Engineered Hardwood can be installed where solid wood cannot be installed. Engineered wood flooring is built up of cross-layers of wood. It can consists of three up to ten layers that are glued together. This multi-ply structure gives engineered wood superior stability, greater than solid wood, which reduces concerns associated with shrinking twisting or expanding when there is temperature and humidity changes. The actual top layer is made of real wood. Engineered hardwoods are a great choice for finished basements. They can be installed directly onto to concrete – whereas, solid wood floors cannot. Depending on construction type, either nail, glue down or click-locking technology methods may be used as an installation option.
