As the name would imply, engineered hardwood is engineered and consisting of many layers. The outer layer is going to show the species of wood that you choose for your floors. It is a thin hardwood veneer laid on top of layers of plywood. Sometimes, the inner layers will consist of either plywood, hardwood, or fiberboard. Whatever the material, the layering aspect of engineered flooring means that you get the beauty of solid hardwood floors in your choice of species, as well as a much more stable and climate-resistant product.
