Interior wall - attaching top plate to sparse paneling

[svanstrom]

I am going to build an interior wall against a panel ceiling where the panel is nailed to furring strips. The interior wall will go in the same direction as the ceiling joists and therefore crosswise against the furring strips.

The risk is high that the wall will not land exactly under a ceiling joist, and my question is: do you think it is sufficient to attach the top plate solely to the furring strips, or should I somehow open up more of the ceiling and add additional framing?

If it's enough to attach to the furring strips, should I remove ceiling panel boards where the wall will go, or can I attach through the ceiling panel and into the furring strips?

It is enough to attach in the glesen.
If you want good sound insulation, remove the ceiling panel.

It is enough to attach to the studding.
If you want good sound insulation, remove the ceiling panel.

It also depends on how you view the future. If you plan to remove the wall in the foreseeable future and want to keep the panel, then let it remain. Otherwise, cut it now so you won't have to when you eventually replace the ceiling panel...

It will likely make it easier if you want to run electricity in the wall as well.

Projects like these, of course, tend to end with replacing the ceiling panel and renovating the entire floor

Thanks for the responses!

Then I'll remove the ceiling panel, soundproofing is of utmost importance because it's going to be a bedroom at the cottage for my kids who are currently sharing a room, and the older sister is starting to get tired of the little brother's noise

Hehe, yes, I will probably replace the ceiling panel in the new room in the future, but it will have to wait a bit. The advantage of it being a holiday home is that it's not the end of the world if it's not perfect everywhere
