Release Details

PORTLAND, Ore., Dec 10, 2003 (BUSINESS WIRE) -- Louisiana-Pacific Corporation (LP) (NYSE:LPX) announced today that it will be taking downtime at five of its North American oriented strand board (OSB) mills for capital projects and routine maintenance. The 41 days of downtime, ranging in duration at each mill, will occur in December and early January. Overall, the downtime will reduce normal production by more than 50 million square feet during the period.

"These capital projects are part of our effort to modernize by installing enhanced technology in our existing mills," said Harold Stanton, vice president of LP's oriented strand board business. "We have committed to a $250 million investment program over a four- to five-year period intended to reduce costs, improve quality and increase capacity."

Stanton continued, "We delayed action on these projects and maintenance activities due to the strong building season. Now that order files have returned to normal levels, we will proceed with the next steps in the program while continuing to service our customers' needs."

The mills involved are located in Sagola, Michigan; Swan Valley, Manitoba; Chambord, Quebec; St. Michel, Quebec; and Carthage, Texas.
