Fiberboard is an engineered wood product formed by breaking down wood into fibers, and then using a binder to form them into panels. Fiber board is used as a building material similar to plywood. Fiberboard holds glue and paint well, is flexible, and has a consistent size and strength. It also expands and contracts less than natural wood.
To create fiberboard, trees are debarked with a chain flail debarker and then chipped with a disc chipper. Chips that are too large are re-chipped. Smaller chips can be used as fuel.
