The Janka hardness test measures the resistance of a sample of wood to denting and wear. The higher the number the harder the surface of the wood. The harder the surface the more durable the floor; or rather the better it takes abuse. Douglas fir for instance has a Janka rating of 660lbs, which is incredibly soft compared to other types of hardwoods. Whereas Cali Bamboo fossilized hardwood products exceed 5,000 lbs. Two of our most common products which are oak hardwoods, Red Oak (1,290lbs) and White Oak (1,360lbs) are relatively close in Janka hardness. Depending on the needs of your home the Janka hardness scale can be of great use to you.
