Roofing – rigid insuation above, plus foam in roof framing bays
I am refering to and creating details based on this on your site https://www.greenbuildingadvisor.com/sites/default/files/Insulated%20cathedral%20ceiling.jpg
My question relates to the note that calls for breathable insulation on the interior. I want to use non-breathable closed cell foam in the bays so we do not have to vent the roof, which does not have an attic. Project is located in Pismo Beach, CA. Any way we can accomplish this?
