Reducing Air Movement Noise Inside the Duct
Acoustic duct lining is an internal fiberglass or foam material installed inside a duct's interior surface, distinct from the exterior insulation wrap used for thermal purposes, and it works by absorbing sound energy generated by air movement before that noise travels down the duct and out through a register into an occupied space. This differs from vibration isolation, which addresses noise transmitted through the duct's connection to the building structure, acoustic lining addresses noise generated by and traveling through the air stream itself, which becomes significant in duct sections carrying higher air velocities, such as runs near the air handler or in systems with undersized ductwork forcing air to move faster than ideal.
We install acoustic lining most often in duct sections close to the equipment, where air velocity is naturally highest before it has spread out across multiple branch takeoffs, and in any run serving a bedroom or media room where even modest air movement noise is more noticeable due to the room's use and typically lower ambient noise level. The lining material is installed against the interior duct wall during fabrication or, for existing rigid duct, applied during a retrofit where a section of duct is accessible enough to line without full replacement. We use lining rated for HVAC duct interior use specifically, since it needs to withstand continuous airflow and moisture exposure without degrading or releasing fibers into the airstream.
In Georgetown homes, acoustic lining is particularly useful for bedrooms located near the air handler, a common layout in homes where the equipment closet sits centrally located near the primary suite, and in home theaters or offices where a quiet environment matters more than in typical living spaces. It is worth noting that acoustic lining is not a fix for airflow noise caused by an undersized duct or restriction, in those cases addressing the underlying sizing or restriction issue reduces the noise at its source, while lining is most effective as a complement to correctly sized ductwork rather than a substitute for it. Acoustic lining installation typically runs 300 to 750 dollars depending on the length of duct treated and whether it is installed during new fabrication or retrofitted into existing duct.
