“Crinkled housewrap” or tar paper under exterior foam?
In the “Mind the Gap” article at http://www.buildingscience.com/documents/insights/bsi-038-mind-the-gap-eh — If I understand correctly, when covering a plywood or OSB sheathed wall with foam, Lstiburek recommends a “crinkled housewrap” between the foam and the sheathing for diffusion redistribution. Would tar paper/building felt work in this situation?
