Wind paper, plastic foil

[Lapiner]

We recently bought a house with a partially finished guest house about 50 square meters that had a frame with paneling, windows, brick, painting, etc. What's left to do is the interior work, which I have started on. I listened to some friends who are "carpenters" and they said you should have age-resistant plastic film on the inside. Now that I've put plastic film, battens, OSB, and drywall on the upper floor, I noticed there's a type of paper on the outside behind the paneling. It's white and seems to have some form of wax or similar. Could it be that it was supposed to be a moisture barrier and I've now put another one on the inside, or is it not an issue?

Worried about having to tear down all the drywall and OSB. :eek:

Grateful for help.

Behind the panel, there should be a wind barrier, so it is likely wind protection foil. On the inside, you install a moisture barrier just as you have done.

A completely different question, is it "standard" to use both gles and OSB? I was planning to choose.

Thank you for the answer. I have installed battens and plasterboard in the slanted ceiling. On the walls, I have installed OSB and plasterboard. I don't think one should have battens and OSB.

Okay, then we are in complete agreement; it was you writing both gles and osb that made me curious, but then it was in different places.
