CertainTeed

CertainTeed is a North American manufacturer of building materials for both commercial and residential construction and is a wholly owned subsidiary of Saint-Gobain SA, based in Paris.

As a result, CertainTeed is now a major defendant in product liability lawsuits brought by persons who worked on water utility projects and their families.

On April 29, 2010, in a product liability case filed by a mesothelioma patient whose husband used to cut CertainTeed pipe for a living, a Los Angeles Superior Court jury returned a verdict of $8.8 million in compensatory damages and $200 million in punitive damages against CertainTeed and the Los Angeles Department of Water and Power.

A class action suit brought by representatives of the end users against CertainTeed Organic Shingles was approved on September 1, 2010.
