A rigid composite board of pressed cellulose fibers used as a building material. First patented in 1858, fiberboards were composed of wood chips or plant fibers, such as Grass, Reed, Straw, Bagasse (Celotex), Jute, Flax, or Hemp. Manufacturers have also recycled waste materials such as Sawdust, Bark, oat hulls, spent hops, newspaper (Homasote®) and peanut shells. The fibers are compressed and bonded with heat and pressure. Many fiberboards are held together by the interlocking fibers and natural adhesives (wet process); other fiberboards have additional adhesive components such as Urea formaldehyde resin, Water glass, Dextrin, Asphalt, Rosin, Paraffin wax, Plaster, and/or Clay. The standard size for fiberboards is 4 x 8 feet. Very dense fiberboard is called hardboard (see also Masonite®). Some commercially available formaldehyde-free fiberboards are Masonite® Presdwood®, Medex, Medite II and Iso-board (Hatchfield 2002). Fiberboards are generally classified as low-density (Celotex, etc.), medium-density (Medex, Medite, etc.), or high-density (Masonite®, Upson Board, Marinite®, Homasote®, etc.).
