Nowadays wood composites are an essential and the most useful material in wood industry. In wooden structures they are used for the production of partition walls, roof structures and for wall and ceiling coverings. The users of these boards aim for high-quality finished products, but the materials that they are made from often show various physical and mechanical properties. Therefore, our goal was to get information from random users about the usage, and the properties of the composite boards to analyse the information obtained, and to project a product having less defect and increased usability. Particle boards were tested according to standards pointing out the physical and mechanical properties. The 16 mm 5-layer board with a suitable density proved to be the best regarding to the mechanical strength, the only exception was the thickness swelling. A composite with improved qualities was made and at the same time the usability of the material was increased.
