Johns Manville is an American company based in Denver, Colorado, that manufactures insulation, roofing materials and engineered products. For much of the 20th century, the then-titled Johns-Manville Corporation was the global leader in the manufacture of asbestos-containing products, including asbestos pipe insulation, asbestos shingles, asbestos roofing materials and asbestos cement pipe. The stock of Johns-Manville Corporation had been included in the Dow Jones Industrial Average from January 29, 1930 to August 27, 1982, when it was replaced by American Express. In 1981, Johns-Manville Corporation was renamed simply Manville. In 1982, facing unprecedented liability for asbestos injury claims, the company voluntarily filed for bankruptcy under Chapter 11 of the U.S. Bankruptcy Code. More information...
