All of our America Oak Flooring engineered wood products use the best raw materials from around the world. Our real wood surface layer uses White Oak from the United States, and our multi-layer Birch plywood are sourced from Russia. The cross-grained and multi layered plywood construction with open slots are designed and manufactured to increase the durability of our products while making the installation process easier and faster. Furthermore, we have recently become strategic business partners with Bona of Sweden, using their world famous coating on some of our best selling products. The beautiful finish of the Bona paint combined with our quality wood materials make American Oak Flooring products truly unique in the market place and deserve the utmost consideration in your purchase decision.
