An important characteristic that you should take into consideration when shopping for species of hardwood flooring is the hardness factor. If you been shopping around for a wood product, you may recognize the term Janka Table. The Janka table organizes hardness data. This is not a number that is via specific data, but rather by relative data. In other words, the Janka rating of unfinished hardwood flooring by itself means nothing other than to compare it to other woods. Both red and white oak is considered to be relatively hard woods. The Janka rating on red oak is 1290, while white oak rates a bit higher at 1360. Oak is considered relatively hard compared to other species, and with its high customer demand, it's also in a cost-efficient price range.
