How do you soundproof ducting?
How to Soundproof Ductwork and Vents in Your Home
- Make Repairs to the vent or ductwork.
- Choose Sound Absorbing or Soundproofing Materials For Your Vents or Ductwork.
- Insulate the Ducts With Liners & Vents With Acoustic Foam.
- Cover Unused Vents to Dampen Sound.
What is acoustical duct liner?
What is duct liner used for? Duct liner is a product that is used to line the inside of the duct. Lining a duct with elastomeric foam offers thermal protection from energy loss and condensation control, and also provides sound absorption and vibration damping from airborne and structure-borne HVAC noise.
What is acoustic lining in HVAC?
Quiet Natural Fiber Liner is used primarily as an acoustic duct liner designed for HVAC sheet metal to absorb unwanted noise from multiple sources. Quiet Liner HVAC acoustic insulation also reduces heat gain or loss.
Does insulated ducting reduce noise?
Ducts work as a sound carrying channel, spreading sound from one room to another. The insulation you use outside the duct helps to reduce the amount of sound breaking through the duct wall.
What is duct board?
Duct board is a semi-rigid fiberglass insulation material often used for residential or light commercial heating and cooling applications in lieu of metal duct.
Does Lowe’s sell duct board?
Duct Board Insulation at Lowes.com.
How do I choose a duct silencer?
Normally, the selection of a silencer is limited by the space available and allowable pressure drop. It should be recognized that for a given silencer, the pressure drop will increase as the square of the duct velocity. Thus, at lower system velocities, more insertion loss can be achieved at acceptable pressure drops.
How do duct silencers work?
Most types of HVAC silencers contain baffles—acoustic media made up of millions of air pockets. When sound waves hit these air pockets, the molecules are bashed together and the energy is turned from sound to heat. This effectively reduces noise but also creates a pressure drop in the airflow.
Why is forced air so loud?
This can be caused by a lack of return air, which can occur because too many vents are closed off, or furniture is obstructing airflow. It’s also possible a more significant issue exists—undersized or improperly installed ductwork.

What is a duct liner board?
Duct liner board delivers efficient sound absorption, low thermal conductivity and minimal air surface friction. Discover the fiberglass duct liner insulation solutions perfect for your commercial and industrial projects.
What is silentfiber duct liner?
The SilentFiber Duct Liner is fiberglass insulation, manufactured from fiberglass wool combined with a high-temperature resistant resin. This product is great at absorbing sound and is sold in rolls. SilentFiber Duct Liner is equipped with a sturdy, non-woven, fiberglass surface that is easily installed with steel hanging accessories.
What is the best soundproofing for HVAC ducts?
Vibra Block® can also be applied to the ductwork itself. Insulating ducts with a soundproof material will not only quiet the noise caused by HVAC systems and airflow, but it will also reduce your energy costs because it offers thermal protection.
Why are my HVAC ducts making noise?
If the ductwork has poor installation, parts may even move from the force of the air moving through them. Whether you hear wind-like sounds or vibrations, you need to find a means of quieting these noises. While HVAC ducts excel at transporting heated or cooled air, they also move sound throughout your home.
