Two Or More Paper Layers Patents (Class 442/34)
  • Patent number: 8110512
    Abstract: A facing laminate for insulation products includes: a foil or metallized polymeric film sheet layer forming an inner layer of the laminate that is adapted be bonded directly to a surface of an insulation product; a paper composite sheet layer, which may include synthetic and/or inorganic fibers, forming an outer exposed layer of the laminate; and a scrim intermediate and bonded to the foil or metallized polymeric film sheet and paper composite sheet layers. The facing laminate may include a humectant and/or a water, oil, and/or grease repellant component. The paper composite sheet layer of the laminate exhibits greater dimensional stability and reduced wrinkling when the laminate is exposed to conditions of high humidity. Insulation products to be faced with this facing laminate include pipe insulation, duct board, duct wrap insulation, metal building insulation, and other building insulation products.

  • Patent number: 7425515
    Abstract: A multi-layer reflective insulation system for walls, ceilings, floors, roofs and similar applications includes a sheet of multi-layer reflective insulation from a roll product. The sheet of multi-layer reflective insulation is a laminate that includes first and second pliable sheet layers with reflective major surfaces and a separation media, intermediate opposed major surfaces of the first and second pliable sheet layers, that holds the first and second pliable sheet layers in a spaced apart relationship relative to each other. The separation media creates air space between the opposed major surfaces of the first and second pliable sheet layers for the enhanced reflection of incident radiation and the emission of radiation by a reflective surface of the product.

  • Patent number: 7259113
    Abstract: The present invention is directed to a scrim comprised of a plurality of warp and weft tapes, and more specifically to a woven scrim comprised of warp tapes and weft tapes, wherein the warp tapes are positioned in first and second planes to increase the warp coverage by at least 150% such that the resulting scrim material is impervious to light and further deters bunching of the warp tapes.

  • Patent number: 7132376
    Abstract: A multi-layer woven scrim, having two or more layers made of thermoplastic tapes, has its layers attached together by means of layer-connecting tapes interwoven with mutually perpendicular tapes of adjacent layers. The points of attachment may be at spaced intervals and in the machine or cross-machine directions. The scrim is flexible, dimensionally stable and has high tensile and tear strength. It can be coated and used as an industrial fabric.
