A derived timber material board, having at least three layers made of a derived timber material, at least a middle layer thereof being made of a mixture of derived timber material and a foamed plastic, is characterized in that the middle layer additionally has at least one foamed natural material. Disclosed is a method for manufacturing a timber board, in which each separate layer is poured of glued timber material. In at least one middle layer foamed natural products are added, primarily corn, rice or wheat. The poured layers under action of pressure and temperature are pressed in the board of required thickness. The natural products are foamed directly prior to or during pressing. |
