Rigid foam on the inside of basement walls
Per the details on the site, it shows rigid foam on the inside of the basement wall and then batts between the studs. Is there a moisture benefit of doing this? What is the real benefit of this vs batts? We do a handful of finished basements here in my area and everybody just does batts. Inspectors also require a vapor barrier inside but that is creating mold inside the wall and behind the barrier as we have seen that on jobs only a few months old that were insulated during the initial construction. I’m in northern Utah by park city so cold climate for sure.
