Porch / deck over conditioned space — insulation question
Ok and thanks in advance. I have a small deck/porch located directly over a bedroom on the first floor. The area is approx. 5'x12' and it was uninsulated since the very early 1900's when the addition was added. Here's a little diagram. I'm wondering:
How do I insulate this area? I plan on replacing the worn out copper roof with a rubber membrane roof. The ceiling joists in this section are only 2x6 so I'm sure I would have to add some depth to accommodate anything close to code. Can it be done without venting? Putting insualtion on the top of the deck is not going to work so I'm wondering If just air sealing the whole area and pounding it with rock wool to R-50 will work?
Thanks...I'm in climate zone 6
