Hello all knowledgeable people!
I have a few questions regarding the age-resistant plastic.
I am in full swing with an extension.
Between the sill and the floor, I have laid sill insulation but no plastic. The sill insulation is flush with the stud. How do I get it tight when I continue with the plastic from the wall down to the floor? Theoretically, moisture could want to travel that way, or am I thinking wrong?
How do you do it in the laundry room with the plastic? I'm going to have a waterproof layer on the floor that will be self-leveled.
Should I let the plastic go out onto the floor a bit (5cm)? before I level? Or how is it done?
And then there's a bathroom on the upper floor. Apparently, you shouldn't have plastic outside the waterproofing layer, should I just end the plastic where the bathroom interior walls come, or should I fold it around the studs before I close it up?
In the sloped ceiling, I will have paneling, I assume the plastic should remain there?
It might have been a bit messy, but I hope you understand.
Best regards/ Anders

Normally, bathrooms are probably also sealed with plastic, as there is a risk of puncturing the waterproofing layer in the bathroom, allowing moisture to seep in, which then never dries with double waterproofing. However, in many constructions, this risk seems to be overlooked.
Hello again.
No one has sensible answers to the first two questions?
Then another thought came up. I have a 170mm frame with plastic on it, then a 45 on this. To make it work with the drainage on one wall, I should place a 120 stud instead of the 45. Can I put the plastic inside my 170 stud in this case as well? It's said that the plastic should be placed as far in as possible, what do you think?

The plastic should be placed a maximum of 1/3 into the wall, so if you're using a 45mm installation space, an absolute minimum of 90mm is required outside the plastic.
Or in your case with a 170 frame (assuming there will be 170 insulation outside the plastic), you can have a maximum of 85mm installation space. What you can do is use a 120 frame but only insulate a maximum of 85mm and leave the rest empty, then you are within the 1/3 limit.

I understand it as folding out the plastic a bit so that the floor construction stands on it, I am not certain about this, so I am curious about it too.
Hello again!
Reviving this thread. I have now put up OSB and drywall in the upcoming laundry room. The plastic on the outer wall is folded out on the floor, as well as the plastic under the inner wall that extends a bit onto the floor. What do I do with this now?
The floor will be leveled with self-leveling compound. Do I fold the plastic up onto the drywall before leveling or do I cut the plastic where it is now?
In theory, the compound could lead moisture up into the wall, or am I wrong?

normally there is low moisture in the slab and leveling compound.
and all incoming water shall run on the waterproofing layer
