2×8 rafter cathedral ceiling insulation
Looking for info on improving insulation for a cathedral ceiling in a zone 5b house built in the 70’s 2×8 rafters. Horrible ice dams in winter. Heat radiation in summer. Want to know how to insulate with out tearing down roof or drywall IF possible. I’m thinking spray foam is the best option for air sealing. i’m I correct? Thanks for any info.
