Abstract
A decking or sheathing material for roofing includes a sheet of plywood or OSB with a reflective layer of foil material adhered thereto, the foil material including a layer of metallic foil such as aluminum and a kraft paper backing. The roof decking is fastened to rafters in a typical roof structure with the foil facing downwardly and exposed to air. A machine for applying the foil material to sheets of plywood includes a conveyer belt table for conveying the plywood sheets in succession, an adhesive roller for uniformly applying a layer of adhesive to the upwardly facing surfaces of the plywood sheets and a roller for pressing the foil material onto the adhesive-coated surfaces of the plywood from a supply roll.
