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!

    I highly recommend these Portland-based insulators:

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