Bio board (a 3-layer glued solid board) is made mainly of coniferous woody plants and consists of three layers glued on each other. The outer layers consist of continuous lamellas glued lengthwise. Central layer is glued from lamellas that are connected on each other lengthwise. After grinding, all the three layers are glued to one unit in such a manner that the central layer is glued under 90° angle against the top layers. Diversity of the assortment enables wide options of utilisation for modern furniture production, interior design and wooden houses.
