"Good point Brad.  I wonder if there is something IN my attic that was not detected and is now encapsulated in the attic, in the cellulose?   HMMMMM..... A lot to think about.  Thank you again for being a sounding board in this thread.…"

"Jan, you bring up another possible source of that bad odor, the Icynene. If the mixture of Part A and Part B is not in the proper ratio, you will get chronic out-gassing of odors. I previously mentioned the possibility of Ammonium Sulphate in the…"
