Cellulose over Icynene??


I just added a 28x28 2-car garage to my 2-year old 1800 sf house. I am going to blow cellulose into the attic, and I am kicking around blowing some cellulose on top of my Icynene (R-30) in the attic of the house as well while I have the blower on site. (I can get the blower for free if I buy a few extra bags of cellulose.) I am in southern Illinois and they IECC guidelines recommend R-38 for my area.

1) Is this okay (i.e. safe, not going to cause a chemical reaction, etc.)?

2) Is this advisable? Is it worth the extra time and expense, as minimal as they may be, to add extra R-value with the blown-in cellulose? Will I compromise the open cell foam if I cover it with cellulose?

That should be fine.

Blow it to and R-50 and make sure they use a borate only cellulose.

Thanks!

Does anyone have specific experience covering open-cell foam with cellulose?

Yes.

What type of information were you looking for?

There is not reactivity issue and even less potential for it if you use the borate only stuff.
