FOR RELEASE AT 8:00 A.M. (EDT) WEDNESDAY, JULY 27, 2005

LP Reports Second Quarter Profits

Nashville, TN. (July 27, 2005) - Louisiana-Pacific Corporation (LP) (NYSE: LPX) reported today second quarter net income of $100 million, or $0.90 per diluted share, on sales from continuing operations of $692 million.  In the second quarter of 2004, LP’s net income was $192 million, or $1.77 per diluted share, on sales from continuing operations of $790 million. For the first six months of 2005, LP reported net income of $202 million, or $1.82 per diluted share, on sales from continuing operations of $1.4 billion compared to net income of $299 million, or $2.73 per diluted share, on sales from continuing operations of $1.5 billion for the first six months of 2004.

For the second quarter of 2005, income from continuing operations was $104 million, or $0.94 per diluted share. In the second quarter of 2004, LP’s income from continuing operations was $188 million, or $1.71 per diluted share.  For the first six months 2005, income from continuing operations was $210 million, or $1.89 per diluted share. For the first six months of 2004, income from continuing operations was $298 million, or $2.72 per diluted share. Results for the first six months of 2004 included charges primarily for the early extinguishment of debt, impairments of long-lived assets, litigation and other net operating charges totaling $63 million ($39 million after tax, or $0.36 per diluted share).

“Though OSB prices continued a downward trend in the quarter, our other businesses showed improved performance from last quarter, with the result that LP again earned over $100 million in quarterly net income,” said Rick Frost, CEO.  “Compared to the same quarter last year, when the industry realized record OSB pricing, OSB prices declined 27%,  leading to an almost $150 million year-over-year decline in both quarterly OSB sales and operating profits. Our non-OSB businesses grew sales by over $35 million compared to same quarter last year. ”

Frost continued, “Engineered Wood Products experienced strong profitability compared to the previous quarter, due to both increased sales and volumes.  Siding rebounded from a slow first quarter, and our decking business performed strongly.  We are making steady progress toward our goal of growing the sales and profitability of our non-OSB businesses, while still enjoying a favorable OSB market.”

At 11:00 a.m. EST (8:00 a.m. PST) today, LP will host a webcast on its second quarter 2005 financial results.  To access the live webcast and accompanying presentation, visit www.lpcorp.com and go to the “Investor Relations” section from the main menu.

Accounting standards require that the estimated effective income tax rate (based upon estimated annual amounts of taxable income and expense) by income component for the year be applied to year-to-date income or loss at the end of each quarter. At year end, the income tax accrual is adjusted to actual with the difference between the previously accrued year to date balance and actual being charged to the current quarter.  The primary difference between the blended rate (39%) on continuing operations and the calculated rate relates to a permanent difference associated with certain inter-company debt which is denominated in Canadian dollars. The components and associated effective income tax rates applied to each period are as follows:
