Chances of this wall assembly having any issues?
I’ve been working full time on a new construction build as the sider/misc. framer/fix subs less than quality work. The owner builder is a friend and works as a PM in commercial construction (I work for this company as a carpenter in the field) so he knows how he wants stuff done but also is pretty “old school” in his thinking of how stuff should work. The last house he built was 20 years ago. The house is in climate zone 5. New England.
His wall assembly is hardie siding>zip sheathing>blown in fiberglass>poly vapor barrier (not taped/sealed at any seams or outlet boxes, just stapled on and cut around penetrations)>gypsum board
His other wall assembly is brick veneer>1 inch ventilation gap>Zip sheathing>Blown in fiberglass>poly (installed the same way)>gypsum board.
I know I have read from martin’s posts that poly shouldn’t be used in climates running AC more than 1 month a year and I also advised him that poly on the brick veneer walls isn’t recommended for our climate zone. But I also have read that even when wall systems aren’t ideally constructed most houses won’t have moisture issues.
He said his last house had poly with vinyl siding and was just fine the whole time he lived there and poly is just how people do it here.
I’m young and learning this all as I go and trying to take in as much information as possible through this experience for when I build. So back to my title question, what are the odds that these wall assemblies in our climate zone will have any issue?
