I have a 3 story, Type VB, R-2 w/ sprinklers.
Can we apply EPS insulation over the sheathing on the exterior wall?
Per 602.5 Type V, 'any material permitted by this code'.
But per Chapter 26, it appears we need a thermal barrier if we do use EPS foam.
I ask, because i'm also getting conflicting information on the internet as well, that foam is allowed on Type V, without a thermal barrier.
