FIELD: building, particularly building members made of fibers, chips, vegetable stems or the like.
SUBSTANCE: large-sized panel has length of at least 7 m, specific weight at zero humidity of not more than 700 kg/m3 and 12-50 mm thickness. The panel consists of at least three layers each formed of compacted shavings provided with binding material. The shavings of neighboring layers are oriented in opposite directions. Shavings of every second layer are oriented in the same direction. Central layers consist of shavings have 90-180 mm length, 5-30 mm width and 0.4-1 mm thickness. The panel has modulus of elasticity in main load application direction of at least 7000 N/mm2.
EFFECT: increased mechanical and processing characteristics.
