However, solid wood can never be installed below grade, i.e., in basement rooms, and must be acclimated before installation.
Engineered hardwood flooring is a great alternative for basement areas, as these materials do not react to humidity, dampness, moisture, or temperature changes. No expansion gaps are needed, and the need for acclimation varies, based on certain conditions.
Engineered hardwood also offers great benefits like a solid construction featuring plies of wood onto which a veneer of the real hardwood of your choice is laid. A top wear layer also protects against wear and damage, leaving you with a gorgeous floor covering.
