Greetings from Minnesota:
My wife and I are in the process of remodeling an alder home. Basically we have gutted the interior. My question is: We are planning to insulate the walls (2×4) with R13 fiberglass bats and then place 3/4 inch foil face foam over that. Do we need to install a separate vapor barrier or will the foam be sufficient? Of course we would tape the seams. We were also considering using the ploy wrapped fiberglass bats. Thanks in advance.
