Cathedral ceiling insulation method advice
I have a 1970s house with cathedral ceiling in the living room. We tried to get the house insulated up to code and need some advice. One insulation contractor came back with suggesting spraying 2" closed cell form in the cavity and add 8" fiberglass batt to make it R39. He called it a hybrid method. Does this work? Will moisture trap between fiberglass batt and the closed cell form creating condensation?
