We have a new post-and-beam home. We’ve put in 3″ of ccSPF in the walls and are thinking at adding R-13 kraft-faced batts over this in the loft. Because of the way the exterior walks are framed, there is 2″ of spray foam between the interior studs and the exterior sheathing, except at the posts and beams. Is there going to be a potential moisture problem with using the faced batts?
