FIELD: construction.

SUBSTANCE: invention relates to the construction of sandwich panels for construction, namely for the manufacture of enclosing structures of buildings and structures, as well as roofing. The aim of the invention is to increase the strength of the panel under various types of load and at the same time maintain its sound insulation and fire resistance, as well as increase the thermal insulation properties, increase the service life of the panel, reduce its weight and reduce the cost. The sandwich panel includes two surface layers of metal bonded to the central part. The central part of the panel is made up of hexagonal elements in cross section, each of which is obtained by joint sintering of a fiberglass sleeve with compressed mineral wool placed in it in the form of a cylinder.
