Fiberboard

From Wikipedia, the free encyclopedia

Fiberboard is a type of engineered wood product that is made out of wood fibers. Types of fiberboard (in order of increasing density) include particle board, medium-density fiberboard, and hardboard. Fiberboard is sometimes used as a synonym for particle board, but particle board usually refers to low-density fiberboard. Plywood is not a type of fiberboard, as it is made of thin sheets of wood, not wood fibers or particles. Fiberboard, particularly medium-density fiberboard (MDF), is heavily used in the furniture industry. For pieces that will be visible, a veneer of wood is often glued onto fiberboard to give it the appearance of conventional wood.

Certain types of fiberboard can be considered "green" building products. Consisting of bio-based, secondary raw materials (wood chip or sugarcane fibers) recovered from within 100 miles of manufacturing facilities, the binding agent used in this type of fiberboard is an all-natural product, consisting of vegetable starch containing no added formaldehydes. The Leardership in Energy and Environmental Design (LEED) Green Building Rating Systemtm has accredited Knight-Celotex fiberboard to contribute to the design, construction, and operation of high performance green buildings.

Fiberboard, classified by ASTM C208 (Standard Specification for Cellulosic Fiber Insulating Board,) has many benefits and is used in residential and commercial construction. Different uses and applications include:

sound proofing/deadening, structural sheathing, low-slope roofing, sound deadening flooring underlayment,
