Correct drywall screws

[Ionkontrol]

Hi,

I am about to put up a new ceiling at the weekend and would like to know the best screws to use.

I am putting res bars straight up on the wooden joists.

Then a layer of 15mm soundboard, then another layer of 15mm soundboard.

So, what size/type screws do I use putting up the res bars,

Also what screws and length should I be using for each layer of PB?

Thanks in advance.

I would go
32mm dry wall screws for resi bar to timber joist.
ditto for PB to res bar
then 42's or 45's for the next layer.
