Product Information norament ® 920

norament ® 920 is an one-coloured, extremely fire-resistant and halogen-free rubber flooring for extremely heavy traffic areas. norament ® 920 is largely resistant to oils and greases and offers all the advantages our customers rightfully expect from a resilient floor covering, too. Exposure to extreme stresses impairs neither the functionality nor its visual appearance.
