The NORTH AMERICAN FIBERBOARD ASSOCIATION (NAFA) is the national trade organization of manufacturers of cellulosic fiberboard products used for residential and commercial construction, commercial products, and packaging.

NAFA serves as the central clearinghouse for industry and technical information for architects, builders, contractors, distributors, dealers, government agencies, and the general public. NAFA also works with government and private organizations to develop and improve industry standards and specifications and update building codes.

DEFINITION OF FIBERBOARD
Fiberboard (cellulosic fiber) – structural and decorative – is a fibrous-felted, homogeneous panel made from ligno-cellulosic fibers – usually wood  – which has a density of less than 31 lb/ft3 (497 kg/m3), but more than 10 lb/ft3 (160 kg/m3). Fiberboard is characterized by an integral bond which is produced by interfelting the fibers, but which has not been consolidated under heat and pressure as a separate stage in manufacture. Other materials may be added to fiberboard during manufacture to improve certain properties.

Fiberboard products are manufactured to the various types and grades defined by the ASTM C208 (Standard Specification for Cellulosic Fiber Insulating Board) and/or CAN/ULC-S706 (Standard for Wood Fibre Insulating Boards for Buildings). Copies of ASTM C208 may be obtained from the American Society of Testing and Materials (ASTM), 100 Barr Harbor Dr., W., Conshohocken, PA 19428-2959. Phone 610.832.9500 / Fax 610.832.9555  *Contact ASTM*  Copies of CAN/ULC-S706 may be obtained from Underwriters of Canada Standards Department 200-400 Laurier Avenue West, Ottawa, Ontario K1R 7X6. Phone 1.866.9373.4 / Fax 613.231.5977  *Contact ULC*
