Building products manufacturer CertainTeed Corporation announced sales for 2004 of U$D 2.6BN, an increase of around 12% compared to the company's 2003 sales figures. "Overall, 2004 was a great year for CertainTeed," says Peter Dachowski, President and CEO of CertainTeed Corporation. "Despite the rising cost of raw materials, our sales grew more than US$ 250M over the year prior thanks to our strong, broad product offering and stellar workforce." The company opened two new production facilities in 2004, one for the manufacture of windows in West Sacramento, California, and another for the manufacture of insulation in Sherman, Texas. Capacity for premium blowing wool was expanded at the company's insulation plant in Kansas City, Kansas.
