Smart or not? Combining closed-cell and open-cell foam
I had a recent conversation with a BPI certified energy auditor. We were talking about encapsulation solutions for my 1950's attic spaces. He suggested the use of 1 inch of closed cell foam on the roof deck followed by 8 to 10 inches of open cell fully encapsulating the rafters. Is this a good or bad idea?
