Abstract: Disclosed herein is a flooring underlayment membrane, and associated methods of manufacturing and installing such a membrane, comprising upper and lower nonwoven fiber layers. In one embodiment, the flooring underlayment membrane constructed as disclosed herein may comprise a first nonwoven fiber material, and a second nonwoven fiber material and at least one layer of extrudable thermoplastic resin disposed between and bonding the first and second nonwoven fiber materials.

Abstract: Roofing material consists essentially of a substrate, a hot melt material applied to one side of the substrate, an asphalt material coating the other side of the substrate and roofing granules disposed on said asphalt material coated on the substrate. The hot melt material may be polyethylene, polyethylene-vinyl acetate, polypropylene, polyvinylidene chloride, polyester, nylon and mixtures thereof. The asphalt material may include non-asphaltic filler.

Abstract: A fire resistant slipsheet in roll form includes a fiber mat having first and second sides and a coating containing expandable graphite, a filler, and a binder. The coating is coated on at least one of the first and second sides of the fiber mat, and a single layer of the slipsheet achieves a Class A rating when tested according to UL 790 and/or ASTM E-108 Standard Test Methods for Fire Tests of Roof Coverings. A fire resistant roofing system and a method for installing a fire resistant roofing system that achieves a Class A rating when tested according to UL 790 and/or ASTM E-108 Standard Test Methods for Fire Tests of Roof Coverings is also provided.

Abstract: Self-supporting scrim or web structure, which is readily thermopleated, is provided for use in filter applications. The self-supporting scrim has very high porosity. When pleated and deployed for filter applications, the scrim or web structure retains the shape of pleats and contributes minimally to airflow resistance. The scrim or web structure is fabricated from synthetic fibers and latex binders using a wet laid process.

Abstract: A structural article comprises a substrate having an ionic charge coated on one side with a coating having essentially the same ionic charge and covered on the other side with a water vapor impermeable material selected from the roof consisting essentially of metal foils and preformed plastic films. The coating consists essentially of a filler material and a binder material and the binder material bonds the filler material together and to the substrate. The water vapor impermeable material is attached to the coated substrate with an adhesive. In additional embodiments, the substrate is coated on both sides with a coating having essentially the same ionic charge and the article so coated is then covered on one or both sides with the water vapor impermeable material.

Abstract: Roofing material is improved by adhering to at least part of its lower surface a backing material consisting essentially of a fiber component and a binder component. Acceptable fibers include polyester, glass and woodpulp. In a preferred embodiment, the fiber component is a mixture of polyester and glass fibers and the binder is a latex binder.

Abstract: An improved dimensionally stable backing web is disclosed, especially for resilient flooring product and linoleum, comprising cellulosic fiber, a binder, antioxidant, fungicide and glass fiber, as well as optionally dyes or pigments, surfactants and vulcanizing agents. Also optionally present are calcium silicate mineral fiber or synthetic fiber, such as polyolefin, polyester, nylon, acrylic or modacrylic fiber, a cellulose acetate or mixtures thereof. The binder can be a natural rubber or synthetic rubber latex or mixtures thereof. The synthetic rubber latex is preferably selected from the following: styrene-butadiene; carboxylated styrene-butadiene, polyacrylic ester, polyvinyl acetate; polyisobutylene, a copolymer formed from vinyl acetate monomers and acrylic acid; polychloroprene, acrylonitrile-butadiene or carboxylated acrylonitrile-butadiene; polyurethane; a copolymer of ethylene and vinyl acetate; or other elastomeric copolymers.
