We offer several different subspecies and finishes of oak flooring. But did you know that “Oak” is a term that can be associated as part of the 400 species of trees and shrubs that share this common name? A native to the northern hemisphere, oak has a density of about 0.75 g/cm³ which makes it one of the strongest woods. The oak itself is a common symbol of strength and endurance.
