So, I just got off the phone with the person who submitted a REScheck. I asked him where he came up with the continuous R-value of 3.4 for the walls and ceiling. His answer was that for the walls he added up the R-values of the 1/2" gypsum board, the 1/2" osb sheathing, the 1" air space and the brick. The ceiling was 1/2" drywall, air space, 1/2" plywood sheathing and shingles.
I told him to provide documentation for that. Honestly, I don't think he is even allowed to use these materials for the R-value in REScheck.
Is it possible?
