Construction
Solid hardwood is one piece of wood through its thickness. Engineered hardwood has a real wood wear layer bonded to a plywood or composite core.
Comparison
Key differences that usually matter for homeowners:
- Refinishing: solid can typically be sanded more times; engineered depends on wear layer thickness
- Stability: engineered cores generally move less with humidity
- Installation: engineered options include glue-down and floating, and some suit concrete slabs
- Matching an older floor: solid site-finished flooring is usually easier to blend
Frequently asked questions
Which lasts longer?
Lifespan depends on wear layer, maintenance and use. A thick solid floor offers more sanding opportunities; a thin engineered wear layer offers fewer.
