Acoustic lagging for ductwork is the best way to mitigate or reduce industrial noise which is usually defined as unwanted sound. Usually a common noise control issue comprises three basic components like noise source, the receiver, and the path.
Generally, industrial noise can exist in two forms like airborne and structure-borne. Airborne noise travels from a source to a receiver as a differential in atmospheric pressure and can travel in all directions. It has often seen that structure-borne noise is transmitted from a vibrating source to a receiver through a solid material and regenerated as airborne noise. As soon as the source, path and receiver get identified, four tools are used to control the unwanted noise. Such tools include absorption, barriers, damping and vibration isolation.
Acoustic pipe lagging ensures compliance with BCA and other specifier and building codes' Acoustic requirements. The unique construction of Pipe Acoustic Lagging means it acts as both a noise barrier as well as a noise absorber and hence provides double benefits.
Acoustic lagging for ductwork absorbers easily converts airborne acoustical energy into heat when sound waves strike the surface of a porous material and pass inside. Damping reduces structure-borne noise generated by a vibrating surface by adding mass to the surface. Best quality damping products are available in adhesive-backed sheets or in compound form that they may be sprayed onto the vibrating surface.
Acouustic pipe lagging ensures compliance with BCA and other specifier and building codes’ acoustic requirements. They are widely used in commercial buildings, shopping malls, hospitals, hotels, residential apartments, mixed use buildings, multi-level unit housings, occupied spaces, any pipes/ducts that needs breakout sound reduction.
The unique construction of acoustic lagging for ductwork pipes means it acts as both a noise absorber as well as a noise barrier and hence provide dual benefits. It’s highly dense and flexible mass layer which provides excellent sound reduction properties. As decoupling layer easily breaks the vibration path between the substrate and the mass barrier, it allows the vinyl external wrap to remain flexible to optimize performance.
Acoustic lagging for drainage pipes are made in a way to increase the sound absorption around the pipe, the closed cell structure gives an advantage that the material will not absorb or accumulate water or dirt resulting from leakage or maintenance work inside its structure.
Acoustic insulation offers high-performance composite acoustic pipe lagging product consisting of a reinforced aluminum foil faced, mass loaded flexible vinyl noise barrier bonded to a decoupling layer. The product was developed to reduce noise break-out from pipes, valves, fan housings and ductwork in commercial, industrial and domestic buildings. Such solution is ideal for both pipe and duct lagging applications.
