Wood – Solid Wood or Engineered
Solid wood flooring is made of solid wood throughout and is usually made of a hardwood species, such as oak, maple, or walnut. One major advantage is over the course of its lifespan, it can be sanded and refinished several times.
Engineered wood flooring, while it looks very similar on the surface, it is made from a thin layer of hardwood bonded over a substrate of high-quality plywood. This make it less expensive than solid hardwood, engineered flooring can only be sanded and refinished only once since the surface hardwood layer is rather thin.
