  • Patent number: 8828892
    Abstract: The invention pertains to a drywall tape having a nonwoven fabric and a reinforcing scrim, wherein the nonwoven fabric has chopped glass fibers laid flat in the nonwoven fabric, the fibers being substantially straight, random laid and bonded to one another to resist forces exerted in random directions, and the reinforcement scrim has elongated reinforcing strands of low profile thickness joined against a side of the nonwoven fabric, such that the scrim and the nonwoven fabric reinforce each other, and reinforce a joint compound in which the drywall tape is imbedded.

  • Publication number: 20100147449
    Abstract: A method of reinforcing a structural support, includes applying a reinforcement system comprising an AR-glass fibrous layer embedded in an inorganic matrix to the structural support. The AR-glass fibrous layer has a sizing applied thereon, and a resinous coating applied is applied over the sizing. The inorganic matrix is adherent to the resinous coating and the resinous coating is adherent to the sizing.

  • Patent number: 7615504
    Abstract: A cementitious board and methods of making the same are disclosed by a cementitious board including a cementitious core, a plurality of warp yarns and weft yarns and a coating applied to produce a coating weight distribution ratio of less than about 2.0:1, based upon the weight of the resinous coating of the weft yarns, over the weight of the resinous coating on the warp yarns.

  • Patent number: 7615178
    Abstract: Fabric and reinforcements are provided by this invention which, in a first embodiment, include a plurality of warp yarns having a first twist (turns/inch) and a plurality of weft yarns having a second twist which is greater than the first twist. A coating is applied over a substantial portion of the warp and weft yarns after they are assembled or laid together, so as to produce a weight distribution ratio of less than about 2.0:1, based upon the weight of the resinous coating of the weft yarns over the weight of the resinous coating on the warp yarns. This can be achieved, in substantial part, due to the difference in the twist ratios of the warp and weft yarns, which difference permits a more uniform coating to be applied. Further embodiments of this invention include a cementitious board and methods of making a coated fabric and cementitious board.
