Certainteed Membrain discontinued. Alternatives?
After doing a few minutes of searching, it appears that Membrain manufacturing has been discontinued due to covid. I’ve begun insulating for a whole-house renovation (one of those never-ending, DIY, room by room jobs). I’m using mineral wool/rock wool/ whatever you want to call it, which doesn’t technically require a vapor retarder as I understand it, but some people seem to prefer to include one. Seemed like a reasonable expense to me, so I had decided to follow suit and have already insulated a couple rooms in this way.
I’ve been relatively lucky dealing with covid-related construction complications, where I’ve been able to move onto other projects within the remodel, but finishing the insulation in the bathroom I’m currently working on is the top priority. Should I carry on putting up drywall and not worry about not having a vapor retarder?
I’m in climate zone 5, by the way.
