Barrel vault insulation
I live at the border between zone 4a and zone 5a in Kansas City. My home has a barrel vault (see photos) with sheetrock following the curve on the inside, 6 in rafters withR-19 fiberglass bats, unvented, and then the decking and roof.
We are planning to replace the roof, likely with standing-seam metal. Is there any insulation that we could put on the deck under the metal, or any other ideas to improve efficiency when we replace the roof?
Thanks for your suggestions.
