If the concept of Janka hardness is new to you, you’re not alone!
Even among seasoned lovers of interior design, many don’t have the faintest idea of what Janka hardness is, or that it plays a central role in determining the strength and durability of their hardwood floors.
As purveyors of oak and walnut floor planks, Oak & Broad is here to provide you with a basic understanding of the concept.
What is Janka Hardness?
Invented by Austrian wood researcher Gabriel Janka in 1906, this scale was designed to determine the exact hardness of different types of wood. Widely used in the interior design world, the Janka hardness scale allows people to choose the right hardwood for different environments and rooms.
Where Does this Scale Come From?
The formula uses a 2-inch by 2-inch by 6-inch piece of wood, and a 0.444-inch steel ball. The test determines the hardness of the wood by figuring out the PSI—or pounds per square inch—of force that’s needed to push this ball halfway into the wood.
The scale starts at zero—for the softest woods—and goes up to 4,000. Any wood near this upper limit would not be suitable for flooring, since it would be very difficult to saw through it.
What is Good Janka Rating?
Any wood species that is above a Janka rating of 1,000 is good enough for hardwood floors. Not that wood rated in the hundreds can’t be used for flooring, but softer wood is more susceptible to scratches and marks from foot traffic, furniture, high heels, and pets.
Why Does It Matter?
Typically, you’d think that the wood, the more durable it will be. However, keep in mind that if the wood is too tough, it will be difficult to run it through a mill. This means that if you like a particular type of hardwood, finding the right option requires some research. Not to mention that harder woods are usually more expensive.
This is where the Janka scale comes in handy. It allows you to find an ideal option that will suit your needs and your budget.
