Timber frame cathedral ceiling
I know, I know, it’s another cathedral ceiling question… The specifics: I am building the house myself and the roof structure will be built like a timber frame house, but a shed roof. I am in Climate zone 3 (near the coast in the redwoods (California), and we get A LOT of rain in the winter 60-80 inches, sometimes more, so marine by Joe Lstiburek standards). I am trying to build a good home but not a passive house and will heat with a wood stove (free) and radiant heating, no AC required. This is a forever home, and because of that, and the fact that our climate is mild I am putting durability above energy efficiency when there is a conflict. I would like to avoid spray foam if possible. And lastly I am in the Wildland urban interface which has some vent restrictions but it is possible to buy special vents. These are the two options I have thought of and would like your thoughts on them, however, I could easily be convinced to scrap them and go with a different one. Just for fun the house I am replacing is a 900 sq. ft. cabin built in the 1950s… in the ceiling (R-11) walls (R-0) floor over crawl space (R-0). I know this would not do well in the east coast where most of you are, just a little insight into an old California home. I got the idea for the design with TOPROCK DD from the last Fine Homebuilding concept house but the videos and pictures were a little vague so it may be incomplete. If there is a more detailed drawing of their assembly as well that would be awesome. Thank you in advance.
