I bit the bullet and realized I cannot DIY blown-in insulation in the
kneewalls and other hard to insulate areas in the house. (Frame 2
story in Chicago, IL.) I've gotten estimates from two companies so
far.

But, I got one guy who is adamant that he use blow-in fiberglass, that
cellulose is lousy, dusty, dirty, and susceptible to mold. I do some
websearching, and find that fiberglass, however, is susceptible to
"fluffing" by the installer... They can blow it in in a way that looks
like they've filled the space, but it's more air than it should be...

So now I'm conflicted, and torn as to how to decide. Any installer is
going to be an unknown entity for me, no matter what, so I have to go
on stuff like BBB, how long in business and apparent "certifications"
in the insulation business.

Opinions, please!


Considering that you're supposed to be very careful around fiberglass
insulation that comes in rolls (and yet, still releases some material as
it's handled), I'd be concerned about a product that's able to be blown in.
Is it done primarily through holes made from the outside of the house? If
some work is done inside, is the guy prepared (with the appropriate fancy
vacuum cleaner) to clean up any dusty residue?
