Acoustic Lagging
Pipe & Duct Lagging
Acoustic Lagging is a composite wrap applied around pipes, ducts and mechanical services to contain the noise they radiate into occupied spaces.
The system pairs a limp-mass barrier layer with a decoupling absorptive layer, so the barrier blocks airborne noise while the soft layer isolates it from the pipe wall.
Features
Reduces noise radiated from pipes, ducts and services
Limp-mass barrier with decoupling absorptive layer
Flexible — wraps around bends, valves and fittings
Applied on site over existing services
Suitable for retrofit without replacing pipework
Optional foil or reinforced facing
Applications
Soil and waste stacks in apartments and hotels, HVAC ductwork above occupied ceilings, pump and chiller pipework, plant rooms, and any service run passing through noise-sensitive areas.
