Another “help me design a wall” thread
I’ve read wall build articles here but I’m still ambiguous as to the placement of barriers. I’ve also watched Dana’s series titled, “Extreme 10 foot or less snowy knoll patch skiing”, but couldn’t find any relevant information there.
Zone 5. Inside to out: (sealed?) Drywall | 2X6 studs sealed with Ecoseal and filled with dense pack | either OSB or ZIP taped | 3″ poly foam taped | rain screen, vinyl siding.
From what I’ve learned here this wall will need to dry to the interior.
a few questions, if I may?
° Do I need any other thin barriers in this stack up anywhere such as Intelloplus behind the drywall or anything on the outside of the sheathing?
° Since I’m using exterior foam and I intend to Ecoseal in the stud bays and plates, will I benefit from installing drywall airtight using sealants?
° Would I benefit from airfoil electrical gang boxes or is that a waste at this point? I’m betting the answer to this will pivot on the above question’s response.
° Am I leaving anything out of this build, or adding unnecessary material?
