Abstract
Methods and articles of manufacture relating to engineered hardwood flooring are provided. Engineered hardwood flooring is produced by drying a structural layer comprising a hardwood to a moisture content from about 0.1% to about 3%, whereupon a cell structure of the hardwood collapses. The dried structural layer is humidified to where the hardwood has an increased moisture content greater than about 3%. First and second outer layers are adhered to respective first and second sides of the structural layer to form an engineered product, the structural layer sandwiched by the first outer layer and the second outer layer.
