How to handle vapor barrier around floor joists between upper/lower floor

[byggarebobuppland]

Wondering how one normally deals with the vapor barrier around the joist between the upper/lower floor according to the picture?

Is it enough that I pull down the vapor barrier from the upper floor around the joist and tape with age-resistant tape next to all 215x45 boards, or how do I proceed? As seen in the picture, I have so far plasticized the lower floor.

In your case, it already looks like the joist is in place, and then it's difficult to do anything about that fact. I also have no tips on what to do in this situation. But for those who are building and have not yet installed the joist, I can suggest the solution I used in my own construction. I simply pulled the plastic behind the horizontal beam, and then the floor joists are attached to the beam with joist hangers. In this way, you get completely sealed plastic without needing to fuss for a single minute with taping/sealing around each floor joist.

The image is not entirely optimal for describing the construction, but I believe it can contribute to a better understanding:

Drop the plastic between the beams, tape against the plastic and the beams. With the right tape, it adheres well to wood.

Or seal with plyfare strips on the sides and tape on the short sides (on the 220 x 45 beams)
