[Greenbuilding] Slab on Grade Insulation

[Bobbi Chukran]

Lynelle,

Do you know what your closed cell insulation is made of?  We're  
getting a bid from a guy to foam the ceiling of the attic in our new/ 
old home, and he couldn't even tell me what is used in the stuff.  I  
was under the impression that some of it is very toxic with  
outgassing/formaldehyde, etc. and I'd like to avoid that type.

Thanks!
