Johnsonite, a Tarkett company, introduced its Ecolibrium rubber wall base. Ecolibrium is manufactured with a proprietary patent-pending compound that combines rubber, olefin and natural filler — walnut and oyster shells. Ecolibrium contains more than five percent of its total weight in rapidly renewable materials along with pre-consumer recycled content. The walnut shell dust and oyster shells reduce the amount of necessary fillers and colorants in the products. Ecolibrium is flexible for ease of installation, has a smooth surface finish and is available in the 32 standard ColorMatch colors. Ecolibrium has no dye lots, guaranteeing exact color match. www.johnsonite.com
