Using an "Arctic wall" design for a cathedral ceiling in Climate Zone 6
Wondering if the arctic wall design would be appropriate to use as a roof/cathedral ceiling here in CZ6 upstate NY. There is a comment about it on Martin's blog, but I didn't see any discussion : http://www.greenbuildingadvisor.com/blogs/dept/musings/how-build-insulat...
from inside out it would be:
2x4 service cavity,
1/2" CDX taped and sealed,
parallel chord trusses 12-12 pitch dense packed with cellulose,
vapor open WRB (suggestions for best product welcome),
I've done a lot of reading on the stackup being used as a wall in fairbanks, and there was some concern that it wouldn't fair too well in a wetter climate.
