Hello, I am planning on sheetrocking the basement in my house. I have a walk out basement so one wall is facing the outside. And there are two walls that I will be sheetrocking that are below grade level. I am wondering what types of insulation are best and how to insulate.

When i took down the old paneling there was the fiberglass R something behind it. Is the fiberglass rolls good enough or do I need to put the vapor barrier up too.

Thanks in advance.

No v.b. or vapor retarder required, or suggested; http://publicecodes.citation.com/icod/irc/2009/icod_irc_2009_6_sec001_par003.htm

Ok, just to clarify this. Since I live in North Dakota I don't need a vapor barrier? I can just use the fiberglass rolls of insulation against the concrete basement wall? I'll check what rating I need. But so it'll be concrete foundation wall, then insulation, then sheetrock?

thank you

No v.b. on basement concrete walls if under the 2009 IRC, check locally to be sure. I suggest foam board rather than f.g. on concrete; http://www.swinter.com/services/documents/ChallengesofBasementInsulation.pdf
