Product Description

Thermobestos was a brand name for asbestos-containing pipe and block insulation marketed in the U.S. industrial market from approximately the 1940s through the late 1970s by Eagle-Picher Industries, Philip Carey Manufacturing Company, and related industry producers including Forty-Eight Insulations. Thermobestos pipe and block insulation was specified for high-temperature thermal insulation applications on steam piping, condensate piping, process piping, hot-fluid piping, boilers, turbines, condensers, evaporators, distillation columns, heat exchangers, and other heated industrial equipment.

Per publicly filed U.S. asbestos litigation, Thermobestos insulation was extensively installed across U.S. electric utility power plants, petroleum refineries, chemical plants, paper mills, steel mills, naval shipyards and Navy vessels, federal facilities including TVA hydroelectric and steam plants, Oak Ridge facilities, military bases, hospitals, universities, and a broad range of industrial worksites.

Eagle-Picher Industries and the Philip Carey Manufacturing Company / Celotex successor are corporate-trust-fund defendants under the 11 U.S.C. § 524(g) bankruptcy-trust system, having established asbestos personal-injury trusts to channel current and future asbestos personal-injury claims.

Asbestos Content

Plaintiffs alleged that Thermobestos pipe and block insulation contained substantial percentages of chrysotile asbestos (and in some product variants, amosite asbestos) as the principal thermal-insulating fiber. The asbestos content provided the heat-resistance and dimensional stability required for high-temperature service.

How Workers Were Exposed

Insulators, industrial maintenance mechanics, pipefitters, boiler tenders, and bystander workers were exposed to Thermobestos during multiple routine activities:

  • Installation — cutting Thermobestos pipe covering to fit, sawing block insulation, applying cements to seal joints
  • Removal and rip-out during major overhauls, repair work, and end-of-life equipment teardown — among the highest-fiber-release activities of the insulation trade
  • Repair and patch work during routine maintenance on damaged insulation
  • Adjacent-area exposure to other workers performing Thermobestos installation or removal

Plants Where Thermobestos Was Installed

Per publicly filed asbestos litigation testimony, Thermobestos was installed at:

  • TVA hydroelectric and steam plants across Tennessee, Kentucky, Mississippi, Alabama
  • U.S. electric utility plants nationwide
  • U.S. petroleum refineries including Gulf Coast and California refineries
  • Naval shipyards and Navy vessels of the asbestos era
  • Federal facilities including Department of Energy / Atomic Energy Commission Oak Ridge facilities
  • Major chemical plants — DuPont, Dow, Union Carbide, Eastman, Monsanto, and others
  • Paper mills, steel mills, and broader industrial facilities

If You Worked With or Around Thermobestos Insulation

If you worked as an insulator, industrial maintenance mechanic, pipefitter, boiler tender, plant operator, contractor, or in any other role around Thermobestos asbestos pipe and block insulation during the asbestos era — and have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related illness — you may have legal rights, including claims against the Eagle-Picher Industries and Celotex (Philip Carey) bankruptcy trusts.
