Abstract
A wood flooring product for assembly into a wood floor is disclosed. The flooring product includes a top, decorative layer, an intermediate layer bonded to the top layer, and a base layer bonded to the intermediate layer. The top, intermediate and base layers are bonded in registration to define a laminated elongate wood flooring strip. A tongue and a groove are formed on respective side edges of the flooring strip. The tongue and groove extend along the length of the flooring strip, and lock adjacent flooring strips together side-to-side to form an assembled wood floor. The base layer has a multiplicity of closely spaced-apart scores cut transverse to the length of the flooring strip along substantially the entire length of the flooring strip. The scores relieve stress and increase flexibility in the wood strip for more closely adhering to irregularities of a sub-floor.
