In many commercial buildings, exposed piping systems run above ceilings, along corridors, or through open plenum spaces. While these systems are essential for heating, cooling, and water distribution, they often become unintended noise sources. When fluid velocity increases or pumps cycle on and off, pipe walls vibrate and radiate airborne sound into adjacent spaces. This results in persistent background noise that affects daily operations.
In office environments and shared workspaces, radiated pipe noise can reach 58–65 dB(A) during peak flow conditions. In quiet environments, anything above 55 dB(A) begins to interfere with concentration and speech clarity. Over time, this elevated background noise contributes to employee fatigue, reduced focus, and lower productivity. In healthcare or educational facilities, the impact can be even more disruptive.
The root cause is typically airborne and structure-borne pipe noise transmission. Standard insulation provides thermal control but does little to block sound radiation. Without sufficient mass and damping, the pipe surface acts like a vibrating speaker.
The DuctaSil® B10LAG™ II Pipe & Duct Barrier System solves this problem by combining a high-density mass-loaded vinyl barrier with an absorptive fiberglass decoupler layer. This composite design significantly increases sound transmission loss (STL) and reduces vibratory energy. In most commercial applications, breakout levels can be reduced by 8–15 dB, lowering ambient noise from 62 dB(A) down to a healthier 47–52 dB(A) range. This reduction brings mechanical noise within recommended comfort thresholds for offices and institutional buildings.
