Fiberboard Core

Flooring layers

Definition of Fiberboard Core

A combination of soft and hard wood particles and a binding agent, like resin, used as the internal structure of hardwood flooring. 

A fiberboard core is heated and compressed to create a dense board that’s not as durable as other engineered hardwood flooring cores, like plywood and high-density fiberboard (HDF).

It’s affordable and versatile, so in addition to its use as a flooring material, it’s used to manufacture furniture, door panels, and cabinetry.

Example of Fiberboard Core in a Sentence

“A fiberboard core is denser, harder, and stronger than an MDF core.”
