Flash-and-fill double-stud walls?
After reading the Building science article regarding moisture monitoring in high R value walls:
I became interested in the idea of a flash and fill double stud wall. (new construction climate zone 6 - northern New England) as a "safe" wall for my location.
It seems that all of the literature on this approach includes using 2-3 inches of closed cell spray foam, depending on hdd, and then using dense pack cellulose for the remainder of the cavity. Would there be no benefit for the remaining portion of the cavity to be filled with open cell spray foam instead of the cellulose? Installation costs are similar in my area.
