Asbestos Felt (Flintkote Company)
Asbestos felt manufactured by the Flintkote Company was a widely used industrial and construction underlayment material produced from approximately 1940 through 1983. As awareness of asbestos hazards grew through the latter decades of that production window, litigation records document that workers exposed to this product during its manufacture, installation, and removal faced significant health risks from chrysotile asbestos fibers. No dedicated asbestos bankruptcy trust fund currently exists for Flintkote-related asbestos felt claims in this product category, meaning that legal remedies for affected individuals are pursued primarily through civil litigation.
Product Description
Asbestos felt was a flexible sheet material used extensively as an underlayment beneath floor tiles, resilient flooring, and other surface installations in industrial, commercial, and residential settings. The Flintkote Company, a major manufacturer of building and construction materials throughout the mid-twentieth century, produced asbestos felt as part of a broader line of flooring and roofing products. The material was valued in the construction trades for its dimensional stability, moisture resistance, and durability under heavy foot traffic and industrial loads.
During the decades of peak production — roughly 1940 through 1983 — asbestos felt was considered a reliable, cost-effective substrate. It was sold in rolls and cut to fit sub-floor surfaces before finish flooring materials were laid on top. Because the Flintkote Company operated across multiple product lines and distributed materials nationally, asbestos felt bearing the Flintkote name appeared in factories, warehouses, schools, hospitals, and commercial buildings throughout the United States.
Production of asbestos-containing felt largely ceased or was phased out following increased regulatory scrutiny by the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) during the late 1970s and early 1980s. The Asbestos Hazard Emergency Response Act (AHERA), enacted in 1986, further codified federal recognition of asbestos as a significant public health concern in building materials.
Asbestos Content
Flintkote asbestos felt contained chrysotile asbestos, the most commonly used form of asbestos in American manufacturing during the twentieth century. Chrysotile, sometimes called “white asbestos,” is characterized by its curly, flexible fiber structure and was incorporated into felt products as a reinforcing agent and binder. The presence of chrysotile gave the felt material its characteristic tensile strength and resistance to deterioration under moisture and mechanical stress.
Chrysotile asbestos fibers, while sometimes described as less biopersistent than amphibole fiber types, are nonetheless classified as a known human carcinogen by the International Agency for Research on Cancer (IARC) and regulated as a hazardous substance under OSHA standards. OSHA’s current permissible exposure limit (PEL) for asbestos is 0.1 fibers per cubic centimeter of air as an eight-hour time-weighted average, reflecting the serious occupational health risks associated with all asbestos fiber types, including chrysotile.
In asbestos felt, chrysotile fibers were typically bound within the felt matrix. However, cutting, trimming, abrading, or disturbing the material — particularly in older or deteriorating condition — could release respirable fibers into the surrounding air. Once airborne, chrysotile fibers can be inhaled deeply into lung tissue, where they may cause irreversible fibrotic and malignant disease over time.
How Workers Were Exposed
Industrial workers generally represent the primary trade category documented in exposure claims associated with Flintkote asbestos felt. The nature of exposure varied depending on a worker’s role and proximity to the material during its lifecycle.
During installation, workers cut asbestos felt rolls to fit sub-floor dimensions using utility knives, shears, or saws. Cutting and trimming operations generated visible dust and fine fiber particles. In poorly ventilated industrial spaces — factories, warehouses, and production facilities — these fibers could remain suspended in air for extended periods, increasing the duration and concentration of potential exposure.
During manufacturing and handling, workers in production facilities where asbestos felt was fabricated were exposed to raw chrysotile fibers at various stages of the manufacturing process, including fiber mixing, sheet formation, and finishing. Litigation records document that industrial workers employed at facilities producing or processing asbestos-containing materials, including felt products, alleged that they were not adequately informed of the health hazards associated with asbestos exposure, nor provided with appropriate respiratory protective equipment.
During renovation and demolition, workers tasked with removing old flooring in industrial buildings encountered asbestos felt beneath existing tile or resilient flooring. Removal operations — including scraping, grinding, and mechanical demolition — are among the most fiber-releasing activities associated with asbestos-containing flooring underlayment. Workers who performed these tasks on aging Flintkote asbestos felt products, particularly in buildings constructed or renovated between 1940 and the early 1980s, may have faced high-intensity, short-duration exposures that are associated with elevated disease risk.
Plaintiffs alleged in litigation proceedings that the Flintkote Company knew or should have known of the dangers posed by chrysotile asbestos in its felt products well before adequate warnings were provided to end users, installers, and industrial workers handling the material. Litigation records document claims that the company failed to label products with appropriate hazard warnings and did not implement engineering controls or recommend respiratory protection during periods when the health hazards of asbestos were already established within the scientific and industrial hygiene literature.
Documented Trust Fund / Legal Options
Trust Fund Status: No dedicated asbestos bankruptcy trust fund currently exists specifically for Flintkote asbestos felt claims in the floor-tile product category. While the Flintkote Company did establish an asbestos-related bankruptcy trust — the Flintkote Asbestos Settlement Trust — the availability and scope of claims through that trust depend on specific product eligibility criteria and documented exposure circumstances. Individuals with potential claims should consult qualified asbestos litigation counsel to determine whether their specific exposure history and disease diagnosis meet current trust filing requirements.
Civil Litigation: Because trust recovery options may be limited or unavailable for certain claimants, litigation records document that individuals diagnosed with asbestos-related diseases following exposure to Flintkote asbestos felt have pursued civil litigation against the manufacturer and related parties. Plaintiffs alleged causes of action including negligence, failure to warn, strict products liability, and breach of warranty.
Compensable Diseases: Asbestos-related diseases for which claims have been documented in connection with chrysotile-containing products such as asbestos felt include mesothelioma, lung cancer, asbestosis, and other asbestos-related pleural conditions. Mesothelioma — a rare and aggressive malignancy of the pleural or peritoneal lining — is considered a signature asbestos disease and is associated with significant legal recoveries in documented litigation.
Steps for Affected Workers: Industrial workers who handled, installed, or removed Flintkote asbestos felt between 1940 and 1983 and who have received a diagnosis of an asbestos-related disease are encouraged to:
- Document their work history, including specific job sites, employers, and dates of exposure
- Obtain complete medical records confirming their diagnosis
- Consult an attorney experienced in asbestos litigation to evaluate available legal avenues, including any applicable trust claims or civil actions
- Act promptly, as statutes of limitations governing asbestos claims vary by state and begin running from the date of diagnosis or discovery of the disease
Legal options for individuals harmed by exposure to Flintkote asbestos felt remain available through the civil court system. Affected workers and their families should seek legal counsel to understand the specific remedies applicable to their circumstances.
