Insulation Question

Inside the weatherproofing is the criteria for this credit.

I suggest you look at the illustrations in this credit in the v4 Reference Guide, which show different roof construction types and where the "line" is, as it's different depending on type of roof, roof deck, etc.

Page 673 of the reference guide shows two flat roof examples of where the plane dividing interior and exterior lie.  Both examples are from flat roof applications, and both examples consider the vapor retarder to be the layer dividing interior and exterior for the purposes of the credit.  In at least one case, the vapor retarder is between two layers of insulation, which would then put some roof insulation within the scope of the credit, and other insulation outside the scope of the credit. 

We have in our case a building that has a sloped roof application, blowing in around R-60 worth of cellulose insulation.  That insulation will be on the exterior of the vapor retarder and the air barrier, enclosed within an unconditioned attic. While the reference guide doesn't contain a sloped-roof example, if I extrapolate from the two flat roof examples, the blown-in cellulose in my example would not be within the scope of this credit.  

Anyone disagree?
