Amber Edge Grain prefinished bamboo flooring is a sleek, contemporary floor for the environmentally conscious. Rectangular bamboo strips are cut from the stalk, creating two wide sides (flat grain) and two thin sides (edge grain). With the edge grain floors, the wide sides are laminated together, so that the finished surface shows the edge of the grain. It has a beautiful, natural understated look. And it's very durable. Environmentally, Plyboo Edge Grain is hard to beat, made of sustainably grown bamboo and free of formaldehyde or other harsh chemicals.
