Ruberoid Air Cell

Product Description

Ruberoid Air Cell was an insulation product manufactured under the Ruberoid brand, which operated for decades as one of the most recognized names in American building and industrial materials. G-I Holdings, the corporate entity that succeeded General Building Products and held the Ruberoid product lines, was responsible for manufacturing and distributing Ruberoid-branded materials across a wide range of commercial, industrial, and construction applications.

The Ruberoid name became synonymous with a broad catalog of construction and insulation products, and Air Cell represented one entry in that catalog designed to address thermal insulation needs in industrial and commercial settings. Air Cell insulation products of this era were commonly applied in environments where heat retention and pipe or equipment protection were primary concerns, including industrial facilities, manufacturing plants, and large-scale building systems. The product’s name references the cellular or void-based structure typical of certain insulation formats designed to trap air and reduce heat transfer across surfaces.

G-I Holdings, as the successor entity holding liability for Ruberoid-branded products, has been the subject of extensive asbestos-related litigation. The company’s corporate history is closely connected to the broader legacy of the Ruberoid Company and its acquisition into larger building materials conglomerates during the mid-to-late twentieth century — a period when asbestos use in industrial insulation and related products was widespread across American industry.

Asbestos Content

Litigation records document that Ruberoid-branded insulation products from the mid-twentieth century were alleged to have contained asbestos as a functional component of their composition. Plaintiffs alleged that asbestos-containing materials were incorporated into Ruberoid product lines to enhance thermal resistance, structural integrity, and fire-retardant properties — characteristics that made asbestos a commercially attractive additive in insulation, roofing, pipe covering, and related building materials manufactured during this period.

The specific formulation of Ruberoid Air Cell, including the type and percentage of asbestos fiber used, has been addressed in litigation proceedings. Plaintiffs alleged that the product, consistent with other Ruberoid-branded insulation materials of its era, relied on asbestos-containing mineral components that could release respirable fibers when the product was cut, abraded, handled, or otherwise disturbed during installation or maintenance activities.

Asbestos fibers — including chrysotile, amosite, and crocidolite varieties — were used broadly across industrial insulation products during the decades when Ruberoid Air Cell was produced. The health hazards associated with inhaling these fibers, including mesothelioma, asbestosis, and lung cancer, have been extensively documented by regulatory bodies including OSHA and the EPA, and form the scientific foundation of litigation involving products like Ruberoid Air Cell.

How Workers Were Exposed

Industrial workers represent the primary occupational group identified in litigation involving Ruberoid Air Cell. Because this product was used in industrial settings — including facilities housing boilers, pipe systems, and mechanical infrastructure — the workers most likely to encounter the product on a regular basis were those involved in the installation, maintenance, repair, or removal of insulation systems.

Litigation records document that workers in industrial environments were exposed to Ruberoid Air Cell during routine handling of the material. Plaintiffs alleged that cutting insulation sections to fit pipe dimensions, pressing or shaping the material around equipment, and removing old or damaged insulation all created conditions under which asbestos fibers could become airborne. Once airborne, these microscopic fibers could be inhaled by workers in the immediate vicinity and by bystanders working in adjacent areas of the same facility.

The nature of industrial work environments amplified exposure risks. Boiler rooms, mechanical spaces, and pipe chases — common locations for air cell insulation — were frequently enclosed or poorly ventilated, allowing airborne fibers to concentrate rather than dissipate. Workers in these environments often spent extended periods performing repetitive tasks that repeatedly disturbed insulation materials, accumulating exposure over the course of careers that could span decades.

Beyond direct installers, litigation records document that other trades working alongside insulators — including pipefitters, boilermakers, and general laborers — were alleged to have experienced secondary or bystander exposure when Ruberoid Air Cell and similar products were being handled nearby. The cumulative nature of asbestos-related disease means that even intermittent exposure over a long working life could contribute to the development of serious illness years or decades after the original contact occurred.

The latency period for asbestos-related diseases — which can range from ten to fifty years between exposure and diagnosis — means that workers exposed to Ruberoid Air Cell during peak industrial production decades may be receiving diagnoses today.
