Freudenberg Building Systems has developed Norament 925 Grano FS, a rubber floor covering that uses a low-emission, releasable adhesive to facilitate the installation, removal and reinstallation of the product. Nora rubber flooring is made from renewable natural rubber extracted from the sap of tropical rubber plants, as well as industrial rubber. Environmentally-safe pigments in Nora flooring are free of lead and other heavy metals, according to the company.
