I need help insulating my unvented cathedral ceiling
Here’s what I have: I am building a house in my existing pole barn. When I built it, I put my roof nailers on 2′ center, then put down fan-fold insulation, then placed my metal roof. I am going to leave my trusses exposed on the inside for a cathedral ceiling, and was wanting to put metal up for my ceiling between the trusses.
I am trying to figure out how I can insulate this. Can I use rigid foam board and put it all the way against the fan-fold and make it airtight, then put up my interior metal?
All the help on this would be much appreciated. I am stumped. Thank you.
