New Home – Wall Assembly Review
I’m building my first custom home this summer and could use GBA’s collective wisdom to vet the wall assemblies.
Logix Platinum ICF basement (R-28)
2×6 advanced framing, blown cellulose, 7/16″ OSB, Tamlyn Drainable WRB, 1.5″ Terrafoan EPS, Fiber cement or steel siding.
Conditioned attic with min. R-38 closed cell spray foam
“Innie” window placement
Will placing the drainable WRB between the sheeting and EPS cause air flow that will serve to defeat the EPS insulation?
Does this mean I should move to an “Outie” window placement?
Should I be concerned with air penetration through all the siding fasteners that go through the EPS and WPB? How can I mitigate this?
Other comments concerns?
Thanks in advance for your help to this newbie!
