Hello Collarandhames,

I don't believe I can agree with many of the perspectives you just shared about vapor barriers, yet understand that view is common. I would love for you to join Permies.com and perhaps read some of the information there and engage in a the same conversation there about these concepts of "airtight" architecture. Not to dissuade you at this time, but I think you would enjoy reading some of the other perspectives in natural/traditional building modalities.

Hope to see you there,

j
