Re: Does Rigid Foam Insulation Trap Moisture in the Walls?

sprayed in Closed cell foam or the 1.8 density is only a vapor diffusor until it is 4 inches deep, then it is a vapor barrior. If this home has closed cell foam in it that deep the external wall strength is about 500 % stronger than regular construction.
The ISO side of the foam is glue, like gorilla glue. As long as the contractor knows how to properly control moisture in the building, all is well.
