Engineered wood flooring is composed of two or more layers of wood in the form of a plank. The top layer is the wood that is visible when the flooring is installed, and is adhered to the core which provides the stability.  It has several benefits over solid wood, beyond dimensional stability and universal use. Patented installation systems (such as "click" or "G6") allows for faster installation, and easy replacement of boards. Engineered wood can use 'floating' installations, further increasing ease of repair and reducing installation times.
