So, will the R-value Zip sheathing get you there? I personally prefer the R-9, but they make an R-6 also.How is everyone dealing with the requirements for insulation when it comes to the R value of 20 + 5ci in the stud cavity. Adding that 5ci is putting a big cost on construction. If you use rock wool at 5.5" it is just R-23

Ya know, I wonder why Joe didn’t think of that?It's a code requirement. People around here deal with it by doing it.
