Hi expert panel!
I know that the question about moisture barriers under wooden floors has been brought up here several times before, but I haven't seen anything where the wind blows freely under the house.
It's now time to fasten the thick floorboards that have been laid out to dry for a while, about 200x34 that will be laid directly on joists 45x220 cc60 (strips of rag paper in between). Thus, 220mm stone wool and fiber cement boards as the base. The question is whether I should have any moisture/vapor barrier directly under the floor. Personally, I like the idea that any moisture should be able to move freely in both directions (and it's easier to install without a barrier). As you can see in the picture, it's open under the house, so no moisture will be "trapped" beneath.
What do you think?
Thanks in advance!

I did like you, without a barrier, but I taped the fiber cement boards on the inside to avoid any drafts.
However, I had wood fiber insulation.

Thanks for the reply!
Yes, wood fiber buffers moisture, while stone wool is completely permeable. At first, I thought about taping, but I might go over with sealant from the outside if I experience drafts, because the most critical place is where the boards meet the planks that hold them up, and it would be a heck of a lot of taping from the inside if I have to do it around in each compartment.
