North American Refractories (NARCO): Asbestos History & Liability

NARCO: Supplying High-Temperature Refractories to American Industry

North American Refractories Company was established to serve one of American heavy industry's most fundamental needs: the lining and protection of the extreme-heat environments within which steel, glass, cement, and non-ferrous metals are produced. Refractory materials — bricks, mortars, castable concretes, and pre-formed shapes designed to withstand temperatures that would destroy ordinary construction materials — are essential components of every blast furnace, basic oxygen furnace, electric arc furnace, glass-melting tank, rotary cement kiln, and high-temperature chemical reactor in industrial production.

NARCO supplied refractory products to some of the largest and most demanding industrial facilities in the United States throughout the mid-twentieth century. Steel mills in Pittsburgh, Cleveland, Gary, and Birmingham used NARCO bricks and mortars to line their blast furnaces and steelmaking vessels. Glass manufacturers from Ohio to New Jersey relied on NARCO refractory products to construct and maintain the furnaces in which raw silica and additives were melted into molten glass. Cement producers, copper smelters, aluminum smelters, and chemical plants across the country were all customers for NARCO's extensive product catalog.

What made NARCO's products so valuable to these industries — and so hazardous to the workers who installed and maintained them — was the incorporation of asbestos fibers into many of the company's refractory mortars, cements, and specialty high-temperature compounds. Asbestos added structural integrity and thermal stability to refractory mortars, helping them bond effectively with refractory bricks and resist cracking under the extreme and often cyclically varying temperatures of industrial furnace operation. The resulting products were highly effective from an engineering standpoint, but they created serious health hazards for every worker involved in their installation, maintenance, and eventual demolition.

NARCO's operations extended across multiple manufacturing plants in the United States. While the company lacked the towering public profile of the steel mills and glass manufacturers it supplied, within its own industry it was a significant and well-established presence. Its products were specified by engineers and purchasing departments at major industrial corporations, and NARCO sales representatives and technical staff worked closely with customers to design refractory systems for specific high-temperature applications. The company's reach into major industrial sectors ensured that when its asbestos-containing products were installed, they were placed into environments where large numbers of workers would be exposed over many years of service.

Asbestos in NARCO Refractory Bricks, Mortars, and High-Temperature Compounds

The asbestos content of NARCO's refractory product lines was not limited to a single product type or application. Asbestos appeared in multiple categories of NARCO materials, including high-temperature mortars used to set refractory brick, castable refractory compounds poured into complex shapes, insulating refractory boards used as backup insulation behind hot-face brick, and specialty cements used for sealing joints and repairing damaged refractory linings.

High-temperature refractory mortars were perhaps the most significant source of worker exposure among NARCO's product lines. These mortars — used as a bonding agent between individual refractory bricks during the construction or repair of furnace linings — were typically applied by hand or with hand tools by bricklayers and refractory installers working in close proximity to the mortar material. When the dried mortar was disturbed during subsequent repairs, demolition, or relining work, asbestos fibers became airborne. Workers performing these tasks in the hot, dusty environments of furnace interiors or adjacent work areas inhaled fibers at concentrations that could be many times greater than modern regulatory limits.

Castable refractory materials — a category used to pour complex shapes that cannot be formed from standard brick — also contained asbestos in many NARCO formulations. Castables are mixed with water and poured or gunned into place, then cured. The mixing process for dry castable materials is particularly hazardous because it generates substantial airborne dust from the dry powder component. Workers who mixed NARCO castables were exposed to asbestos-containing dust at the very beginning of the installation process, before any firing or use occurred.

The service environments for NARCO refractory products also created ongoing exposure hazards beyond the initial installation. As furnace linings aged, operated at extreme temperatures, and were subjected to thermal cycling and mechanical stress, the refractory materials gradually degraded. Cracking, spalling, and erosion of refractory linings was a normal part of furnace operation, and lining maintenance — including patching, partial relining, and eventual full tear-out and replacement — was a recurring event in any industrial facility using NARCO products. Every maintenance and repair cycle was a potential asbestos exposure event for the workers performing the work.

Demolition of old refractory linings was among the most exposure-intensive tasks associated with NARCO products. Workers who broke out old refractory brick and mortar using pneumatic hammers, chisels, and hand tools operated in extremely dusty environments where asbestos fibers from the aged mortar were released in large quantities. Until effective respiratory protection became standard — a transition that occurred only gradually and incompletely during the 1970s and 1980s — demolition workers were fully exposed to the fiber-laden dust generated by this work.

The Honeywell Connection: Why a Technology Giant Funds a Refractory Trust

One of the distinctive features of NARCO's asbestos story is the corporate chain that connects a refractory brick company to one of the world's leading technology and aerospace manufacturers. Honeywell International's financial responsibility for the NARCO Asbestos Trust is the product of a series of corporate mergers and acquisitions spanning several decades — a chain that illustrates how asbestos liability can persist and transfer through corporate transactions long after the original manufacturer has ceased to exist in its original form.

The chain runs as follows: North American Refractories Company, during its corporate history, became part of the Bendix Corporation — a diversified industrial manufacturer best known for its automotive and aerospace components. Bendix acquired NARCO and thereby inherited responsibility for NARCO's products and their associated liabilities. In 1983, Allied Signal acquired Bendix in a high-profile hostile takeover, absorbing Bendix and its subsidiaries — including the inherited NARCO liability — into Allied Signal's corporate structure.

In 1999, Honeywell Inc. and Allied Signal announced a merger, with the combined company taking the Honeywell name. Through this merger, Honeywell inherited Allied Signal's entire liability portfolio, including the chain of responsibility that traced back through Allied Signal's Bendix acquisition to NARCO's refractory products. When NARCO filed for Chapter 11 bankruptcy in 2002, Honeywell — as the successor corporation in the Bendix/Allied Signal acquisition chain — became the primary funder of the bankruptcy trust established to compensate NARCO asbestos claimants.

Honeywell's financial resources are vastly greater than those of the original NARCO entity or even of the Bendix corporation. This has significant practical implications for claimants: the NARCO Trust, backed by Honeywell's financial commitments, is well-funded relative to many other asbestos trusts. The trust's ability to pay mesothelioma claims at 100% of scheduled value — rather than the discounted payment percentages that characterize trusts with more constrained assets — reflects this underlying financial strength.

The Honeywell-NARCO relationship is not without complexity or ongoing litigation. Honeywell has, over the years, disputed various aspects of its liability obligation and negotiated the terms of its trust funding commitments in the context of the bankruptcy proceedings. However, for mesothelioma claimants with qualifying NARCO exposure, the practical outcome has been access to a trust that pays in full for the most serious disease category — an outcome that provides meaningful compensation to individuals and families dealing with one of the most devastating occupational disease diagnoses possible.

Filing a NARCO Trust Claim: Eligibility, Process, and What to Expect

The NARCO Asbestos Trust operates under a Trust Distribution Procedures document that governs every aspect of the claims process. Mesothelioma claimants are entitled to the highest scheduled values and the 100% payment percentage — making a qualified NARCO mesothelioma claim one of the most valuable individual trust claims available in the asbestos compensation landscape. Understanding the requirements for eligibility is essential for any claimant or attorney evaluating whether a NARCO Trust claim is viable.

The medical requirement for a mesothelioma claim is documentation of a confirmed mesothelioma diagnosis. This typically means a pathology report from a tissue biopsy identifying malignant mesothelioma — peritoneal (abdominal cavity), pleural (chest cavity), or pericardial (heart lining). Some trusts accept clinical diagnoses supported by imaging and clinical presentation, but pathological confirmation is the strongest foundation for a mesothelioma claim and is typically required for expedited review processes.

The exposure requirement demands that the claimant demonstrate meaningful, qualifying exposure to NARCO asbestos-containing refractory products. This does not require that the claimant remember specific NARCO product names or model numbers from decades ago. Rather, it requires establishing that the claimant worked in environments where NARCO products were in use — steel mills, glass plants, cement facilities, foundries — and that the nature of their work would have placed them in contact with or in proximity to NARCO refractory bricks, mortars, or castables. Expert witnesses, co-worker affidavits, job site records, and product specification documents from the relevant era can all contribute to establishing the necessary exposure history.

Occupations most likely to have qualifying NARCO exposure include refractory bricklayers and installers who worked directly with NARCO products during furnace construction and relining; steelworkers at mills that used NARCO refractory linings in their blast furnaces and BOF vessels; glass plant workers who maintained and repaired NARCO-lined glass-melting furnaces; cement kiln workers who maintained NARCO rotary kiln linings; and general industrial laborers who worked alongside refractory installation and demolition crews without direct involvement in the refractory work itself.

Once a qualified attorney has assembled the required documentation, the claim is submitted to the NARCO Trust's claims administrator. The administrator reviews the submission, may request additional information, and processes the claim according to the trust's procedures. Upon approval, payment is made at 100% of the applicable scheduled value. The processing timeline can vary, but mesothelioma claims — particularly those supported by strong pathological and exposure documentation — are typically among the higher priority cases given the severity of the disease and the claimant's limited life expectancy at the time of filing.

It is also important to note that NARCO Trust claims can be pursued concurrently with claims against other asbestos trusts and litigation against solvent asbestos defendants. Workers who installed or worked around NARCO refractory products were often also exposed to insulation products from companies like Eagle-Picher, Armstrong World Industries, or Owens Corning. An experienced asbestos attorney will evaluate the full exposure history and identify all available claims across every potentially responsible party.
