Lafarge North America Inc. announced investing approximately $120 million to expand the capacity of its state-of-the-art gypsum drywall manufacturing facility in Silver Grove, Ky. The new gypsum wallboard line will increase the annual capacity of the plant from 900 million square feet to 1,600 million square feet. The expanded facility will meet the demands of customers in the north central region of the U.S. and southern Ontario by increasing the supply and the range of products available in these markets. Construction is expected to begin during the first half of 2006 and is scheduled for completion in the second quarter of 2007.

In November 2004, Lafarge also announced that it was investing $75 million to substantially upgrade and double the capacity of its gypsum drywall manufacturing facility in Buchanan, NY. The project is proceeding as planned and expected to be completed in mid-2006.
