Framing what? Are you going to finish the attic? If so, you want to insulate the ceiling, not the floor unless a portion of it will be against an uninsulated space.
What is insulated now?

I am giong to start faming the attic into 2 bed rooms. Right now there is no insulation in the attic besides the sub floor. The insulation in the sub floor is prob from when the house was built, in the 50's. Ive been lookin into weather the sub floor needs to be insulated now that im going to finish it off. Ive heard yes, its better for energy efficiency. Ive heard no, " they only did that cuz they did not finish the attic when it was built". If there should be insulation there, then im going to need to replace all of it.

The basic idea is that you want to place insulation between heated/cooled living space and unheated/cooled empty attic space . The paper or foil side goes toward the conditioned space . Some insulation is also rated to insulate sound , you might want to place some in the floor for that purpose .
