Flooring Wood Species
Coswick flooring is manufactured from 5 different domestic and tropical wood species. White oak and ash flooring are classic choices that will fit most contemporary interiors. Flooring from American Walnut, Jatoba and Santos Mahogany is distinguished by exotic color tones and makes flooring the focal point of any space.
In woodworking and hardwood flooring manufacturing, different wood species are compared to one another using the Janka method. Janka is a test which measures (in pounds) the force required to drive a metal ball (11.28 mm in diameter) into the wood to the depth of ½ the ball’s diameter. The hardness of a given wood species is directly proportional to its Janka value: the higher the value, the higher the wood hardness.
Janka hardness test is calculated as an average between plain sawn and quarter sawn cuts and is meant to inform about structural properties of a given wood species, its resistance and durability.
White oak, one of the most popular wood species used in wood flooring manufacture, measures 1360 on the Janka scale. It is a very strong and hard wearing wood species; tannic acid in the wood protects it from insect and fungal attacks.
White ash measures 1320 on the Janka scale. Like white oak, it is a very strong and durable wood species, but ash is distinguished by being an elastic wood with excellent shock resistance properties.
American walnut is softer than oak or ash (measuring 1010 on the Janka scale), but the pronounced color difference between sapwood and heartwood make it a sought-after wood species. American walnut, like ash, has excellent shock resistance properties.
Jatoba is very durable and dens, and is one of the hardest wood species used for manufacture of hardwood flooring. Measuring 2350 on the Janka scale, it is nearly twice as hard as Northern red oak.
Santos Mahogany is one of the most sought after exotic wood species. It is distinguished by rich reddish brown color and very fine and even grain texture. Santos Mahogany measures 2200 on the Janka scale.
The table on the right shows how wood species used to manufacture Coswick flooring compare against one another according to Janka scale. More detailed information about each of the wood species is found under the corresponding tabs above.
