A radiant barrier system may reduce heat flow into a structure. A radiant barrier system may include at least one internal airspace positioned between at least two radiant barrier layers having a reflectivity rating of at least 90%, the at least two radiant barrier layers comprising a layer positioned on top of the at least one internal airspace that reduces radiant heat flow by emissivity and a layer positioned below the at least one internal airspace that reduces radiant heat flow by reflectivity. A radiant barrier system may be incorporated between roofing products such as flexible roofing underlayments, sheet goods (i.e., plastic, metal or fiberglass), and wood products (i.e., plywood or oriented strand board (OSB)) and combinations thereof A radiant barrier system also may be integrated into wall products. |
