[Greenbuilding] Slab on Grade Insulation

[Lynelle Hamilton]

Hi Bobbi:

It's soy based closed cell, no formaldehyde.  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.

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