摘要

Acoustic insulating panel, of the polyaminary built-insulated acoustic insulating panels, with very small cellular polymeric plastic materials and very low-density products, essentially characterized by being configured in triple plate, united the central (2), of the covering type asphalt and of small thickness, to the two side extremes (1) and (3) through an adequate adhesive (4) conventional, being the sheet (1) of greater thickness, in agglomerate of pieces (1.1) irregular, of a very low density polyurethane, whereas the external (3) external plate, also in plastic polymer, of very low density polyurethane, is less thicker than the lámina (1) and is previously molded, with a smooth face and some resolutions of diverse forms (Machine-translation by Google Translate, not legally binding)
