I were contemplating a radiant barrier- sounded like a good suggestion- but If I am Listening to you appropriately the ideal financial commitment could well be further cellulose - A further 6 inches? more than the present insulation. I think that would do two matters: boost the R value, and decrease air infiltration from the fiberglass.
It really is easier to incorporate radiant barriers right into a new home, but You may as well install them in an present property, especially if it's got an open attic. In a fresh household, an installer typically drapes a rolled-foil radiant barrier foil-experience down between the roof rafters to minimize dust accumulation to the reflective faces (double-confronted radiant barriers can be found).
