Constructing a double wall assembly in southern Maine. Any advice on a competent dense packed cellulose installer? Any opinions on open cell vs cellulose in this southern tier of zone6? Thanks for any input!

In my opinion, there aren't many situations where open cell foam can out-perform cellulose.
