Lumber, plywood prices skyrocket By BERNARD SIMON, New York Times
Almost three-fifths of all structural wood panels now sold are oriented-strand board, or OSB, compared with a quarter in the early 1990s.
Prices of both OSB and plywood reached records one week last month. According to Random Lengths, a trade publication, 1,000 square feet of -inch OSB sells for $503 in the north-central United States; this time last year, the same amount cost $170. Half-inch four-ply southern pine plywood is up to $523 for 1,000 square feet, from $240 a year ago.
