How does PU Foam perform acoustically?

While primarily a thermal insulator, PU foam provides reasonable acoustic performance, particularly for impact noise reduction. Its closed-cell structure is less effective for airborne sound absorption compared to open-cell materials. For acoustic applications, specialized perforated or open-cell PU products are available. In typical building applications, PU contributes to overall sound reduction when used in wall and roof assemblies, but should be combined with other materials for comprehensive acoustic control.
