"GBR - thanks for the links. Off topic - there's an interesting bit of info in the CUREE paper about orientation of drywall vs wall strength e.g. wall is 50% stronger when drywall is applied horizontally. I'm sure I've seen that topic debated a few times, if I recall."------------------------- I usually show this, first table; https://docs.google.com/viewer?a=v&q...U1o3kfoOlKl-7Q
And this, pp.12, and fig.9; "Results of tests for 24-foot walls, with and without
windbracing (fig. 9), showed a 50 percent increase in
ultimate strength for horizontal versus vertical panel
orientation. For the vertically oriented panels, nail loads
along the bottom edge caused the gypsum core to crack
and fall away from the panel." From; http://www.fpl.fs.fed.us/documnts/fplrp/fplrp439.pdf
