Includes decking and railing made at LP’s Meridian, Idaho plant and sold as WeatherBest®, Veranda® and ABTCo after Jan. 1, 2005

NASHVILLE, Tenn. (August 7, 2008) — Louisiana-Pacific Corporation (LP Building Products) (LP) (NYSE: LPX) today issued a product advisory for composite decking materials purchased after January 1, 2005, and made by LP at its Meridian, Idaho facility.

Some of the product can prematurely deteriorate and break, posing a risk of injury to consumers. LP decking products, including deck board and railings sold under the names of LP WeatherBest®, WeatherBest®, ABTCo and Veranda® are subject to this advisory.

The products are used for building outdoor decks. LP has received claims of premature deterioration of a small portion of its decking product due to variations in manufacturing processes in this time frame.

LP Executive Vice President of Specialty Products and Sales Rick Olszewski said, “We want consumers to be aware of the potential risk of injury, and to contact us. Though only a small portion of decking sold has been affected by these issues, we urge people who bought or installed these composite decking products after January 1, 2005 to contact us for an inspection through our decking notice Web site or customer service line.”

 Lafarge’s Buchanan Plant To Produce Environmentally-Friendly product
Lafarge, North America’s largest diversified supplier of construction materials, and Mirant Corporation, a leading U.S.-based competitive energy company, today announced that they have signed a long-term agreement under which Mirant, beginning in 2010, will supply synthetic gypsum to Lafarge’s gypsum drywall manufacturing facility in Buchanan, New York.  
Reflecting Lafarge’s long-standing commitment to producing “green” products, the company will invest in an upgrade of its Buchanan plant which will enable it to manufacture a full line of gypsum products using this environmentally-friendly material. The supply agreement will also ensure Lafarge’s continuing, cost-effective access to a critical raw material used in its building products. Upon scheduled completion in 2010, the gypsum board manufactured in this plant will exceed 99 percent recycled content by weight and qualify toward the attainment of LEED^® credits in the construction of “Green Buildings” throughout the northeastern United States.
Lafarge is an industry leader in the use of synthetic gypsum. With the addition of the Buchanan plant, nearly all of the gypsum board manufactured by Lafarge in North America will be made with 100 percent recycled paper and recycled gypsum. Currently, Lafarge’s Silver Grove, Kentucky plant and Palatka, Florida plant qualify for this distinction.
“This is a major step in our evolution to be the industry leader in gypsum board and the number one supplier of ‘green’ building products,” said Ike Preston, President of Lafarge Gypsum in North America. “This upgrade will allow us to serve virtually all of our trading area with recycled product and assist our customers in meeting the requirements of LEED^® certified construction.”
Mirant will transport the synthetic gypsum to Lafarge’s Buchanan facility from its Morgantown and Chalk Point electric generating stations in Maryland.  Synthetic gypsum is a by-product created from the sulfur dioxide removal technology currently being constructed at Mirant’s Maryland power plants as part of the company’s $1.6 billion investment in air pollution control technologies.     
“Partnering with Lafarge allows Mirant to maximize the environmental benefit from the installation of these systems.  The beneficial use of the synthetic gypsum eliminates the need for waste disposal of the by-product,” said Bob Driscoll, CEO, Mirant Mid-Atlantic, LLC.
