  • Publication number: 20220048284
    Abstract: Unique insulation articles including corrosion inhibitors and methods of producing the same are disclosed. One exemplary embodiment is an article of manufacture comprising an insulation mat comprising a cured combination of a plurality of randomly oriented fibers and a binder, the insulation mat extending between a first surface and a second surface, a veil attached to the first surface, the veil structured to inhibit physical movement of the cured combination through the veil, a metal sheet attached to the second surface by a water-containing adhesive contacting the metal sheet and the second surface, and a corrosion inhibitor composition deposited on the cured combination of the insulation mat, the corrosion inhibitor composition being effective to modify toward neutral a pH of the cured combination in contact with water from the water-containing adhesive.

  • Patent number: 10087634
    Abstract: A method includes providing a production line configured for continuous fabrication of polymer or predominantly polymer roofing boards by setting and expansion of precursor materials on a conveyor. A first polymer or predominantly polymer material foam precursor is dispensed to the production line, and allowed to rise and at least partially set to form a foam core layer for an insulation board, the foam core layer for the insulation board having a first density. A second polymer or predominantly polymer material foam precursor is dispensed to the production line and allowed to rise and set to form a core layer for a cover board, the foam core layer for the cover board having a second density greater than the first density. The combined thickness of the foam core layer for the insulation board and the core layer for the cover board is set by constraining the expansion of the combined foam precursors using a downstream forming conveyor disposed above the rising foam precursors.

  • Patent number: 8490911
    Abstract: Provided is a method of rolling two single-ply membrane sheets having seam tape applied along one edge, for easy transport. The method comprises placing a first sheet on top of a second sheet, with the seam tape edge of each of said sheets being at the same end. The sheets are placed so that the seam tape of the first sheet does not overlay the seam tape of the other sheet. The two sheets can then be easily and quickly rolled for transport to a job site.

  • Patent number: 8479467
    Abstract: A prefabricated roofing panel composite includes a prefabricated cover board having a high-density polymer or predominantly polymer material core layer having a density between 6 lbs/ft3 and 25 lbs/ft3 and an insulation board that has a low-density polymer or predominantly polymer material foam core layer having a density less than or equal to about 2 lbs/ft3. The cover board may have a waterproofing membrane forming the top major surface of the cover board. The low-density foam core layer of the insulation board may be formed with the high-density core layer of the cover board being currently or subsequently formed over and bonded to a top major surface of the low-density foam core layer in the same operation or preformed insulation boards may be fed into a production line with the high-density core layer of the cover board being formed over and bonded to top major surfaces of the low-density foam core layers of the insulation boards.

  • Patent number: 8056371
    Abstract: This invention involves apparatus and methods for making fibers by passing a molten material like glass, polymer, etc. through orifices or tips in a fiberizing bushing and then cooling the molten material coming from the tips and newly formed fibers using cooling tubes. The cooling tubes are made from precious metals and various alloys comprising precious metals, nickel and one or more of titanium, chromium, molybdenum, etc. The one or more fins attached to the top surface of a hollow tube to make the cooling tubes contain spaced apart gaps, notches and/or slots extending from the top edge of the fin to prevent warping of the fins and to make the cooling tube more bendable, adjustable during the operation of making fibers from molten material.
