Engineered hardwood flooring is sold as boards made up of a hardwood surface (called the wear layer) glued on a plywood base. Engineered hardwood flooring is real wood flooring, but is more stable than solid wood. Engineered wood flooring is less susceptible to shrinking and expanding with changes in temperatures and humidity while the multiple wood layers in engineered hardwood make it very durable. The boards can be glued directly onto concrete, an acoustic underlay, or even a subfloor with a floor heating system. They can also be stapled to a plywood subfloor. This is the perfect floor covering for condominiums, basements, and commercial uses.
The quality of an engineered wood floor can be determined by looking at four factors: the thickness of the wear layer, the number of plies that the plywood is made of, the surface cutting procedure used, and the precision of the cut.
