Radiant roof sheathing being installed at another Hibbs Homes custom home near St. Louis Missouri. Radiant roof sheathing is plywood or OSB (Oriented Strand Board) with a thin layer of aluminum on one side to help reflect the suns radiant rays. Your attic stays cooler, your home stays cooler and that leads to a more comfortable living environment and lower utility bills. The product is Energy Star rated and according to its website, “can lower roof surface temperature by up to 100-degrees” and “can reduce peak cooling demand by 10-15 percent.”
Radiant roof sheathing used to cost more than standard plywood/OSB, but lumber prices are down and product competition is up, making radiant roof sheathing an affordable option. A similar type radiant barrier can be added to existing roof sheathing during renovation projects.
