Solid hardwood is uniform throughout, allowing it to be refinished multiple times over decades, but it is highly susceptible to expansion and contraction from humidity. Engineered hardwood utilizes a cross-layered core that makes it more dimensionally stable in varied climate conditions, such as basements or homes with radiant heating, though the number of times it can be refinished depends on the thickness of the top wear layer.

What is the difference between solid and engineered hardwood?
Solid hardwood consists of a single piece of wood milled from a tree, offering longevity and the ability to be sanded multiple times. Engineered hardwood features a layered construction with a real wood veneer atop plywood or composite, providing better stability in changing humidity.
