Obscure OSB air barrier questions
In general, is an air barrier composed of 7/16" OSB similarly effective as a 5/8" OSB air barrier, assuming all installation details were the same for both?
I have seen people using caulk and without caulk when fastening OSB to structural lumber, I assume that the concept with the caulk is that they're trying to seal the penetrations through the OSB?
Are the air leakage through holes created (and filled) a significant source of air leakage?
