Trying to build a new house, but having trouble getting materials. Local lumber yards do not have enough OSB to cover the outside of the house, but I did find one that had enough ½ inch, 5 layer, plywood. The house will then be wrapped in Tyvek (58 perm) or Typar (12 perm) not sure which one to use and then bricked. Will the climate in Kentucky be too humid for the 12 perm wrap? Any pros or cons on the ply wood, OSB or the house wraps?
