As I wrote during the article, the influence of the radiant barrier on a improperly insulated wall is more significant than on the properly insulated wall.
I'm trying to improved insulate the attic of the 1200 sq foot ranch in upstate Ny. It's 8 inch fiberglass batts unfaced.

By way of example, take into consideration only one Tale commercial creating with steel studs, foil faced polyiso sheathing, two" inch airspace (ventilated), and dim brick. With this layout the brick would take in and emit important amounts of radiant Power and by my Examination, stops considerable amounts of heat from moving into the making as it has the compulsory air Area for brick weeping that is also expected for your foil to work the right way.
My house is located in southern North Carolina which usually has 5-6 months where the A/C is operating nearly all of the working day/night and four-five months exactly where the warmth (Gasoline) is managing.
