Abstract
A facing for wall board such as sheet rock, adapted to reinforce the board as well as to enhance its thermal barrier and acoustic characteristics. The facing is a laminate sheeting formed by a paper ply cold-laminated to a synthetic plastic oriented film ply, the opposing surfaces of the film ply being corona-discharge treated to render them receptive to adhesives. The exposed surface of the film ply is coated with a water moistenable adhesive, so that when this coating is moistened, the facing may then be adhered to the wall board to reinforce the board and to impart sound absorbing and decorative properties thereto. The film ply or the paperply in the facing is metalized to reflect infrared rays and thereby reduce the transfer of thermal energy through the board.
