What is the difference between engineered and solid hardwood?
A solid hardwood floor has more movement than an engineered hardwood floor. It will expand and contract more, responding to changes in temperature and humidity. Because of this, only engineered wood is recommended for below grade installations. Doug Robinson, of Certified Carpet Distributors, Inc. (distributors of carpet, hardwood, ceramic, and vinyl flooring materials) explains how engineered wood, especially that with a dry saw face, has the beauty of natural wood but is more stable. It can be recoated endless times, and refinished at least one if a color change is desired. Engineered wood with a greater number of layers is better as it is 70% more stable than a solid.
