As those in the flooring and construction industries know, the Janka scale of hardness is a measure of “the relative hardness of woods”. According to the ‘scale’, the hardest commercially available wood is Hickory; the softest is Aspen; and soft Maple and Cherry are mid-range. But with the introduction and popularity of engineered flooring products, it’s become evident that all the components of a flooring product must be taken into consideration when calculating Janka ratings. This article from Hardwood Floors magazine, as well as this one, point out that while a flooring product’s top wear layer might have a high Janka rating, the core might be made of a much softer wood. Depending on the thickness of the top wear layer, dents could telegraph into the softer core.
