FI Insulating Cement

Product Description

FI Insulating Cement was a refractory insulating cement manufactured by Fibreboard-Pabco during a documented production window spanning 1963 through 1966. Refractory cements of this type were engineered to withstand extreme temperatures and were commonly installed in industrial environments where thermal management was critical. These settings included furnaces, kilns, boilers, and other high-heat industrial equipment that required durable, heat-resistant insulating materials capable of maintaining structural integrity under prolonged thermal stress.

Fibreboard-Pabco was a manufacturer with roots in both the fibreboard and building materials industries, and its Pabco product line represented a broad range of industrial and construction materials produced during the mid-twentieth century. The FI Insulating Cement product was one of several specialty refractory materials the company brought to market during this period, targeting industrial facilities that demanded reliable thermal insulation as part of their core operations.

Although FI Insulating Cement was manufactured only during a relatively narrow four-year window, its use in industrial installations meant that the product could remain in place — and continue to pose potential exposure risks — for many years or even decades after initial application. Refractory cements, once applied to industrial equipment, were typically disturbed during maintenance, repair, or demolition activities long after the original installation date.


Asbestos Content

FI Insulating Cement contained chrysotile asbestos as a component of its formulation. Chrysotile, sometimes referred to as white asbestos, is a serpentine mineral fiber that was widely incorporated into cement, insulation, and refractory products throughout the mid-twentieth century because of its heat resistance, binding properties, and relative availability in commercial quantities.

In refractory cement applications, chrysotile asbestos served a functional role: the fibers reinforced the cement matrix, improved its resistance to thermal cracking, and contributed to the material’s overall durability under high-temperature cycling. These properties made asbestos-containing refractory cements an appealing choice for manufacturers and industrial engineers during this era, when the full scope of asbestos-related health hazards was not yet widely communicated to workers or regulated by federal agencies.

Chrysotile asbestos, while generally considered less potent than amphibole fiber types such as crocidolite or amosite, is nonetheless classified as a known human carcinogen by the International Agency for Research on Cancer (IARC) and is subject to strict regulatory controls under OSHA’s asbestos standards and the Asbestos Hazard Emergency Response Act (AHERA). Inhalation of chrysotile fibers has been associated with mesothelioma, asbestosis, lung cancer, and other serious respiratory diseases.


How Workers Were Exposed

Industrial workers who handled, mixed, applied, or worked in proximity to FI Insulating Cement during its period of production and use were at risk of asbestos fiber inhalation. Refractory cement products, by their nature, were applied and disturbed in conditions that could readily generate airborne dust.

The mixing of dry cement powders was among the highest-risk activities. Before application, workers would often combine powdered refractory cement with water or other materials to create a workable paste. This dry-mixing process — or the handling of bags of unmixed product — could release significant quantities of chrysotile fiber-containing dust into the breathing zone of workers performing the task and those working nearby.

Application of the mixed cement to boilers, furnaces, kilns, and related industrial equipment also presented exposure risk, particularly when workers troweled or packed the material into joints, seams, or surfaces. Trimming and shaping the applied cement while it cured, or chipping and removing old refractory cement during maintenance and repair cycles, could disturb dried material and release fibers that had been locked into the hardened cement matrix.

Workers involved in the maintenance or demolition of equipment insulated with FI Insulating Cement faced exposure risks even if they had never directly handled the product in its original form. Removing, chipping, or breaking apart aged refractory cement — particularly cement that had been subjected to repeated heat cycling and had become friable over time — could release concentrated amounts of chrysotile fibers. Industrial workers in facilities where this product was installed, including those in adjacent trades or work areas, may have inhaled fibers disturbed by others without any direct contact with the cement itself.

Because FI Insulating Cement was used in refractory applications, exposure was concentrated in industrial environments such as steel mills, foundries, chemical plants, refineries, and other heavy industrial settings where high-temperature equipment was a central feature of facility operations.


FI Insulating Cement is a Tier 2 product for legal purposes. No dedicated asbestos bankruptcy trust fund has been established specifically to compensate individuals harmed by exposure to this product. Compensation claims related to FI Insulating Cement are pursued through the civil litigation system rather than through a trust fund claims process.

Litigation records document that plaintiffs have brought claims against Fibreboard-Pabco and successor entities in connection with asbestos-containing products manufactured and distributed under the Pabco brand. Plaintiffs alleged that the company manufactured, marketed, and sold asbestos-containing materials, including refractory and insulating products, without adequately warning workers of the known health hazards associated with asbestos fiber inhalation. Plaintiffs further alleged that exposure to these products caused diagnosed conditions including mesothelioma, lung cancer, and asbestosis.

Litigation records document that asbestos personal injury lawsuits involving Fibreboard-related products have been filed across multiple jurisdictions throughout the United States. Plaintiffs alleged that corporate knowledge of asbestos hazards predated adequate warnings to the workers who encountered these products in the field.

Individuals who may have legal claims related to FI Insulating Cement include:

  • Industrial workers who mixed, applied, or removed FI Insulating Cement or similar Pabco refractory products between 1963 and 1966 or in subsequent years during maintenance activities
  • Workers who were present in industrial facilities during installation, repair, or removal of this product and were exposed to airborne dust
  • Family members of workers who may have experienced secondary exposure through contaminated work clothing

Because no trust fund exists for this product, compensation is available only through civil litigation. Statutes of limitations apply to asbestos personal injury claims, and the applicable deadline is typically measured from the date of an asbestos-related diagnosis rather than the date of original exposure. Anyone who believes they may have been exposed to FI Insulating Cement and has since received a diagnosis of mesothelioma, lung cancer, asbestosis, or another asbestos-related disease should consult with a qualified asbestos litigation attorney promptly to evaluate their legal options and preserve their right to seek compensation.
