Abstract
A wooden flooring strip having a wooden flooring strip, comprising a top surface and a base surface opposed to the top surface, the top surface and the base surface defining between them a predetermined thickness wood flooring material. The predetermined thickness wood flooring material includes a top surface zone adjacent the top surface and a base surface zone adjacent the base surface. The base surface zone has longitudinally-extending wood fibers which have been broken to an extent sufficient to relieve tension on the base surface and thereby increase the flexibility of the flooring strip for more closely adhering to a sub-floor. The top surface zone has longitudinally-extending wood fibers which have been broken to an extent sufficient to relieve tension on the top surface of the flooring strip and to equalize tension on the wood fibers adjacent both the top surface and base surface of the flooring strip.
