    I would like to insulate between the floor joists in my crawl space.

    1. Crawl space is vented.
    2. Crawl space has a vapor barrier down.

    Joists are 16'in on center.

    Should I use faced or non faced and what about R value?

    I live in the Dayton, Ohio area.

    Any "facing" should face the conditioned area, so if your question was as a method of attachment, that's answered.

    R-19 batt insulation will fill the joist space and there are several products designed to facilitate retaining it in the joist bay.

    Another consideration is the distance between the floor framing and grade.

    Find a way to close all holes in the floor around pipes or what ever so you have no air coming from below and insulate any pipes below you floor level. The subfloor is considered a vapour barrier no paper or anything is wanted or needed.
