Pipe and duct work is an essential part of any HVAC system, but it can also be a source of the noise. Pipe and duct barriers are designed to reduce the transmission of sound through these systems, and they can be an effective way to reduce noise levels in your home or office. Pipe and duct barriers are typically made of foam or other sound-deadening materials, and they are installed around the perimeter of the pipe or ductwork. In some cases, Pipe Barrier and duct barriers can also be used to improve the performance of the HVAC system by reducing air leakage. If you are concerned about noise from your HVAC system, contact a qualified engineer to discuss the best options for reducing noise levels.
