FIELD: wood-working industry. SUBSTANCE: wood member consists at least of two layers of wood; at least one layer (10-10f) of wood is made at least of one blank (24,24'), which at least on one side and/or on separate sections is furnished with structure (12,12'). Wood layers (10',10'', 10''') are placed obliquely to one another, the structure, respectively slots (12a, 12b, 12c) of layers (10', 10'', 10'''), preferably pass uniformly obliquely to one another. EFFECT: enhanced coefficients of heat- and sound- insulation of wood member, reduced waste. 11 cl, 14 dwg
