Should you insulate the exterior of a house with rigid insulation if you have spray foam inside?
A customer of mine wants rigid foam on the outside of his house to stop thermal bridging, and then wants to have either open or closed-cell foam blown in the interior.
I was wondering if that would be a bad situation for the OSB trapped between the two. What would be good ok around?
