Plastic sheeting as drywall Vapor Barrier?

I’m wondering if plastic sheeting is a good replacement for fiberglass batt paper backing that has been damaged. During renovations, i had to remove the fiberglass batt insulation from walls. I reinstalled the same batts, but the paper was damaged or removed on some pieces. I was planning on covering the whole wall in plastic sheeting before installing drywall, to replace the vapor barrier that was compromised. Is there any reason I shouldn’t do this? I live in MD. I have seen conflicting advice online. submitted by /u/Proto_Sapiens [link] [comments]
