Cellulose vs. Fiberglass Insulation
I have a 100-year-old cedar shingle-sided house with plaster interior walls. I am considering having dense pack insulation blown in from the exterior. I’m weighing between cellulose and fiberglass but also weighing the moisture reliability of the shingles and 15 lbs. felt underlayment to keep the insulation from getting wet (and will the wood plugs stay watertight for a few years until I re-shingle the house). I have no known issues of moisture intrusion. Thoughts on which insulation to use and on the potential for moisture to be an issue. Thanks!
