Red Oak is the most common of all the US hardwoods used in residential flooring. It is a wood against which other species are usually compared. The hardness varies with the source of the trees. Most strip oak (2-¼” wide) is mass pro-duced in the south and from the softer species of local trees. Housatonic wide plank flooring is made from northern oak which is generally 20% harder than strip oak. Color tends to be quite uniform in Red Oak, with the heartwood only slightly darker than the sapwood and flooring is readily stained in a wide range of shades.
