Tecnical Data Janka Hardness Scale

The Janka Hardness Scale determines the relative hardness of numerous wood species. The higher the number the harder the wood.

The Janka hardness test measures the force required to embed a .444-inch steel ball to half its diameter in wood. It is one of the best measures of the ability of a wood species to withstand denting and wear.

While Janka values give a general sense of hardness, many other factors also contribute to a wood floor's durability, including the type of cut (i.e. plainsawn, quartersawn), denseness of cell structure, and finish used.
