A floor is the bottom surface of a room or vehicle. Floors vary from simple dirt in a cave to many layered surfaces made with modern technology. Floors may be stone, wood, bamboo, metal or any other material that can support the expected load. The levels of a building are often referred to as floors, although sometimes referred to as storeys.
Wood flooring is a popular feature in many houses. Engineered wood flooring consists of two or more layers of wood adhered together to form a plank.

The increased stability of engineered wood is achieved by running each ...
