USG Corporation

ABOUT THIS COMPANY:

As the number one Sheetrock manufacturer in the world, USG has built a strong reputation in the building industry. Divided into three main operations, North American Gypsum, Worldwide Ceilings, and Building Products Distribution, USG does more than just make the building blocks of houses, skyscrapers, and landmarks. It makes gypsum, ready-mixed joint compounds, abuse-resistant wall panels, poured gypsum underlayments, construction plaster products, fiberglass-reinforced cement board, ceiling suspension grids, and ceiling tiles for both residential and commercial clients. Started in 1902 with the emergence of 30 regional gypsum manufacturing companies, the United States Gypsum Company began building and manufacturing products. From its first product, Pyrobar, to the phenomenon that is Sheetrock, USG's reputation stands tall in a foundation built by a century of hard work. Warren Buffett, the billionaire chairman of Berkshire Hathaway, owns 15 percent of the company.
