I live in Virginia and I have a minimum of one inch of foam board plus spray foam in my old 2×4 walls and am about to install the fiberglass insulation. I bought R-13 insulation with Kraft paper. Should I take the kraft paper off when installing the insulation?

Duane,
You can leave it on or take it off -- either way will work fine.
