Green Building Q&A: Insulated siding question

Let me ask you: Do you think that siding, which will let air all around it, is going to offer an appreciable amount of insulation? Consider plywood instead of OSB. Do a little searching here and you'll get your answer on the foam against the roof sheathing. (I think "not".) I did not see a vapor barrier in your list. Is that intentional? Search here for the story of the business that went belly up in S Ohio because they used vb's, and then the home owners ran air conditioning. (The problem may have been more to do w/ the brick (?) on the outside than the vb, but I doubt that you need a vb in S Ohio. Just air seal well.) PS: I am not a pro. My bother in law has been sheet rocking in N Ohio for 30 yrs, and never has seen a vb used on a house.
