Janka Hardness Scale For Wood Flooring Species
The Janka hardness test is a measurement of the force necessary to embed a .444-inch steel ball to half its diameter in wood. It is the industry standard for gauging the ability of various species to tolerate denting and normal wear, as well as being a good indication of the effort required to either nail or saw the particular wood.
What you need to know:
Janka, short for the Janka Scale or Janka Hardness Rating, is a way of
communicating how hard a wood is. The Janka Hardness Chart lists woods
by their rating. Though it's good to know a trees hardness, using the
Janka table to help you buy your hardwood flooring may not make sense;
just because a wood is hard doesn't make it a good flooring option. The
Janka hardwood flooring test is done on both the side and end of wood.
Janka ratings make it easy for people to discuss the durability of different
woods. Use Janka as part of your decision making processs, but not the
only factor. *
