I am trying to improved insulate the attic of the 1200 sq foot ranch in upstate The big apple. It's got 8 inch fiberglass batts unfaced. I were thinking about a radiant barrier- sounded like a good suggestion- but when I'm Listening to you correctly the ideal expense will be additional cellulose - One more 6 inches? more than the prevailing insulation.
