Wood particles, expanded polystyrene and UF resin were used to make boards in laboratory conditions. Rotary - cut birch veneer was used for veneering of lightweight boards. The boards were made in a thickness of 18 mm and de nsity of 350, 450 and 550 kg/m 3 at the pressing temperature of 200 °С, pressure of 2 . 4 MPa and specific time of 0 . 23 min/mm. To make the boards , wood particles were mixed with expanded polystyrene at the weight ratio of 93:7. The UF glue consumption was 10 % of t he mass of absolutely dry wood particles. Modulus of rupture (MOR), modulus of elasticity (MOE), tensile strength perpendicular to the plane of board (IB), thickness swelling and water absorption of prepared particleboard were determined. It was foun d that veneering of lightweight particleboard by birch veneer improve their properties significantly . The results of research show that the MOR and MOE of veneered boards within density range of 350 - 550 kg/m 3 meet the requirements (for lightweight particle board) of EN 16368 (types LP1 and LP2). Only t he IB value of veneered boards with density of 550 kg/m 3 meets the requirements of EN 16368 (only type LP1). The MOR, MOE and IB of non - veneered boards also meet the requirements of EN 16368 (type LP1) except boards with the density of 350 kg/m 3 for MOR and MOE, and except densities of 350 and 450 kg/m 3 for IB.
