Our engineered bamboo floors give you great versatility in installation and style. They are available in 6 distinct colors, 2 grain styles and in 2 different species of bamboo. In an engineered floor, the direction of the grain runs ‚¬Ëœnorth to south' on the top and bottom layers and 'east to west' in the core. This means that the average force of the grains throughout all of the three layers is zero for maximum stability even in the changing temperatures and humidity levels that floors are subjected to throughout the year no matter what climate you live in. This is why high-quality engineered floors are suitable over radiant-heat, slab, plywood and in condominiums. Combining the absolute best engineered floor system with the hardest species of bamboo known to man results in what is objectively the best bamboo floor in the world. Protecting this uniquely great floor is a finish made of the highest-grade Aluminum-Oxide with a hardened urethane scratch resistant top coat that can be recoated without sanding. When we boast that our bamboo floors are the best on the market we do so with objectivity, confidence and pride. The floor uses two glues, one of which is formaldehyde free glue and one of which is E-1 compliant. The finish is formaldehyde free and comes with a 50 year warranty against finish wear-through. Our impeccable milled floors are easy to install, virtually seamless and will not develop gaps over time.
