AST® E acoustic
In acoustic applications, both, ordinary Paroc Panel System panels and perforated acoustic panels can be used. Our acoustic panels have a perforated facing on one side to provide better sound absorption. It can be used for partition walls and ceilings in normal dry internal climatic conditions. In ceiling application the perforated panel surface is always on the lower side.

Sound absorption
Practical sound absorption coefficient
In Standard execution Paroc Panels have a steel sheet facing. Thus the sound absorption acts like a reflecting surface. Paroc acoustic panels have a perforated facing on one surdace which improves the panel’s sound absorption properties. It can be used in normal dry interal climatic conditions.
