Engineered hardwood floors are made of multiple layers of wood, with a top layer of natural hardwood and a core made from high-density fiberboard or plywood. Unlike solid hardwood, which consists of a single piece of wood, engineered hardwood is more resistant to moisture and temperature changes. This makes it ideal for areas like basements or humid environments. Engineered hardwood floors offer the beauty of real wood with enhanced durability, making them a popular choice for modern homes.
