In connection with the upcoming tiling in the bathroom, I had to put up extra studs. A piece of the black paper that was on the outer wall got damaged during the demolition - and unfortunately, a piece even seems to be missing. I don't want to buy a whole roll to replace about one square meter of paper. Replacing it with something like roofing felt would be too thick. I do have a roll of paper that I think might be the right kind, but it's probably only about 20 cm wide and has a thin plastic film on one side. So, too narrow.
I'm looking for suggestions on what I should replace the missing piece with? Or is it necessary to buy a whole roll?
Probably a very simple question for those of you who are builders and know what that thin black paper on the inside of the outer wall is for.

Thank you Carla, it's probably as you say and then I should be able to replace what's missing with, for example, that brown paper you lay on the floor during painting work. Moreover, my partner found most of the paper I was missing. It was still on one of the construction boards... ;-)
How stingy can you get? It all concerns your house and mine during a bathroom renovation. A roll of wind barrier costs 250kr. Compare that to the potential costs if future buyers of the house consider it a hidden defect...
Is it really considered a hidden defect if I replace a strip of black windproof paper measuring 1.1 + 0.25 m², so a total of 0.25 m²? As a layman thinking about wind protection, I thought paper is paper, and besides, I can fold that strip of paper I intended to use 2-, 3-, or 4-fold. But when you write like that, I realize I was on thin ice and should buy a roll. I intend to do so. Good to know I was so completely wrong. Thank you Suhagg and Hubbe2 for the information!

Where in the wall is the paper located, inside or outside the wall? I suspect inside since the torn-off piece was attached to a construction board and is therefore a diffusion-tight paper, common before the "plastic age". You can replace it with plastic. Windproof paper is used on the outside of the wall.
However, since you are going to tile, you should also waterproof the wall with an approved method, and under such waterproofing, there should not be any vapor barrier in the wall as you would then have double vapor barriers. If that's the case, the torn-off piece of paper does no harm, quite the opposite.
