FIELD: construction. ^ SUBSTANCE: invention relates to construction technologies and, particularly, to three-layer panels. The panel contains hard framework made of wood bars, non-structural heat insulation and sheeting. The wood bars are made plate-glued. The glued interlayer planes are parallel to sheeting plane. The reinforcing mesh is embedded into the glued interlayer along the whole length of wood bars and projects to 0.1/0.25 of bar width in outward direction and, at least, at one side of the bars. Besides, bar plates are grooved from the wide side and adjacent bar grooves are located in a staggered order. ^ EFFECT: improved panel strength and stability of shape. ^ 3 cl, 3 dwg |
