Bark represents 10 % to 20 % of the tree mass and is mostly used for energy production and horticultural purposes. The greater part of the bark produced in the process of removing the bark in the forest, at sawmills, in the production of wood panel composites or in the production of pulp for the paper industry, is burned for biomass energy, while a smaller proportion of bark is used for horticultural purposes (landscaping) and the pharmaceutical and leather industries. Because of this, in recent years there has been a search for other possible uses of this material, including the production of various ligno-cellulose composites. Although the disintegration of bark gives, from a morphological aspect, less desirable forms of wood particles, we produced three-layer chipboards which we compared with chipboards made from spruce particles. Based on the results, we can say that chipboards made from bark particles are suitable for use in the furniture industry. They are less bending resistant, but they can be used in rooms or environments with higher air humidity, due to lower water absorption and thickness swelling. If we assume that we use a relatively more favourable material, which is mostly treated as a residue of log processing, the bark represents an interesting alternative to the established and known materials in the production of chipboards.
