When radiant sun energy strikes a roof, it heat the shingles, felt paper and roof decking by conduction, it causes the underside of the decking and the roof framing to radiate heat downward through the attic toward the attic floor. When a radiant barrier is in place most of the heat radiated from the hot roof is reflected back toward the roof and this reduces the amount of heat that moves into the rooms below.
