FIELD: construction.
SUBSTANCE: invention relates to construction, particularly wood construction, and woodworking industry. Disclosed is a bar having two end faces perpendicular to the longitudinal axis of the bar, two opposite faces that pass parallel to the longitudinal axis of the bar and form its planes in the finished wall, and two opposite profiled faces passing parallel to longitudinal axis of bar and containing slots passing along length of bar, wherein the profiled faces have the same profile, comprising straight sections passing parallel to the faces P or along them, two slots of substantially rectangular cross-section and at least one slot of substantially semi-circular cross-section, wherein said profile is mirror-symmetric.
