December 12, 2007

World’s First and Only Such Product to Earn EPP Status GRAND RAPIDS, Mich.--(BUSINESS WIRE)--Universal Forest Products, Inc. (Nasdaq:UFPI), the nation’s leading manufacturer and distributor of treated wood products, is proud to note that the chemical formulation it uses to treat wood is the only one to earn the esteemed Green Cross recognition, which marks its treated wood as an Environmentally Preferred Product. Universal’s treated product line, ProWood Micro®, is manufactured with MicroPro™, a product of Osmose Inc. that last week was named the first and only wood preservative technology in the world to earn the Environmentally Preferable Product (EPP) certification from Scientific Certification Systems, a leading third-party certification firm. To earn EPP certification, a product must demonstrate reduced impact on human health and the environment when compared to other products that serve the same purpose as measured by guidelines published by the U.S. Environmental Protection Agency. “We have touted the environmental benefits of treated wood for decades,” said Universal President and CEO Michael B. Glenn. “We’re delighted that our ProWood Micro products now can be recognized as friendly to the environment and human health, thanks to the state-of-the-art micronizing technology developed by our good partners at Osmose.” “Our business depends on a healthy environment, which our practices have recognized and promoted for years and years,” Glenn added, noting that Universal’s pressure-treated lumber products are produced from plentiful, fast-growing species from managed forests. In addition, use of pressure-treated wood, which lasts decades, saves millions of trees each year.
