MDF FR are non-load-bearing boards with improved fire retardant properties and are manufactured in compliance with European standard EN 622-5 where they are defined as boards for general use in dry conditions. MDF FR are increasingly used particularly in public spaces where stringent fire regulations must be met. Boards meet strict requirements which include improved fire resistance and especially the ability not to contribute to fire spread and not to form burning droplets. According to EN 13501-1 boards are classified B-s2, d0 in terms of reaction to fire. Boards are produced red-colored fiber as standard.
