When you are in a market for new floors for the first time, it’s easy to get lost in the abundance of options. Hardwood remains one of the most popular floor coverings, but even after you settle with hardwood, you’ll need to decide which type of wood will work best for your needs. “Hardwood” is a collective term used to describe a variety of tree species. The wood from these trees differs in color, grain, moisture resistance, and, most importantly, hardness.
Hardness of wood is measured by Janka scale that rates tree species according to their resilience to applied force. To be specific, the hardness number assigned to a certain wood variety corresponds to the force (measured in pound-force) required to embed a 0.444 inch steel ball to half its diameter into the wood’s surface.
Depending on the position of the board and grain direction during the test, “side” or “end” hardness is determined. Side testing score (force applied perpendicular to the grain) is usually the number you’ll see on Janka scale. The higher the number – the harder the wood.
The purpose of the Janka test is to measure wood’s resistance to denting, which is an important thing to know when you are considering a particular wood type for flooring purposes. If you plan to install hardwood in a high-traffic area, you don’t want it to wear down too fast from the furniture weight, walking, pet scratches, or things that fall by accident.
The Janka hardness scale is not hundred percent accurate, but it can serve as a general guide to determine relative hardness of one species of wood compared to another. Red oak has been the most popular wood floor choice in the U.S. and is considered an industry standard of hardness with its rating of 1290.
Although wood hardness is important, don’t forget that such factors as finish and plank construction will also affect durability of your floor. Evaluate the traffic intensity and other conditions to make sure the hardwood you choose is up to the task. If you have dogs in the house, you might want to go for something like hickory, some bamboo varieties, or Brazilian hardwoods. They are less prone to denting than red oak and will serve you longer before you’ll have to refinish.
