Another interesting thing I noticed about this (our neighbor's house is being assembled in this way, and a couple more in the neighborhood) is that they'll hold off on window openings until after the roof is put up. So these wall sections are framed for windows inside, then sheathed as if there is no window there. After the roof goes up and shingles go on, they'll cut out the opening and throw the windows in. It's pretty genius as far as waterproofing a construction site goes.
