As far as I know Roxul is basically the same as fluffy fiberglass, so use whichever is less expensive.

I don't know what ram board is. I've used thick paper and card stock with good results.

Ram board is a fiber product that you would typically see on a construction job site and is used to protect wood floors while construction is still taking place. Here is a link to it.
