Ecolibrium Rubber Wall Base is manufactured with a proprietary patent-pending compound that combines rubber, olefin and natural filler–walnut and oyster shells. Over five percent of Ecolibrium's total weight is rapidly renewable materials, in addition to pre-consumer recycled content. The natural filler reduces the amount of necessary colorants in the products. Ecolibrium is FloorScore certified, can contribute to LEED points and is flexible for ease of installation.
