faced vs unfaced vs encapsulated insulat

casharon | Posted in Energy, Heating & Insulation on

Where can I get good info on the issue of vapor barriers with insulation? I live in Northern California. With fiberglass batt insulation, I have always installed the vapor barrier towards the conditioned space ( walls, floor, and ceiling). But I have been advised to use unfaced batts in both floors and ceilings. Can I use encapsulated batts for the floors and ceilings?  Thanks for any input.

    This has been discussed quite a bit here--you could do a search for old discussions, but probably better would be to go to http://www.buildingscience.com. Sorry I don't know how to make a link to it.
