Engineered
Engineered wood is produced with three to five layers of hardwood. Each layer is stacked in a cross-grain configuration and bonded together under heat and pressure. As a result, engineered wood flooring is less likely to be affected by changes in humidity and can be installed at all levels of the home.
Solid
Solid wood is milled from a single 3/4" thick piece of hardwood. Because of its thickness, a solid hardwood floor can be sanded and refinished over several generations of use. Solid wood flooring expands and contracts with changes in your home's relative humidity.
