Vapor barrier - paper?

[Distordera]

Need some advice.
I'm tearing down wall coverings in an old house to route electrical and more.
It seems to be regular paper used as wind barrier/vapor brake.

Would it work to staple up regular paper (like packing paper or floor paper) to restore the wall?

It doesn't cost an arm and a leg to buy a proper ångbroms, does it? Then you know it's done properly.

Is it gray tar paper or is it black tar paper more like windproof paper?

I know that some house manufacturers used tar paper around bathrooms, but then the mat was the vapor barrier, so the tar paper was really just to hold the insulation in place. What we today call windproof paper ac350 was used for a while as a "vapor barrier" before plastic took over, and it is denser than paper but not exactly plastic either.

It doesn't cost a fortune to buy real vapor barrier, does it? Then you know it's done properly.

It sounds like you're suggesting that builders in the past weren't aware? The houses I've helped demolish have all had paper as an air seal (or vapor barrier as it seems to be called today).
Of course, I can afford it, there's a difference between "rag" for a few ten kronor and an eco air seal for 1600 per roll plus shipping.
Eco vapor barriers seem to be mostly expensive because they can be and to meet building standards for tear strength, etc.
Note! I don’t have facts here. Anyone with experience?

Is it gray papp (paper) or is it black papp more like wind barrier?

I know that some house manufacturers used papp around bathrooms, but in those cases, the flooring was the vapor barrier, so the papp was really just to hold the insulation in place. What we today call wind barrier ac350 was used for a time as a "vapor barrier" before plastic took over, and it's denser than paper but not exactly plastic either.

It's brown thicker papp. Air barrier I believe it was called in the past. That is, not the tar-smelling wind barrier that is often found behind exterior paneling.
