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: A fire resistant fabric material comprising a substrate having an ionic charge which is coated with a coating having essentially the same ionic charge. The coating consists essentially of a filler material comprising clay and a binder material. The substrate is preferably fiberglass, the filler material may further comprise at least one additional filler selected from the group consisting of decabromodiphenyloxide, antimony trioxide, fly ash, charged calcium carbonate, mica, glass microspheres and ceramic microspheres and mixtures thereof and the binder material is preferably acrylic latex.

Abstract: There is provided a hip, ridge, or rake shingle, which includes a shingle panel and at least one rigid back member. The shingle panel has a substantially planar lower surface. The at least one rigid back member has a length substantially the same as or greater than the length of the shingle panel. The rigid back member is attached to the substantially planar lower surface of the shingle panel. The rigid back member includes a step in thickness in a cross-sectional plane perpendicular to the substantially planar lower surface and parallel to the longitudinal axis of the rigid back member. In addition, the thickness of the rigid back member at the high level of the step is greater than the thickness of the rigid back member at one of its ends. There is also provided an asphaltic adhesive including from about 62% to about 99% by weight of an asphalt cement; from about 0.5% to about 15% by weight of a first thermoplastic having a glass-transition temperature in the range from about 190° F.

Abstract: A structural article comprises a substrate having an ionic charge which is coated with a coating having essentially the same ionic charge. The coating consists essentially of a filler material and a binder material. The substrate is preferably fiberglass, the filler is selected from the group consisting of fly ash, charged calcium carbonate, ceramic microspheres and mixtures thereof and the binder material is preferably acrylic latex. The substrate is preferably bonded together using a mixture of urea formaldehyde and standard acrylic. In a preferred embodiment, the coating comprises nearly 85% of the structural article and a filler which is approximately 50% fly ash and 50% calcium carbonate comprises approximately 85% to 95% of the coating.
