Louisiana-Pacific Corp was founded in 1973. The Company along with its subsidiaries is engaged in the manufacture of building products. It operates in four segments: North America Oriented Strand Board (OSB); Siding; Engineered Wood Products (EWP); and South America. Its OSB segment manufactures and distributes OSB structural panel products. OSB includes product made from wood strands arranged in layers and bonded with resin. OSB serves many of the same uses as plywood, including roof decking, sidewall sheathing and floor underlayment, but could be produced at a considerably lower cost. The Company's Siding offerings fall into two categories: SmartSide(r) siding products and related accessories; and Canexel siding and accessory products. Its SmartSide(r) products consist of a line of wood-based sidings, trim, soffit and fascia. The Engineered Wood Products segment includes: laminated veneer lumber and laminated strand lumber; I-joists; plywood; and other related products. Its other products category includes the Company's remaining timber and timberlands, and other minor products, services and closed operations. In addition to its U.S. operations, the Company also maintains manufacturing facilities in Canada, Chile and Brazil through foreign subsidiaries and joint ventures. Wood fiber is the main raw material used in many of its operations, and the primary source of wood fiber is timber. The main customers for the Company's building products are retail home centers, manufactured housing producers, distributors and wholesalers in North America and South America, with minor sales to Asia and Europe. The Company competes internationally with several thousand forest and building products firms, ranging from very large, fully integrated firms to smaller enterprises that may manufacture only one or few items.
