Zone 6 exterior wall construction
I have a question about proper wall construction here in Helena, MT. We get 11-12 inches per rain, and usually havd a period during the winter where outside temps don’t break 0° F for 3-4 weeks straight. There is no code enforcement where I will be building. 90% of new homes in our area are built outside if a code enforcement zone. That said, I want this house to last 100 years without any major redos. So my first question is exterior walls…Here is my plan from inside out
1. gypsum w/ latex paint
2. 5.5 of craft faced fiberglass
4. Draining Houswrap (obdyke hydro gap)
5. 1.5 in xps foam
6. 3/8 strapping for rain screen
7. hardie panel (board and batten).
Does this look like a good long term solution? Thanks for any comments and advice.
