History & Asbestos Use

CertainTeed Corporation, a subsidiary of Saint-Gobain, has been headquartered in the Valley Forge, Pennsylvania area and operated manufacturing facilities producing building materials including asbestos cement pipe (Transite), roofing shingles, and siding products. Transite asbestos cement pipe was one of the most widely installed water and sewer pipe products in the United States, with thousands of miles still in use today. CertainTeed faced extensive asbestos litigation from workers who manufactured and installed its asbestos-containing products and has been a defendant in numerous asbestos personal injury cases.

Exposure Details

Workers at CertainTeed facilities were exposed to asbestos during the mixing of raw asbestos with cement, the forming and curing of pipe and sheet products, and especially during cutting operations on finished products. Cutting Transite pipe and sheet generated heavy clouds of asbestos-laden dust. Plumbers, pipefitters, and construction workers who cut and installed Transite products in the field were also extensively exposed to asbestos fibers throughout their careers.

Workers at Risk

The following job categories at CertainTeed Corporation Valley Forge Plant had the highest risk of asbestos exposure:

  • Pipe production workers
  • Machine operators
  • Mixing operators
  • Cutting operators
  • Maintenance workers

Health Effects

Former CertainTeed manufacturing workers and the vast number of tradespeople who installed Transite and other CertainTeed asbestos products have developed mesothelioma, asbestosis, and lung cancer. Plumbers and utility workers who cut Transite pipe on the job were at particularly high risk. Homeowners who drilled into or cut CertainTeed asbestos siding and roofing during renovations also faced potential exposure.

Health information is based on established medical research on asbestos exposure. Asbestos is classified as a known human carcinogen by the National Cancer Institute, the Agency for Toxic Substances and Disease Registry, and the U.S. Environmental Protection Agency. Consult a physician for medical advice specific to your situation.

Compensation May Be Available

Workers exposed to asbestos at CertainTeed Corporation Valley Forge Plant may be entitled to compensation through asbestos trust funds, personal injury lawsuits, or veterans benefits.
