Resumo: The present work evaluates the acoustic isolation of a wall of plates pre-molded, constructed with recycled material (rubber of tires), used in popular constructions the two decades, in the city of Santa Cruz do Sul - RS. The constructive system is elaborated in part with hand of jail workmanship (plates are produced in the Prison) and by housing building with 60,00 and 40,00 m2 of area using the system of collective mobilization. The social reach of the project achieved an international awarding. In a joint work, supported for the FINEP and Municipal City hall of Santa Cruz of the South, the UFSM and the UNISC are searching the improvement of this constructive system. Tests in laboratories had been implemented in acoustic areas, detecting low sonorous isolation, given that the plates are thin and they don t fit properly, without adhesive or covering. They realized, however, the following result of Rw = 40 dB, with adhesive and with the installation of the wooden internal covering, according as usual job of the inhabitants. The cost constitutes one of the priorities item for the viability of the program, but measured as the use of isolate mortar among the plates and next the pillars of concrete of the structure, it will have to be taken to improve the acoustic isolation of the construction.
