CertainTeed Corporation Asbestos Exposure: Products, Workers & Claims
CertainTeed Corporation manufactured and sold asbestos-containing construction products, including asbestos-cement pipe, asphalt roofing materials, certain gypsum products and specialty railroad insulation. Workers who cut, installed, repaired or removed these products may have encountered airborne asbestos fibers. The product, dates and actual work conditions must be established for each individual.
CertainTeed’s asbestos liabilities became part of DBMP LLC following a 2019 corporate restructuring, and DBMP filed for Chapter 11 bankruptcy in January 2020. The resulting legal process is different from filing with an established asbestos settlement trust. This guide explains documented products, exposure pathways, claims evidence and the bankruptcy context without inventing trust funding or payment figures.
🏢 CertainTeed Corporation: Company History & Timeline
CertainTeed is a building-products manufacturer with roots dating to 1904. Historical court records distinguish the company that manufactured or sold asbestos-containing products (often described as Old CertainTeed) from entities created in its later corporate restructuring. Its ultimate corporate parent is Saint-Gobain. The corporate distinctions matter because the appropriate claims process may involve DBMP’s bankruptcy rather than an ordinary claim against an operating manufacturer.
CertainTeed Company Facts
| Company detail | Documented information |
|---|---|
| Origins | 1904; historical predecessor General Roofing Manufacturing Company |
| Industry | Building products, including roofing, pipe and gypsum materials |

Federal court records describe asbestos claims associated with CertainTeed products dating back decades. A 2026 Fourth Circuit decision discusses the bankruptcy’s effect on lawsuits and confirms that the DBMP proceedings remained central to the claims dispute at the time of that decision. Do not confuse the company’s continued commercial operations with the status of DBMP’s bankruptcy case.

🧱 CertainTeed Asbestos Products & Historical Product Dates
A federal bankruptcy court decision identifies asbestos-cement pipe, asphalt roofing products, other asbestos-cement products, certain gypsum products and specialty railroad insulation among products Old CertainTeed manufactured or sold between the 1930s and 1993. These are historical categories: not every CertainTeed product, current product or item within a category contained asbestos.
Asbestos Product Identification Table
| Product category | Documented historical context | Evidence to identify an individual product |
|---|---|---|
| Asbestos-cement pipe | Manufactured into the early 1990s; a bankruptcy filing states sales continued as late as 1993 | Pipe markings, specifications, utility records, plant records, invoices |
| Asphalt roofing materials | Included in the court’s historical asbestos-product categories | Roofing plans, product labels, purchase records, original catalogs |
| Other asbestos-cement products | Identified in federal bankruptcy findings; specific formulations and dates vary | Product specifications, manufacturing records, testing |
| Certain gypsum products | Identified in court records; do not assume all drywall or joint compound contained asbestos | Exact product name, formulation, installation date, invoices |
| Specialty railroad insulation | Identified in bankruptcy court findings | Railroad equipment and procurement records, product identification |
Chronological Product Table
| Period | What the records establish |
|---|---|
| 1930s | Beginning of the broad historical period of CertainTeed asbestos-containing product manufacture or sales cited in court records |
| 1965–early 1990s | A federal appellate record describes asbestos-cement pipe manufacture at the Riverside, California plant during this period |
| 1992–1993 | A bankruptcy filing describes asbestos-cement pipe production as late as 1992 and sales as late as 1993 |
| After installation | Previously installed asbestos-containing products may remain in buildings or infrastructure; their presence requires site-specific confirmation |
Product-specific dates commonly reproduced on other websites are not substituted for original manufacturer records here. A contemporaneous catalog, purchase order or engineering specification can narrow the exposure window. See asbestos exposure in products for further identification guidance.
⚠️ How CertainTeed Asbestos Exposure Could Occur
Asbestos fibers can become airborne when asbestos-containing products are cut, drilled, sanded, sawed, broken or removed. Historical asbestos-cement pipe work may have involved sawing, beveling, drilling and fitting pipe. Roofing and gypsum work may have involved installation, scraping, repair and demolition, depending on the specific asbestos-containing product.
Exposure Activity Table
| Activity | Potential exposure mechanism | Useful evidence |
|---|---|---|
| Pipe cutting and beveling | Dust from asbestos-cement pipe | Pipe manufacturer, saw records, job logs, witnesses |
| Roofing repair and removal | Disturbance of confirmed asbestos-containing roofing products | Roof specifications, invoices, material testing |
| Gypsum product work | Dust from an identified asbestos-containing formulation | Product packaging, dates, application records |
| Manufacturing and tool maintenance | Handling product dust or contaminated cutting equipment | Plant assignment, maintenance logs, coworker accounts |
| Demolition | Disturbance of historical installed material | Building surveys, demolition plans, samples |
Exposure cannot be inferred solely from the CertainTeed name, a job title or an old building. Investigators should establish the exact material, asbestos content, work task, proximity, duration and conditions. Take-home exposure is a separate question requiring evidence that asbestos-contaminated dust was carried into a household.
👷 Workers, Job Sites, Government Buildings & Military Use
Workers who may need to investigate CertainTeed product exposure include pipe installers, utility crews, construction workers, roofers, drywall finishers, maintenance workers, demolition crews, manufacturing personnel and people servicing cutting equipment. These are possible pathways, not a confirmed count of exposed people.
Employee and On-Site Worker Exposure Table
| Worker group | Potential work | Verified exposed population |
|---|---|---|
| Factory and pipe-production employees | Manufacture and processing of identified asbestos-containing products | No defensible company-wide count established |
| Cutting-tool maintenance workers | Handling dust on saw blades and equipment | No defensible count established |
| Warehouse and transport workers | Handling documented materials under dust-generating conditions | No defensible count established |
Non-Employee Product Exposure Table
| Group | Potential work or contact | Verified exposed population |
|---|---|---|
| Pipe installers and utility workers | Cutting and installing asbestos-cement pipe | Not established |
| Roofers and renovation crews | Disturbing confirmed asbestos-containing roofing materials | Not established |
| Drywall and building trades | Working with specific asbestos-containing gypsum products | Not established |
| Demolition and maintenance personnel | Disturbing installed products | Not established |
| Household members | Potential take-home dust transfer, if supported by evidence | Not established |
🪖 Military and Government Facilities
Asbestos-cement pipe and other historical construction materials could be encountered in municipal utilities, government infrastructure or military construction, but the records used here do not prove CertainTeed products were installed at any named military base, barracks, VA hospital or government building. Verify facility-specific use through procurement documents, utility maps, construction specifications, invoices or asbestos surveys before naming a location.

⚕️ Asbestos-Related Health Risks
Inhaled asbestos fibers can cause mesothelioma, asbestos-related lung cancer and nonmalignant diseases such as asbestosis. Disease may develop decades after exposure. A diagnosis alone cannot identify CertainTeed as the source of an individual’s exposure or establish legal liability.
Tell a qualified clinician about historical job duties, products, exposure dates and symptoms. Medical evaluation and any screening decisions should be individualized. Smoking and asbestos exposure can jointly increase lung-cancer risk.
Medical Evidence Table
| Evidence | Purpose |
|---|---|
| Pathology and diagnosis records | Document the condition and diagnosis date |
| Imaging and specialist reports | Support clinical evaluation |
| Occupational history | Identify possible exposure sources and timing |
| Product and work records | Connect a particular material and task to the history |
💰 CertainTeed Asbestos Claims: DBMP Bankruptcy and Trust Status
Following a 2019 restructuring, DBMP LLC assumed certain historical CertainTeed asbestos liabilities and filed Chapter 11 in January 2020. Court documents discuss a proposed process to resolve present and future claims through a potential asbestos trust under Bankruptcy Code section 524(g). A proposed trust is not the same as an established, funded trust accepting claims.
A February 11, 2026 Fourth Circuit opinion affirmed a decision declining to lift the bankruptcy automatic stay for certain claimants. That ruling addressed stay relief; it did not establish an operating CertainTeed asbestos trust, a universal claim value or a guaranteed payment. Bankruptcy status and any subsequent plan confirmation should be checked against the current DBMP court docket before publication or filing.
Bankruptcy and Trust Facts
| Item | Documented status |
|---|---|
| Historical liability entity | DBMP LLC following the 2019 restructuring |
| Chapter 11 filing | January 2020 |
| Potential trust | A section 524(g) trust was contemplated in bankruptcy proceedings; do not represent it as an operating trust without a confirmed effective plan |
| Trust establishment date | Not verified as established |
| Initial trust funding | Not verified |
| Payment percentage | Not verified; no Celotex payment percentage applies |
| Scheduled mesothelioma or lung-cancer values | Not verified as operative trust values |
| Official claims information | DBMP bankruptcy court filings and authorized claims administrator; verify current procedures |
Do not use a purported “CertainTeed asbestos trust” website or published payout estimate without confirming its legal status against the bankruptcy court’s operative orders. A claimant’s options may depend on the automatic stay, claim classification, court orders and applicable law. See how asbestos trusts work for general context; this does not establish an active CertainTeed trust.
📋 CertainTeed Claim Evidence & Historical Statistics
Relevant evidence includes a confirmed diagnosis, dates and locations of work, product names, pipe markings, invoices, engineering specifications, coworker accounts, photographs and records describing dust-generating tasks. Preserve original documents and review the bankruptcy docket for the current filing process and any applicable deadlines.
Historical Litigation and Exposure Statistics
| Measure | What reliable records say | Important limitation |
|---|---|---|
| Asbestos-related litigation | A 2026 federal appellate opinion describes hundreds of thousands of asbestos-related tort claims historically asserted against CertainTeed | Not a count of distinct people exposed or current pending claims |
| Annual claim resolution spending | The appellate opinion states less than $10 million annually in the 1990s and an average of approximately $80 million annually since 2002 | Historical spending figures, not trust assets or individual settlements |
| Direct employee exposure estimate | No verified company-wide total identified | Do not invent a number |
| Non-employee product exposure estimate | No verified company-wide total identified | Do not invent a number |
| Trust claims paid or dollars distributed | No operative CertainTeed trust total verified | Do not substitute Celotex statistics |
Historical asbestos litigation statistics cannot be used to calculate the number of workers exposed. An individual claim requires product-specific exposure evidence and legal review. See mesothelioma lawsuit information for broader claims context.
❓ Frequently Asked Questions
Did CertainTeed manufacture asbestos-containing products?
Yes. Federal court records identify asbestos-cement pipe, asphalt roofing products, other asbestos-cement materials, certain gypsum products and specialty railroad insulation.
When did CertainTeed stop selling asbestos-cement pipe?
A bankruptcy filing states the company manufactured asbestos-cement pipe as late as 1992 and sold it as late as 1993. Dates for other products require separate verification.
Did all CertainTeed products contain asbestos?
No. Product identification and formulation must be established for the relevant time period; the company’s name alone is not evidence of asbestos content.

Potentially pipe installers, utility crews, roofers, construction trades, manufacturing employees and maintenance workers performing tasks involving confirmed asbestos-containing products. Individual exposure requires evidence.
Were CertainTeed materials used on military bases?
The sources reviewed do not establish CertainTeed product use at specific military facilities. Site-specific purchasing, construction or asbestos survey records are needed.
Is there an established CertainTeed asbestos settlement trust?
DBMP bankruptcy documents discuss a potential trust, but an established, operating trust and its current payment terms have not been verified here. Confirm the latest court orders before relying on any trust claim instructions.
How much does a CertainTeed asbestos claim pay?
No universal payout applies. This article does not publish an unverified trust payment percentage, scheduled value or guaranteed settlement.
What should someone do after a diagnosis and suspected exposure?
Seek appropriate medical care, preserve employment and product records, and obtain individualized legal guidance about the DBMP bankruptcy, court orders and deadlines. Compensation is not guaranteed.
