Moisture barrier to be or not to be
Now I'm going to bring up a question that comes up now and then, and everyone is equally divided.
But I just want a little final input.
My workshop. It won't be warm all year round. During the coldest winter days, it will probably only be around 0°C-. That is, it heats up when I'm there.
So the question is. Should I have plastic right before the drywall on the ceiling and walls, or maybe just paper? Or skip it altogether.
The walls are: wooden facade. 28*70, paper. 45*95, 45*45, and then the question is what should I have before the drywall. (I'm running cables on the surface, so I have nothing in between)
The ceiling is.
Rafters with 200+ insulation. then below 28*70. and then there. Paper or plastic?
As I said, no long explanations about how it works, but more. How would you do it considering that it won't be warm all year round...?
Thanks for the answers

I imagine it matters less in a workshop than in living space because you don't produce as much moisture. How often will you cook, hang laundry, or shower in the workshop? Will several people be sleeping there permanently? Some claim that you shouldn't have plastic in the walls if it's not heated constantly. The experts can explain why, but I don't think it's so critical how you do it.

But instead, you drive in soaking wet cars and with snow on 
I will probably go without plastic and place cardboard on top of the insulation so it doesn't gust straight in.
I'll report back in 10 years

I ran plastic behind the drywall in the garage since it's heated all year round, but only about 5-10 degrees.
Probably doesn't matter as you wrote. I had an excessive fear of moisture and installed a small fan that runs for half an hour a couple of times every day and replaces the air. Right or wrong?

I will run the dehumidifier as soon as I heat the slightest bit since I will have some bare metal items. So I will probably skip the plastic entirely.
