FIELD: construction.
SUBSTANCE: invention relates to construction elements of relatively small thickness for construction of separate parts of buildings, in particular to wooden wall panels. Said technical result is achieved due to the fact that the wooden wall panel contains rows of lamellae connected to each other by means of an adhesive joint; wherein at least part of the rows of lamellae consist of two lamellae of different width; characterized by that at least part of wide and narrow lamellae alternate in rows; at least part of the rows of lamellae are made with an air gap between the lamellae; width of the air gap is from 5 to 30 % of the width of the wall panel; lamellae are connected so that air gap of one row does not intersect with air gap of another row.
EFFECT: wider range of equipment and reduced heat conductivity of the wall panel while maintaining its strength.
