There are three types of noise common to air duct systems. Because of the sound-absorbing properties inherent in JM fiber glass insulation, it can help reduce all three kinds of noise.
Zoned systems with fans inside the ducts are sometimes the culprit. However, noise from the fan in the furnace or air conditioning equipment can also be transferred throughout the house via the ducts.
This is noise transferred from one room to another. Noise from the television or the vacuum cleaner or from someone talking on the phone can be transferred from the source all the way to the bedroom or home office, causing distractions when you need peace and quiet.
Not only does sheet metal conduct sound more than other materials, it also creates its own unique noises. When changes in temperature occur, sheet metal ducts and fittings expand or contract, causing popping sounds, squeaks and groans.
