Wood stability refers to how much an installed wood floor expands and contracts in relationship to the change in humidity.

As a unit of measure, that dimensional change is often compared with Northern Red Oak. If the percentage is higher than Northern Red Oak it is more stable and reacts less to moisture changes within the environment.

The hardness of a wood reflects its durability. When speaking of wood hardness, experts are referring to the ability of a wood species to with-stand indentations. Once again, the comparison is made with Northern Red Oak, whereas the higher number denotes a harder wood.
