    Unit of Work

    Acoustic insulation at low frequencies on floor formed by:
    Distribution of rubber acoustic shock absorber according to overload of use between rock wool panel of density 100 kg/m³ and thickness 30 mm ROCDAN® 233/30 and protected by chemically cross-linked and foamed polyethylene sheet, 10 mm thick, IMPACTODAN® 10 fixed together with self-adhesive cross-linked polyethylene tape of 3 mm thick , Overlap tape 70 (Cinta de solape), mesh reinforced mortar with at least 6 cm thick, separated from the structure and installations by using peripheral band tape 200 (desolidarizador perimetral), ready to install the finishing.
