Okay, now - please don't anyone get fussy with me for asking an ignorant question.
RE Xcal's pictures, insulating attic with rigid foam board on the bottom edge of roof rafters: When one does this, is insulation at/between the ceiling joists then not needed? Is the rigid insulation at the rafters all that's needed for the attic? [including, of course, what he's done on the gable ends, et al]
This type of discussion should probably have a thread of it's own but in the meantime I will quote what I posted to another member earlier in this thread.

You should research conditioned or unventilated attics. It has become more popular in recent years.
