Argatherm Acoustix is a lightweight acoustic skim coat for smoothing sprayed acoustic plaster. Spherical expanded mineral fillers keep the film microporous, so sound still reaches the absorbing plaster underneath: the finished system rates NRC 0.65 over Diathonite Acoustix+. White, 2–5 mm total, for interior walls and ceilings.
