I have gutted my bathroom and am installing R-13 kraft faced insulation between the exterior wall 2x4s.
Question… do I need to staple a vapor barrier (4- or 6-mil polyethylene) over the insulation or not? I have heard conflicting answers online and looked for this question here on this forum but didn’t find a discussion.
I know in certain areas of the country this is more important than in others. I live in Philadelphia, PA and my home is 45 years old.
Any help would be appreciated…
Thanks,
