FIELD: construction.
SUBSTANCE: panel comprises a ground renewable component in amount from approximately 0.1% to approximately 95% by weight. In a version of realisation the panel has at least one core and comprises: from approximately 0.1% to approximately 95% by weight of the ground renewable component, from approximately 0.1% to approximately 95% by weight of one or more inorganic fibres, from 0.1% to 30% by weight of one or more binding substances, relative to dry weight of the panel. In a version of realisation the ground renewable component has such distribution of particle sizes, when less than 5% of particles are caught by a sieve with holes sized as 0.312 inches, and less than 5% particles go through a sieve with holes sized as 0.059 inches. The method to manufacture soundproof panels includes the following stages, when: they select a ground renewable component; sort the ground renewable component to produce the necessary distribution of particle sizes; combine the ground renewable component, fibres and binding substance with water; prepare a water slurry; form the main mat from the slurry on a wire net with holes; remove at least some water from the main mat; and perform final treatment of the specified main mat for formation of the soundproof panel.
EFFECT: invention makes it possible to improve acoustic and physical properties of a panel.
