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.[1]
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.[1]
Berkshire Hathaway bought the company in 2001, then chairman and CEO Jerry Henry retired in 2004. At that point, Steve Hochhauser became chairman, president and CEO. Todd Raba succeeded him in the summer of 2007; he came from MidAmerican Energy Holdings, another Berkshire Hathaway company. In November 2012, Mary Rhinehart was named president and CEO,[2] and she added the title of chairman in 2014. In September 2020, Bob Wamboldt became CEO and president, while Rhinehart remained as chairman.
Today, Johns Manville is a manufacturer and marketer of products for building insulation, mechanical insulation, commercial roofing and roof insulation, as well as fibers and non-woven materials for commercial, industrial and residential applications. The company serves markets that include aerospace, automotive and transportation, air handling, appliance, HVAC, pipe and equipment, filtration, waterproofing, building, flooring, interiors and wind energy. Johns Manville has annual sales over $4.5 billion. The company employs 8,000 people and operates 46 manufacturing facilities in North America and Europe.
