• Owens Corning's primary asbestos product was Kaylo calcium silicate insulation containing up to 15% chrysotile asbestos^[6]
• Fibreboard Corporation manufactured asbestos cement building products under the Pabco brand^[6]
• Two claim review options are available: Expedited Review (faster, fixed payment) and Individual Review (higher potential, longer timeline)

What Are the 4 Filing Requirements for the Owens Corning/Fibreboard Trust?

Filing a claim with the Owens Corning/Fibreboard Trust requires meeting 4 specific categories of evidence. Each category must be documented before the trust will process a claim, and incomplete submissions are returned for additional information, which delays the timeline.

The first requirement is a qualifying medical diagnosis. The trust compensates 8 categories of asbestos-related disease, from asbestosis to mesothelioma. A diagnosis must come from a board-certified physician or pathologist and include imaging, pathology reports, or pulmonary function tests as appropriate. Mesothelioma claims receive the highest scheduled values and are eligible for expedited processing.

"The medical evidence requirement is straightforward for mesothelioma cases because the diagnosis itself is sufficient to establish disease severity. The challenge for most claimants is proving product-specific exposure to Owens Corning or Fibreboard materials at identifiable job sites."

— Paul Danziger, Board Certified Personal Injury Trial Lawyer, Danziger & De Llano

The second requirement is documented exposure to Owens Corning or Fibreboard products. This means identifying specific products by name or brand, the location where exposure occurred, and the approximate time period. Common products include Kaylo pipe insulation, Owens Corning fiberglass batts with asbestos additives, and Fibreboard/Pabco building materials.^[6]

The third requirement is proof of identity, including Social Security number verification. For claims filed by surviving family members, death certificates and proof of relationship to the deceased are also required.

The fourth requirement is supporting exposure documentation. This includes employment records showing the claimant worked at a site where the products were present, union membership records, co-worker affidavits confirming product exposure, invoices or purchase orders for the products, or site inspection records. The more supporting evidence provided, the stronger the claim and the higher the potential Individual Review valuation.

How Do Expedited Review and Individual Review Claims Differ?

The trust offers two processing tracks, and choosing the right one significantly affects both the payment amount and timeline. Understanding the asbestos trust fund filing process is essential before selecting a review path.

Expedited Review is a streamlined process that pays a fixed scheduled value based on disease category. Claimants submit the required documentation, and if the claim meets minimum criteria, the trust offers the scheduled value multiplied by the current payment percentage. For mesothelioma, this means a payment of approximately $3,300 to $19,800 at the current 3.3% rate. Processing typically takes 6 to 9 months.

Individual Review allows claimants to present additional evidence of specific damages, including medical expenses, lost income, pain and suffering, and the severity of product exposure. The trust evaluates these factors on a case-by-case basis and may offer compensation above the scheduled value. However, Individual Review takes 12 to 18 months and requires significantly more documentation.

"For mesothelioma claimants with strong exposure evidence and documented economic losses, Individual Review almost always produces a higher payment than Expedited Review. The additional 6 to 12 months of processing time is a worthwhile investment when the potential recovery is significantly greater."

— Paul Danziger, Board Certified Personal Injury Trial Lawyer, Danziger & De Llano

What Products Did Owens Corning and Fibreboard Manufacture with Asbestos?

Owens Corning's most widely distributed asbestos product was Kaylo, a calcium silicate pipe and block insulation that contained up to 15% chrysotile asbestos. Kaylo was used extensively in commercial buildings, industrial facilities, power plants, and military installations from the 1950s through the 1970s. Owens Corning acquired the Kaylo product line from Owens-Illinois in 1958 and continued manufacturing it until the early 1970s.^[6]

Beyond Kaylo, Owens Corning produced fiberglass insulation products that incorporated asbestos as a binding agent, asbestos-reinforced duct insulation for HVAC systems. Various industrial insulation products sold to shipyards, refineries, and manufacturing plants.

Fibreboard Corporation, operating primarily under the Pabco brand, manufactured asbestos cement siding, roofing materials, pipe insulation, and industrial packing materials. Fibreboard's products were common in residential and commercial construction throughout California, the Pacific Northwest, and the southwestern United States.^[6]

"Kaylo insulation was ubiquitous in mid-century American construction. Pipefitters, insulators, electricians, and maintenance workers in thousands of buildings across the country were exposed to this product, often without any warning about its asbestos content."

— Dr. Barry Castleman, Environmental Consultant and Asbestos Industry Historian

What Common Mistakes Delay Owens Corning/Fibreboard Trust Claims?

The most frequent mistake claimants make is submitting incomplete exposure documentation. Simply stating that you worked in a building where Owens Corning products were present is insufficient. The trust requires specific product identification, job site location, approximate dates, and your role at the site. Claims without this specificity are returned for additional documentation, adding 3 to 6 months to the process.

A second common error is selecting Expedited Review without evaluating whether Individual Review would yield substantially higher compensation. For mesothelioma claimants with extensive exposure evidence and significant economic losses, Individual Review can produce payments several times higher than the fixed Expedited schedule. An attorney experienced with asbestos trust claims can analyze your specific case and recommend the optimal review track.

Third, many claimants file with only one or two trusts when they may be eligible for 10 or more. Each building where asbestos exposure occurred may have contained products from multiple manufacturers, each with its own trust. Failing to identify all applicable trusts leaves substantial compensation on the table. The U.S. Senate Judiciary Committee has noted that the trust system now involves over 60 active trusts with distinct filing procedures.

How Does the Owens Corning/Fibreboard Trust Fit into a Broader Compensation Strategy?

The Owens Corning/Fibreboard Trust is one component of a comprehensive compensation strategy for asbestos victims. Because most workers were exposed to products from multiple manufacturers, an experienced mesothelioma attorney will identify all applicable asbestos trust funds and coordinate filings across them.

Trust fund claims can be pursued alongside personal injury lawsuits against solvent defendants, workers' compensation benefits, and VA disability benefits for veterans. Each compensation source operates independently, and receiving payment from one does not disqualify claims to others.

The RAND Corporation estimated that total asbestos litigation costs exceeded $70 billion through 2005, with trusts paying a growing share as more manufacturers entered bankruptcy. Today, the trust system processes the majority of asbestos claims in the United States.^[9]

Workers who were exposed to Kaylo insulation, Fibreboard/Pabco building products, or other Owens Corning asbestos materials should consult with an attorney promptly. While the trust does not have a fixed filing deadline, state statutes of limitations apply, and trust payment percentages may decrease as assets are distributed.
