The beauty of wood
The boards, or planks, are sold either unfinished or prefinished. Unfinished wood floors require sanding and varnishing after installation, while prefinished planks are sanded and varnished at the factory, which eliminates the need to do this at home.
Two other types of product are available in the wood flooring category: engineered wood and laminate. Engineered wood looks very much like solid wood flooring. The planks are composed of two to five laminated layers of derivative wood products that are cross-layered and bonded together. The top layer is made from North American or exotic hardwood species.
Laminate flooring is made from several layers of synthetic materials (such as melamine resin) or recycled natural products (such as wood chips) that are bonded under high pressure. The top layer is not wood but a detailed photographic image creating the look of wood (and in some cases, stone).
Engineered wood and laminate flooring systems are known as floating floors and are easy to install by interlocking the tongues and grooves on the planks without the need for glue or nails.
