Chipboard is made from the least used bits from the forest. These generally are debarked and cut down and mixed into fine and coarse pieces. This is then layered and glued at the same time with the fine pieces to the outside and the coarse pieces to the inside. The higher the density the stronger the board, hence three grades standard, furniture and flooring. To achieve a moisture resistant grade moisture resistant glue is added instead of standard glue. This product is used for furniture, fixed seating, chairs etc.
