Building in Zone 2 and am considering changing from my original plan to use spray foam.
Would like to use Roxul ComfortBatt in a 2×6 stud bay and Roxul Comfortboards outside of sheathing instead. Plan on using a self adhering WRB and the baseplate will be sitting on a EPDM gasket. Would like to gather some more detail on water and air sealing with this approach, specifically:
1. important areas of the framework and sheetrock to seal and the best sealant to use. This is a single story house sitting on a concrete slab with a single pitch roof.
2. transition between roof WRB and wall WRB at the overhang. I have seen some diagrams where the WRB was continuous between the two and some where the WRB stops at the soffit. It seems the continuous approach is best but how can that be done correctly when the overhang is 2 feet long.
