Insuline Refractory Cement (Quigley Co., Inc.)

Insuline Refractory Cement is a high-temperature insulating and sealing product manufactured by Quigley Co., Inc., a New York-based specialty refractory manufacturer with a long history of supplying industrial facilities across the United States. Like many refractory and insulating products of its era, Insuline Refractory Cement has been the subject of asbestos-related litigation, with plaintiffs alleging that the product contained asbestos fibers and that exposure caused serious and life-threatening illnesses. This reference article documents what is known about the product, how workers may have come into contact with it, and what legal options remain available for those who were exposed.

Product Description

Insuline Refractory Cement was marketed and sold by Quigley Co., Inc. as a specialty cement designed for use in high-temperature industrial environments. Quigley produced a broad line of refractory products intended for use in foundries, steel mills, power plants, refineries, and other heavy industrial settings where equipment and piping systems were routinely subjected to extreme heat. Refractory cements of this type were engineered to bond, seal, and insulate surfaces that standard construction materials could not withstand.

The product fell into two overlapping categories: pipe insulation and refractory materials. In the pipe insulation context, products like Insuline Refractory Cement were applied to high-temperature pipes, boilers, and related equipment to reduce heat loss and protect surrounding structures. In the refractory context, such cements were used to line furnaces, kilns, incinerators, and similar industrial apparatus. Quigley Co., Inc. operated during decades when asbestos was a standard additive in refractory and insulating formulations, valued for its heat resistance, binding properties, and low cost.

The precise years during which Insuline Refractory Cement was produced and sold have not been independently confirmed in publicly available regulatory filings for purposes of this article. However, Quigley’s broader product line was distributed throughout much of the twentieth century, and litigation records associate the company’s refractory products with industrial worksites active from roughly the mid-twentieth century through the period when asbestos use began to be phased out following increased regulatory scrutiny in the 1970s and 1980s.

Asbestos Content

Plaintiffs in asbestos litigation have alleged that Insuline Refractory Cement manufactured by Quigley Co., Inc. contained asbestos as a component of its formulation. Refractory cements of this class commonly incorporated asbestos fibers — most frequently chrysotile, though amphibole varieties were also used in industrial products of this period — because asbestos provided thermal stability, tensile reinforcement, and resistance to cracking under repeated heating and cooling cycles.

Litigation records document claims asserting that Quigley’s refractory and insulating cement products were composed of materials that, when disturbed during normal use, generated respirable asbestos fibers. The specific asbestos content by percentage for Insuline Refractory Cement has not been confirmed in available public regulatory documentation for this article. Plaintiffs alleged that the product’s composition was not adequately disclosed to end users or the workers who handled it, leaving those individuals unaware of the risks associated with their exposure.

It is well established under OSHA standards and the findings underlying AHERA that no safe level of asbestos exposure has been identified, and that even intermittent exposure to respirable asbestos fibers carries a risk of causing mesothelioma, asbestosis, lung cancer, and other asbestos-related diseases. These diseases typically have latency periods of ten to fifty years, meaning workers exposed decades ago may only now be receiving diagnoses.

How Workers Were Exposed

Industrial workers represent the primary population identified in connection with potential exposure to Insuline Refractory Cement. The nature of the product — a cement applied to pipes, boilers, furnaces, kilns, and related high-temperature equipment — meant that it was handled across a wide range of industrial trades and settings.

Litigation records document exposure scenarios involving workers in steel mills, oil refineries, chemical plants, power generating stations, and heavy manufacturing facilities. In these environments, refractory cement products were mixed, applied, troweled, and finished by hand. When dry product was mixed with water or when hardened cement was cut, chipped, or removed during maintenance and repair, clouds of dust were generated. Plaintiffs alleged that this dust contained respirable asbestos fibers that were inhaled by workers in the immediate vicinity as well as by bystanders working in adjacent areas.

Specific trades that may have encountered Insuline Refractory Cement in the course of normal duties include, but may not be limited to:

• Industrial maintenance workers who repaired and replaced refractory linings in furnaces, kilns, and boilers
• Pipefitters and insulators who applied or removed pipe insulation cements in industrial facilities
• Millwrights and equipment operators working in close proximity to areas where refractory cement was being applied or disturbed
• General laborers assigned to mix, carry, or clean up refractory cement materials on industrial job sites

Plaintiffs alleged that ventilation in many of these industrial settings was inadequate, that respiratory protective equipment was either not provided or not required by employers, and that workers had no reasonable way of knowing that the cement they were handling contained hazardous asbestos fibers. Litigation records further document claims that Quigley Co., Inc. was aware or should have been aware of the hazards associated with asbestos-containing refractory products and failed to adequately warn those who would foreseeably be exposed.

Documented Trust Fund / Legal Options

Quigley Co., Inc. filed for bankruptcy protection under Chapter 11 of the United States Bankruptcy Code in 2004, in significant part due to the volume of asbestos personal injury claims filed against the company arising from its refractory product lines. As of the time this article was prepared, Quigley’s bankruptcy reorganization proceedings had a prolonged and complex history in the federal courts, and the establishment of a fully operational, Congressionally recognized Section 524(g) asbestos trust had not been confirmed through publicly available documentation in the same manner as trusts associated with other major asbestos defendants.

Individuals who believe they were exposed to Insuline Refractory Cement or other Quigley refractory products should consult with a qualified asbestos litigation attorney to determine the current status of any Quigley-related trust or bankruptcy settlement mechanism and to evaluate available legal options. Because asbestos litigation involving Quigley products has proceeded through the tort system as well as bankruptcy proceedings, attorneys experienced in asbestos personal injury matters are best positioned to advise on the most current and appropriate avenue for pursuing a claim.

Potential claimants should gather and preserve the following types of documentation, which are relevant to any asbestos exposure claim:

• Employment records, union records, or other documentation establishing work history at relevant facilities
• Medical records confirming a diagnosis of mesothelioma, asbestosis, lung cancer, or another asbestos-related condition
• Witness statements or coworker testimony regarding the use of Quigley products at specific job sites
• Any product literature, purchase orders, or safety data records referencing Insuline Refractory Cement

Statutes of limitations apply to asbestos claims and vary by state, typically running from the date of diagnosis or the date on which the claimant reasonably should have connected their illness to asbestos exposure. Individuals and family members of deceased workers are encouraged to seek legal counsel promptly to protect their rights.
