Hi – I'm a homeowner who has spent a ton of time reading a few dozen threads here (invaluable), other posts/articles elsewhere and have arrived at a crossroads…open to advice and/or questions I should be thinking about to help me arrive at a decision. I can provide as many details as needed on my energy audit, house location/construction/details, monthly energy expenses, etc. if necessary.
It boils down to this (Note: no need to use attic for storage/living space)-
1. Use blown-in cellulose in attic, lots of air sealing, CC foam in cantilevers/rim joist
