Additional Attic Insulation - Foil

I have 2x6 ciling joists w/ new R19 insulation. I'm thinking of adding that foil type radiant barrier over the fiberglass foil side down for extra insulation, can't hurt right

Probably won't do much good and it could hurt - if it allows condensation to build up between it and the insulation then it does hurt.

Google "radiant barrier" and look for the site the DOE office in Oak Ridge has on them. It is the best site for info on radiant barriers and their payback (if it exists).
