I'm a bit confused by that statement.
A radiant barrier should be on the underside of the roof decking. Either painted on or a foil that is already glued to the roof decking, I have the latter.
I have seen the rolls of radiant barrier that you staple to the trusses or lay on top of the insulation in the attic.
But either way I have always read that you do not want to have insulation over the radiant barrier.
