Medium-density fire retardant fiberboards are non-load-bearing boards with enhanced fire-retardant properties and are manufactured in accordance with European Standard EN 622-5, where they are defined as boards for general use under dry conditions. Fire retardant medium density fiberboards are increasingly used in public areas where strict combustion regulations must be met. The sheets meet stringent requirements for enhanced fire resistance and in particular the ability to prevent the spread of fire and not form burning droplets. Plates in accordance with EN 13501-1, fire resistance; in terms of B-s2, it is classified as d0. Boards are produced from red colored fibers as standard.
