I was inspired by Rob Myers’ house build and have my own house underway in Midcoast Maine. I have a 2×4 frame, sheathed with Advantek and wrapped with Blueskin. My plan is to attach 6″ EPS to the outside with battens and long screws into the frame, with vertical pine siding. Inside I plan to insulate with 3-1/2″ rock wool. My question is whether I can apply wood paneling and/or drywall directly to the inside surface with no need for further air or vapor sealing because the Blueskin takes care of that and the percentage of R-value outside to inside prevents condensation in the wall.
