In multifamily residential construction, maintaining acoustic separation between units is essential. While walls and floor assemblies are often designed to meet STC requirements, ductwork passing between units can become an overlooked flanking path. This leads to noise transmission between apartments through mechanical systems.
When ducts are suspended above ceilings or routed through shared framing cavities, breakout noise can radiate into adjacent living spaces. Airflow turbulence and duct vibration contribute to a persistent ceiling hum that residents may notice during peak operation hours. Even when sound levels are within code limits, they may still impact perceived comfort.
Effective apartment building noise control solutions must address both structural assemblies and mechanical infrastructure. Increasing surface mass on duct exteriors reduces airborne transmission before it enters wall cavities. Without treatment, duct walls continue to act as radiating surfaces.
The DuctaSil® B10Lag™ Pipe & Duct Barrier System enhances acoustic performance in residential buildings by reducing breakout noise at its origin. The composite barrier system improves sound transmission loss while maintaining flexibility for installation around complex duct geometries. This approach supports long-term tenant satisfaction and minimizes mechanical noise complaints.
