Solid wood flooring come in a wide range of dimensions, styles, and thicknesses, with each plank milled from a single piece of solid timber. Solid wood floors were originally used for structural purposes known as bearers and joists, in most constructions. Modern day construction techniques rarely use solid oak flooring anymore for this reason but more for its appearances and decorative finish. Let’s us not forget wooden floors have been in use for centuries. Many of King Henry’s castles or hunting lodges still have these subfloors in use to date proving oak has been a favorite of even kings and queens.
