for us, but also for the workers who'll be up in the 120-degree attic spraying it.<BR>

I've been near it when sprayed and there is no noticeable odour. Even so, it's sprayed under the 4" concrete slab and on the outside of the block only. The ceiling is done with dense pack cellulose.<BR>

Some of the stuff is indeed toxic....I had a long talk with my guy here before I let him spray.?<BR>
