Patent number: 8110512Abstract: 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.Type: GrantFiled: May 21, 2010Date of Patent: February 7, 2012Assignee: Johns ManvilleInventors: Anthony Edward Moore, Melvin Glenn Mitchell, Monroe William Shumate, Edward Albert Bright, James W Stacy

Patent number: 7425515Abstract: 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.Type: GrantFiled: January 10, 2005Date of Patent: September 16, 2008Assignee: Johns ManvilleInventors: Thomas J. Fellinger, Craig Sakata, Jeffrey D. Reinsma, John Brooks Smith, N. Douglass Fast, Marcus V. A. Bianchi, Anthony E. Moore

Patent number: 7132376Abstract: 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.Type: GrantFiled: February 24, 2004Date of Patent: November 7, 2006Assignees: Interwrap, Inc., IBCO SRLInventor: Mohamed Abdel Aziz Rashed

Publication number: 20040152379Abstract: A novel gypsum wallboard having a textile reinforcing material embedded within a gypsum core together with randomly oriented chopped glass fibers, as well as a novel process for constructing such gypsum wallboards.Type: ApplicationFiled: January 30, 2003Publication date: August 5, 2004Inventors: George C. McLarty, Andrew D. Child, Johan Gerlich
