Our local building supply dealers tell us that an 11/32-inch thick, 4×8-ft. Ply-Bead panel will not sag if we use it on our porch ceiling (24-in. oc). My husband is skeptical, and we would appreciate some input from professional carpenters and/or builders. Thanks.

hang it so the strength axis is perpendicular to your ceiling joists. Why not change to 16" centers if you can. Shouldnt sag anyway. Good luck.
*Or if you do want it oriented the other way install 1x3 firring 16" on center perpendicular to the ceiling joists. John
*JTango,Regardless of whether you choose 24" or 16", put blocking in every two feet perpendicular to the joists and make sure you break all your joints on a block.Bevel the butt joints. Clamp a straight edge to the sheet and set you skilsaw at a 45 degree bevel. Make sure your straight edge is straight -- often a wooden 4' level has a crown of a 32nd of an inch or so. Not much, but it makes for a frustrating experience of hanging plywood.Check it with a string.Above all, Have fun!Dan
*I installed some ply-bead and believe it is good quality veneer ply.But I think the extra precautions suggested above are good ones. A few extra nails never hurt! The T&G joints in particular must be carefully concealed. And you really don't want your work to project FAKE.
*Is 1x4 really enough, or would 2x4 be significantly better? I ask this question for my own purposes, not necessarily relating to the origional question.
*Real beaded ceiling board is awful nice.
*Yes. Of course, only 1 in 100 non-carps would ever notice. As if that matters....
*1x4's could be better. If they are firmly secured and dry there will be much less of a chance of them twisting.
