The cork-based acoustic plaster Diathonite Acoustix was chosen as the material to carry out the sound absorption intervention in the over 5000 m2 of ceilings in the new underground car park built in Lisbon, close to the famous Alfama district and on the banks of the Tejo river. The project, carried out by the prestigious Atelier of the Architect João Luís Carrilho da Graça, involved the application by spraying Diathonite Acoustix with a thickness of 30 mm on the ceilings of the building, laid in two coats of 15 mm each, with the aid of the Polites 140 fiberglass mesh between one coat and the other, since it was a ceiling application. Afterwards, to combine the acoustic requirement with an aesthetic aspect that would guarantee an almost smooth finish, Argatherm Acoustix was used as an acoustic smoother, which thanks to its microporosities allows the system to be very good in terms of absorption, while maintaining a fine and uniform texture.
