Is hardwood harder than softwood?
One of the big misunderstandings about wood floors is the difference between “hardwoods” and “softwoods.” While hardwoods in the aggregate tend to have higher Janka hardness scores than softwoods, that doesn’t mean that every hardwood is harder than every softwood. In fact, hardwood and softwood are only nicknames for a more scientific separation of species. Hardwoods are actually angiosperms, which means “enclosed seed.” Angiosperm trees have mature seeds that grow in a fruit or a nut, like oak and cherry. Gymnosperm trees have naked seeds that are carried in things like pine cones. Species such as pines, firs, and cedars are gymnosperms. While it might be called a softwood, Douglas fir is actually harder than some angiosperm hardwoods, such as chestnut.
Is Douglas Fir hardwood durable?
Douglas fir is a very durable hardwood flooring option. We need only look to the early twentieth century houses of the Pacific Northwest, many of which have Douglas fir floors that have retained their quality for nearly 100 years, in order to see this. The reason that Douglas fir is sometimes mistaken as a less durable flooring material is because it has a relatively low Janka score. The Janka hardness test is the measurement by which a hardwood species’ “hardness” is determined. The score is based on how much force it takes to embed a .444-inch steel ball halfway into a plank of wood. Montana Douglas fir has a Janka score of 770, meaning it takes 770 pounds of force to do this. Clearly, unless you’re shooting at your floor regularly, this is an adequate level of hardness. Durable Douglas Fir hardwood flooring makes up for its comparatively low Janka rating in other ways though. It has an excellent modulus of elasticity, meaning it can bend and return to its original shape, unlike many brittle hardwoods, as well as good ratings for tension parallel-to-grain, shear, and compression.
