Particleboard
Definition and meaning of Particleboard in real estate.
Particleboard is an engineered wood product manufactured by mixing wood chips, sawmill shavings, and resin under heat and pressure. It is commonly used in subflooring (the rough wood layer under finished flooring), shelving, and low-cost furniture.
In more detail
This material is cheaper and more uniform than solid lumber or plywood, but it lacks structural strength and resists moisture poorly. When exposed to water, particleboard absorbs moisture, swells, and can eventually disintegrate or lose its structural integrity. For this reason, builders avoid using it in areas prone to dampness unless it is specially treated or sealed.
Home buyers and inspectors look for particleboard in older homes to ensure it has not suffered water damage in kitchens, bathrooms, or crawl spaces.

During a home inspection, the inspector noticed that the particleboard subflooring under the kitchen sink had swollen and begun to sag due to a slow, undetected leak from the garbage disposal.
Frequently asked questions
Is particleboard the same as medium-density fiberboard (MDF)?
No, particleboard is made from larger wood chips and shavings, whereas MDF is made from much finer wood fibers. MDF is denser, smoother, and generally stronger than particleboard, making it better for painted finishes.
Can particleboard subfloors be used under tile?
No, tile manufacturers do not recommend installing tile directly over particleboard because the material expands when wet and lacks the rigidity required to prevent grout and tiles from cracking.
