How likely is it that 54" sheetrock isn't available in a well-populated part of the continental US? I got a "talking" from a builder who didn't like my specifying 9' walls be/c of the 1' "waste" on the rock. I said I was thinking of 54" rock, and he said it's not available there. In my mind, I was thinking, "liar, liar, pants on fire," but I didn't say it. So, is 54" that hit-or-miss around the country? Or is he likely being lazy and just wants to stick with 48 from habit? Or something else? I could call the suppliers in his area, but I don't really like doing the "I told ya so" thing.
While we're at it, he said he can only get 10' metal studs. Every supplier web site I've seen lists other lengths, too, and says anything else is available. Is getting 9' studs that difficult? And does the price outweigh having to pay for 10' and then cut them each down?
