LANCASTER, Pa., Sept. 17 /PRNewswire-FirstCall/ -- Armstrong World Industries, Inc. has been awarded U.S. Patent No. 7,261,947 for its NextGen(TM) technology for locking engineered hardwood flooring. Locking hardwood flooring eliminates glue, nails and staples, permitting faster, less expensive installation. NextGen technology provides increased lock strength, resulting in a tighter fit between boards and a more dimensionally stable floor with higher tolerance to moisture, seasonal and climate changes. "In North America today, more than 70-percent of new homes have foundations ideal for a floating, locking hardwood floor," says Dick Quinlan, general manager of Armstrong's Bruce(R) Hardwood Floors business. "Armstrong's NextGen flooring has a structure that can withstand varying moisture levels, allowing it to perform in most construction environments. It is an ideal hardwood floor for new home construction and remodeling projects anywhere in the U.S." NextGen flooring is available in two lines: Armstrong Locking Hardwood(TM), a collection of exotic and domestic hardwoods, and Bruce Turlington(TM) Lock & Fold(R) domestic hardwood flooring.
