PATTEN, Maine — A Georgia corporation’s decision to close the Appalachian Katahdin mill on Mill Street will leave 18 workers unemployed, the company announced Monday.

Shaw Industries Group Inc. of Dalton, Ga., will close the wood veneering mill in the next several weeks. No date has been set, company officials said Monday.

Workers at the mill, located at 19 Mill St., referred comment on the closure to officials at Shaw Industries.

Company officials cited declining market demand, continuously rising transportation costs and the purchase costs for raw material inventories as factors in what they said was a difficult decision to close the facility.

“It is important to note that the closing of the Patten facility does not reflect on the performance of the associates at Plant H2, who have contributed many years of service to Anderson Hardwood and Shaw,” the company said in a press statement.

Shaw Industries Group Inc., a subsidiary of Berkshire Hathaway Inc., is the world’s largest carpet manufacturer and a leading floor covering provider, with more than $4 billion in annual sales and approximately 25,000 associates.

Headquartered in Dalton, Ga., the company manufactures and distributes carpeting, rugs, hardwood, laminate and ceramic tile for residential and commercial applications worldwide.
