  • Dual-glass fibers and insulation products therefrom
    Patent number: 5536550
    Abstract: A glass fiber insulation product comprises irregularly-shaped glass fibers of two different glasses having differing coefficients of thermal expansion, with the irregularly-shaped dual-glass fibers exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material.
    Type: Grant
    Filed: March 16, 1995
    Date of Patent: July 16, 1996
    Assignee: Owens Corning Fiberglas Technology, Inc.
    Inventors: Ronald A. Houpt, Russell M. Potter, Tod D. Green, David P. Aschenbeck, Clarke Berdan, II
  • Fibrous glass insulation assembly
    Patent number: 5466504
    Abstract: An improved fibrous glass insulation assembly is disclosed. The insulation assembly includes at least one fibrous glass body enclosed by a vapor barrier plastic outer layer or by a bag or package. A desiccant is provided adjacent the fibrous glass body to remove moisture.
    Type: Grant

  • Method for determining binder content and degree of cure in a fibrous mat
    Patent number: 4609628
    Abstract: A method for measuring binder characteristics in a mat of binder coated mineral fibers, the binder having a first cure indicator constituent, the amount of which changes at a first rate as the binder is cured, and a second cure indicator constituent, the amount of which changes at a second rate, different from the first rate, as the binder is cured, comprising radiating the mat and binder with first, second, third and fourth wavelengths of electromagnetic radiation, the first wavelength being absorbed by the binder including the first cure indicator constituent, the second wavelength being a reference for the first wavelength and being not absorbed by the binder or the cure indicator constituents, the third wavelength being absorbed by the binder including the second cure indicator constituent, and the fourth wavelength being a reference for the third wavelength and being not absorbed by the binder or the cure indicator constituents, and further sensing the amount of energy of the first, second, third and fou
