Thorpe Insulation Company (J.T. Thorpe & Son, Inc.) was a major West Coast asbestos insulation contractor that supplied and installed asbestos insulation materials aboard Navy ships and at West Coast naval shipyards throughout the mid-twentieth century. Unlike asbestos product manufacturers, Thorpe was a specialty insulation contractor — a company that supplied asbestos pipe covering, asbestos block insulation, asbestos cloth, and related materials and provided workers to install those materials during ship construction and overhaul. Thorpe operated extensively on West Coast naval vessels and shipyards, and is documented in the publicly filed asbestos litigation corpus as a named Navy asbestos insulation contractor alongside Metalclad Insulation Corporation, with asbestos pipe covering supply documentation, asbestos mud powder documentation, and formal defendant listings in the national asbestos docket.

Documented Asbestos in Thorpe Insulation Navy Work

West Coast Ships and Shipyards — Thorpe’s Documented Territory

“…Thorpe (CA) - West Coast Ships and Shipyar[ds]…” — Thorpe Insulation Company, identified as a California-based entity, is specifically documented as operating on West Coast ships and at West Coast shipyards in the publicly filed asbestos litigation corpus. This geographic characterization — “West Coast Ships and Shipyards” — establishes Thorpe’s documented area of operation: the Pacific Fleet ships and the West Coast naval shipyards (Mare Island, Hunters Point, Long Beach, Puget Sound) where asbestos insulation installation and removal work was performed throughout the Cold War.

Named Defendant — With Raybestos-Manhattan

“…RAYBESTOS-MANHATTAN, THORPE INSULATION COMPANY, TOS[…]…” — Thorpe Insulation Company is named in the corpus as a formal defendant alongside Raybestos-Manhattan (a major asbestos textile and packing manufacturer) in asbestos litigation proceedings. The formal naming of Thorpe Insulation Company as a defendant alongside major product manufacturers establishes Thorpe’s recognized liability status in the national asbestos docket — as a contractor whose asbestos installation work created documented asbestos exposure for Navy shipyard workers and ship crews.

Asbestos Pipe Covering — Supply Documentation

“…Metalclad and Thorpe supplied asbestos pip[e covering]…” — Thorpe Insulation Company and Metalclad Insulation Corporation are jointly documented as suppliers of asbestos pipe covering in the Navy shipyard context. The pairing of Thorpe and Metalclad — two of the major West Coast asbestos insulation contractors — establishes the competitive and collaborative environment in which these companies supplied asbestos pipe covering to Navy shipyards. Workers who installed Thorpe-supplied asbestos pipe covering were directly exposed to the asbestos fiber released during cutting, fitting, and application.

“…Of the outside insulation suppliers, Thorp[e]…” — testimony or documentation identifying Thorpe among the outside insulation suppliers — contractors who brought asbestos insulation materials and workers into the shipyard from outside the yard’s regular workforce — appears in the corpus. The “outside insulation supplier” characterization establishes Thorpe’s role as a specialty insulation contractor operating within naval shipyard environments.

Asbestos Mud Powder — Named Product

“…asbestos mud powder, THORPE INSULATION C[OMPANY]…” — Thorpe Insulation Company is specifically associated with asbestos mud powder in the corpus. Asbestos insulating cement (commonly called “asbestos mud”) was a mixture of asbestos fiber and binding agent mixed to a paste consistency for application to irregular equipment surfaces, fitting covers, and valve bodies — any surface where pre-formed insulation sections could not be used. Mixing and applying asbestos mud powder created heavy airborne asbestos fiber during the dry-mixing phase, and the application of wet cement to hot equipment surfaces released additional fiber.

Full Insulation Range — Asbestos Cloth and Amosite

“…all types of insulation, asbestos cloth, amo[site pipe covering]…” — documentation establishing that Thorpe Insulation supplied all types of asbestos insulation — including asbestos cloth and amosite (brown asbestos) pipe covering — appears in the corpus. The identification of amosite specifically — the most hazardous commercially used asbestos fiber type — establishes that Thorpe’s Navy shipyard insulation work involved the highest-risk asbestos materials in addition to the more common chrysotile (white asbestos) pipe covering.

Non-Navy Testimony Context — Navy Testimony Parallel

“…the ship, Non-Navy testimony, Plaintiffs…” — documentation distinguishing Navy ship testimony from non-Navy testimony in the context of Thorpe Insulation work appears in the corpus, consistent with the multi-venue litigation structure in which Thorpe was a defendant for both Navy ship insulation work and shore facility insulation work.

Who Was Exposed to Thorpe Insulation Work

  • Thorpe Insulation Company workers — the pipecoverers, laggers, and insulation mechanics employed by Thorpe who installed asbestos pipe covering, applied asbestos mud, and handled asbestos cloth throughout their work on Navy vessels and at naval shipyards
  • Shipyard tradespeople — workers of all other trades (pipefitters, electricians, shipfitters) who worked in enclosed ship spaces where Thorpe was simultaneously performing asbestos insulation installation
  • Navy crew aboard ships under overhaul — personnel who remained aboard ships during Thorpe’s insulation work and were exposed to airborne asbestos fiber from Thorpe’s operations

Navy veterans who served aboard ships where Thorpe Insulation Company performed asbestos insulation work, and civilian shipyard workers who worked alongside Thorpe insulators at West Coast naval shipyards, who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease, may qualify for:

  • VA presumptive service connection under 38 CFR § 3.309(d) for veterans with documented service aboard vessels where Thorpe Insulation performed Navy ship insulation work
  • Longshore and Harbor Workers’ Compensation Act (LHWCA) for workers employed by Thorpe Insulation Company or by West Coast naval shipyards where Thorpe operated
  • Civil claims against Thorpe Insulation Company successors and J.T. Thorpe Trust based on Thorpe’s role as a Navy asbestos insulation contractor

Key documents:

  • DD-214 or service records — documenting service aboard West Coast Navy ships undergoing insulation work
  • Employment records — Thorpe Insulation Company or shipyard employment records documenting insulation installation work at naval facilities
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
