Abstract: The present invention relates to a heat reflective coated structural article comprising a heat reflective component and a coated structural article component which comprises a substrate having an ionic charge coated with a coating having essentially the same ionic charge. The coating of the coated structural article consists essentially of a filler material and a binder material wherein the binder material bonds the filler material together and to the substrate and wherein the coating does not bleed through the substrate. Nonlimiting examples of the heat reflective component include, elastomeric coatings, aluminum fiber coatings, acrylic and polyurethane coating systems, ceramic coatings insulating paints, metal pigment paints, metal pigment pastes and aluminum flakes. The heat reflective coated structural article of the present invention may be incorporated into commercial roofing products.

Abstract: The present invention relates to a roofing underlayment system comprising two layers of a coated structural article which comprises a substrate having an ionic charge coated with a coating having essentially the same ionic charge or one layer of such coated structural article in combination with one layer of felt material. The coating of the coated structural article consists essentially of a filler material and a binder material wherein the binder material bonds the filler material together and to the substrate and wherein the coating does not bleed through the substrate. The roofing underlayment system of the present invention can impart a Class B or better (Class A) fire rating to a roof assembly.

Abstract: An asphalt coated structural article comprises a substrate having an ionic charge coated on one side with a layer of asphaltic material and coated on the other side with a coating having essentially the same ionic charge as the substrate. The present invention is a waterproofing barrier which may be used as a roofing underlayment for concrete files or to waterproof the basement walls of a building structure.
