  • Fire hydrant thermal and acoustic insulation material
    Patent number: 5955386
    Abstract: An open weave, air permeable fiber pad is formed from a plurality of compressed, interlocked fiber strands. A non-uniform, three dimensional grid of spaced apart, expandable graphite particles are secured at randomly spaced apart intervals to individual fiber strands with a particle distribution density sufficient to form a barrier to air flow through a defined area of the fiber pad when exposed to a source of heat causing the expandable graphite particles to be converted from their normal volume to a heat-activated, substantially expanded volume.
    Type: Grant
    Filed: November 25, 1998
    Date of Patent: September 21, 1999
    Inventor: Bill D. Horton
