Large HVAC duct vibration and noise control

Acoustic and vibration isolation for large HVAC duct systems

Large HVAC ducts can transmit airborne noise, structure-borne vibration and resonance throughout a building. Proper acoustic and vibration isolation reduces noise transmission, prevents vibration from propagating through the supporting structure, and improves occupant comfort. Resilient supports, flexible connections and acoustic treatments ensure quieter operation, increased system reliability and long-term performance.

Solutions

Noise in HVAC ducts and pipes is not only generated by airflow. Mechanical vibrations can also be transmitted through rigid pipe supports and building structures, creating structure-borne noise, resonances and unwanted vibration in occupied spaces.

AMC Mecanocaucho SRS + Sylomer® acoustic hangers provide resilient decoupling between the pipework and the building structure. By reducing the transmission of structure-borne vibration, they minimise noise propagation, improve acoustic comfort and protect the installation, while maintaining the required load-bearing capacity and long-term stability.

Duct Vibration Isolation with Sylomer®

HVAC ducts passing through walls and floors can transmit structure-borne vibration and noise when rigidly connected to the building structure. Sylomer® resilient inserts elastically decouple the duct from the surrounding construction, significantly reducing vibration transmission and improving acoustic performance.

The resilient material also seals the annular gap around the penetration, helping to minimise air leakage while maintaining long-term elasticity and durability.

AMC MECANOCAUCHO PIPE RISER ISOLATION

As the buildings become taller, the loads and the problems related to pipe risers also become more complex. Pipe risers are subject to hydraulic forces due to the pressure changes, and also to thermal expansions and contractions.
