Abstract
A radiant barrier sheathing product formed by directly bonding an unbacked, metallized polyethylene (PET) sheet or film, or similar sheet or film, directly to a wood or cellulosic structural panel. A very thin layer of aluminum (or similar metal) is deposited via vapor deposition manufacturing processes onto one or more sides of a polyethylene sheet to form a metallized PET sheet. The elimination of the backing substrate eliminates the cost and conversion expense of producing a combined overlay product.
