I am building a new home in WI and put 1" tongue and grove pink foamboard with taped seams on the outside of the sheathing, I am using LP smartside siding, the walls are 2x6 and I have R19 unfaced insulation in walls, planning on 6mil poly vapor barrier. My questions are
1. Is this correct for a vapor barrier system?
2. I am planning on insulating and poly vapor barriering both side of my interior walls - anything wrong with this procedure?
Realistically if moisture can't get in with the vapor barrier on both sides of the walls, interior and exterior, there shouldn't be any moisture/mold issues, am I right or wrong in this philosophy?
