Response: The ceiling insulation type has been revised. The typo R-38 has been
corrected to R49 on the requested sheets. The note: for scissors trusses
I am not able to modify the table as it was adapted from IRS 2015. We include the table
to show typical insulation types. The number has been corrected only because we used
scissors trusses for this project.
