So I am fixing to put 7/16” OSB on my ceiling in my pole building. My trusses are 24” centers. The issue comes with the length of my building, it is 27’ long. I was looking at using the 4’x9’ OSB that way 3 sheets would cover the entire length. The only issue with that is the fact that the ends of the OSB wouldn’t hit a truss. I was thinking of putting the H clips used for roofing on the ends to help support it. The osb would never have any weight from above on it other than the R30 insulation batts which will also be held up by the tight fit between the trusses. Do you guys think that having the tail of the OSB ending in between the trusses rather than on a truss would be bad? Would it sag to much? If I buy 8’ sheets and cut it so it ends on a truss every time then I will have a lot of scrap. But obviously will do it if I have to. Thanks for any info.
