Here’s the dilema:
I am buliding my own home and have a 12″ concrete block foundation. On the interior I have covered the block with 2″ shiplapped Celefort 300 (foamboard). Interior to this I built a 2×4 stud wall for electrical, plumbing and added insulation as it has 3 12″ of pink batt insulation. I am under the impression that the foamboard would serve as a vapour barrier as well but my building inspector feels I should cover the stud wall with a 6 mil. poly vapour barrier before the drywall! Any suggestions?, Thank-you in advance for your replies.
P.S. The outside of the block has a coating of black tar, then 1″ foamboard and covered again by Delta house wrap. ( O.K., so I went overboard, It’s my last house!)
