  • Patent number: 8156704
    Abstract: A bundle of laminated shingles is provided. The bundle includes a plurality of shingles having an overlay laminated with an underlay. The overlay has a tab portion with cutouts normally exposed on a roof and a headlap portion. The headlap portion has a lower zone adjacent the tab portion and an upper zone adjacent said lower zone. The lower zone has substantially no granules adhered thereto. The bundle defines a central area that substantially encompasses the lower zones of the stacked shingles. The shingles are stacked such that every other of the shingles is inverted and turned 180 degrees relative to an adjacent shingle. The shingles are double-layered, wherein the lack of granules in the lower zones of the stacked shingles results in the central area of the bundle having a height substantially identical to a height of a remainder of the bundle outside of the central area.

  • Patent number: 7268092
    Abstract: A composite part made from a sheet molding compound is disclosed as having improved characteristics over traditional sheet molding compound composite parts. The fibrous material is introduced as a veil layer adjacent a paste layer, the veil flows well during the molding process. The improved flow and surface characteristics of a composite part are attributed to the elongation of the veil during molding and to the improved filling capabilities.

  • Patent number: 7252729
    Abstract: A method of forming a molding mat formed bundles of reinforcing fibers and bonding materials is provided. The reinforcing fibers are preferably wet use chopped strand glass fibers (WUCS). The bonding materials may be any thermosetting material having a melting point less than the reinforcing fiber. The molding mat may be formed by partially opening the wet use chopped strand glass fibers and filamentizing the bonding materials, blending the reinforcement and bonding fibers, forming the reinforcement and bonding fibers into a sheet, and bonding the sheet. During bonding, the sheet is heated to a temperature above the melting point of the bonding fibers but below the temperature of the glass fibers. The molding mat thus formed may be used as a reinforcement material in sheet molding compounds.

  • Patent number: 7251959
    Abstract: A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment. The neutralization system introduces a base solution to a washwater solution when the pH of the washwater solution contained in a closed loop washwater recovery system falls below about 8.5, thereby substantially reducing the corrosion rate of the components of the equipment associated with acidic polyacrylic acid binder, maleic acid cobinder or maleic anhydride cobinder and washwater solution. A closed-loop hoodwall washwater recovery system may also be introduced in addition to the neutralization system that allows for the recovery and reuse of polyacrylic acid binder and maleic acid cobinder or maleic anhydride cobinder with a minimal amount of base solution, thereby minimizing degradation of insulation properties of polyacylic acid bound glass fiber products.

  • Patent number: 7238408
    Abstract: An asphalt-based roofing material includes a coating having a top portion containing a mixture of asphalt and igneous and/or metamorphic rock particles, while the mat portion of the coating contains a mixture of asphalt and a filler which contains less than 10% igneous and/or metamorphic rock particles. In other embodiments, the top portion but not the bottom portion of the coating meets or exceeds a pliability standard, passes a weathering performance test, or has a high solar reflectance. In another embodiment relating to a laminated roofing material, the top portion but not the bottom portion has viscoelastic properties effective to prevent the coating from sticking to an adjacent shingle in a bundle. The invention also relates to a continuous process of applying first and second coatings to a mat for manufacturing a roofing material.

  • Patent number: 7222645
    Abstract: An insulated duct-wrap insulating product for an air duct that incorporates a wicking media to transport condensed water on the duct surface to be evaporated into the atmosphere. A wicking fabric, or fibrous media, incorporated as part of the insulating duct wrap is in contact with the metal air duct surface. A portion of the wicking fabric extends into the interior of the air duct, typically through joints in the duct system. When water vapor condenses on the air duct surface it is transported by the wicking fabric and evaporated from the wick surface within the air stream being transported by the ducting system.

  • Patent number: 7211530
    Abstract: A conformable veil is formed by impregnating a random mat of glass fibers formed with a polystyrene-based resin. The veil is then introduced between two layers of a sheet molding compound resin paste and compacted to form a compacted sheet. The compacted sheet is then introduced to a mold and molded to form a soft, flexible sheet molding composite part having good resin and fiber distribution. Resin and fiber distribution of the present invention is improved because the polystyrene-based resin is soluble in the sheet molding compound resin paste and allows the plurality of fibers to flow freely within the resin paste during the molding process.

  • Patent number: 7168272
    Abstract: The present invention relates to a composite fabric wherein a plurality of small tows are intermittently spaced between large tows forming channels. The channels formed by spacing the between the large tows thereby forming ridges. The irregular thickness that results from the ridges provides flow channels during resin infusion of the fabric. The flow channels permit resin to flow evenly and quickly through the fabric, which results in shorter processing time and a more consistent resin distribution, decreasing the likelihood of resin starved areas within the cured laminate.
