Plywood vs. OSB vs. Gerogia Pacific gypsum roof decking.
I am researching what decking material I should use on a new home. Seems to be good and bad on plywood and OSB. I have read the GP Web site on their gypsum decking and it sounds very good, as one would expect. I plan to use a Slate look steel shingle with 50 year warranty over this decking. Any known pros and cons on this material any of you can share?
