For Teragren bamboo flooring, stair parts, trim, panels and veneer, we use only Optimum 5.5™ Moso bamboo (Phyllostachys pubescens) known for its dense fibers and grown in the Zhejiang Province of China. We also require that the bamboo is sustainably harvested at maturity, every 5-1/2 to 6 years. With these specifications, we avoid product performance problems like cupping and warping associated with young, soft and often-inexpensive bamboo that is harvested to soon. As a result, Teragren products are exceptionally durable and our source plants remain vigorous and healthy harvest after harvest. In addition to relieving pressure on degraded forests, bamboo contributes to efforts to reduce global warming. Bamboo's leafy canopy releases 35 percent more oxygen than a comparable cluster of hardwood trees, especially when you consider that the bamboo re-grows and reproduces a canopy many times in its lifespan. In the renewing process, the plant grabs carbon from the air and holds it within its stalk and root system where, in nature, it is not released until the soil, in which the plant decomposes, is turned. Products made from bamboo take that carbon out of circulation. Teragren bamboo products harvested and manufactured correctly can last for many generations, keeping carbon locked up over the life of the products and helping to offset carbon usage that occurs in shipping our products to market.

If you are one of the growing number of consumers, design professionals and builders seeking ways to incorporate "green" products into your home and projects, you will find Teragren an experienced partner and valuable resource. From the moment our company was founded in 1994 (under the name of "TimberGrass"), we have been committed to developing and manufacturing beautiful bamboo products that: Reduce dependence on dwindling timber resources. Rely on renewable-resource materials. Adhere to stringent, environmentally sensitive specifications. Promote green building. Help neutralize our company's environmental footprint
