I have a question that I can't find an answer to. I'm going to install a ceiling and have reconsidered a bit, the plan now is to install paneling that is 14mm thick and 120mm wide. Right now there is 11mm thick OSB behind this framed at cc30. The question now is whether it's possible to install the paneling in the same direction as the studs or if there's a risk that the OSB board will become wavy over time. It's not guaranteed that I'll hit the studs at some point. I don't think it should be a problem but I can't find any information on what OSB supports in this way. And no, it's not possible to install a grid as I, for various completely irrelevant reasons, can't lower the ceiling more. Does anyone have opinions or is it just a matter of going for it?

If you are going to put the panel on top of OSB, it should work excellently with "the same direction." 11 mm OSB likely has no problem supporting some paneling, especially if it is attached with cc30...
If you are going to take down the OSB, you would need to go "across" or space out though.

I have no plans to take down the OSB. And I don't think it will fall down either, but the main concern is whether there's a risk the board will sag. The ceiling will be illuminated, so if it does sag in a year or two, it will probably be very noticeable because of the lighting. I'm a bit inexperienced with OSB on ceilings, and if you try to search for it, you only find information on what it can support if it's mounted on a wall, but the tension is in the board's direction there, which is different on a ceiling.
