Exposed air barrier in garage?

I pulled down some mouse infested fiberglass batts in my mother in laws 2×4 garage walls up in Maine this weekend. They were covered with ploy & no sheetrock. Think I’m going to replace them with roxul batts. She doesn’t want to pay for sheetrock, so I’m wondering what my options are for an air barrier. And do I really need one in an unheated space like this?
Thanks,
Steve
