Walnut floors and the Janka scale
We are building a new house and I love walnut floors. Our builder just told us that he doesn't think that it is a good idea for us (we are talking kitchen and dining area and we have small kids) I know that they are softer then oak (20% softer) but is that really significant? It seems as though oak is not a good reference point. When you compare it to the harder woods like brazilian cherry (82% harder then oak), Mahogany (109% harder then oak) or brazilian teak (174% harder then oak) the 20% difference between walnut and oak doesn't seem like much of a difference. Oak is everywhere and people with it don't seem to be scared off by its janka rating or concerned by potential scratches/dents. Is that 20% really significant? Or maybe I'm just trying to make an excuse to get the walnut. I'm most concerned about chair dents from the dining room set and marks from the stools in the kitchen. What are your thoughts?
