Modern Nature Oak adds a contemporary and natural feel to any space. With knots and a freshly-cut, untreated look, it's a great match for a young, modern country style. The plank design is perfect for rooms where you want the look of real wood, but the warmth, softness and waterproof properties of vinyl. For commercial applications where a glue down floor may be preferred, we recommend our Optimum quality level. Optimum floors are easily glued to a level subfloor using Pergo vinyl glue. This glue is of the highest quality and has been specially developed for use with Pergo vinyl flooríng.
