FIELD: woodworking industry.
SUBSTANCE: invention relates to the woodworking industry, namely to the wooden panels. Wooden panel consists of connected together by metal rods wooden workpieces. Wooden workpieces are half-logs, wherein the upper and lower half-logs contain blind rectangular groove, which is made in the half-log longitudinal direction in its central area with offsets from the half-log end and side edges. Located between the upper and lower half-logs half-logs contain end-to-end rectangular groove in the half-logs longitudinal direction in its central region with offsets from the half-log end and side edges, wherein the half-logs are connected by metal rods so, that the grooves form filled with the heat-insulating material cavity.
EFFECT: technical result consists in increase in the panel heat insulation properties.
