How do I make my HVAC return quieter?
High static pressure makes airflow more audible
- Adjust the fan speed. Your blower or furnace fan should be set to deliver the proper airflow per ton.
- Add ductwork.
- Add a bypass duct.
- Add or expand grilles and registers.
- Replace existing registers and grilles with high velocity models.
What is acoustic duct liner?
What is it? 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.
Is duct liner flammable?
Duct Liner Adhesives Adhesives are classified according to their flammability in both wet and dry states.
How thick is r8 Ductline?
This provides an additional air chamber for the insulation. When combined with the spacer strips the finished thickness is 11/16″ to 3/4″ thick. EcoFoil R-8 HVAC Duct Wrap Insulation is meant to be used around any ductwork in your home or building. This includes round, rectangular, or square ducting.
Why is my return vent humming?
All air vents, meaning supply registers, ceiling diffusers, floor vents, and return grilles make some noise when the system fan is running. This usually, not always, but usually, indicates a lack of return air. The system needs to pull more air so the pressure and velocity increases, thus increasing the sound level.
Where should a duct silencer be placed?
The duct silencers are designed mainly to attenuate noises in ventilation ducting. In most cases, they are mounted between the fan and the diffusing or exhaust fan and before the air diffusers. Duct silencers should be installed behind fans, flow regulators.
How long does duct liner last?
Ducts are designed to last for about 10-15 years on average. They are made from a combination of materials such as fiberglass and plastic. At some point, these ducts will get damaged.
How good is R8 insulation?
R8 ducting uses thicker insulation than R6 ducting. This means that if you were to do air conditioning installation using R8 ducting, you get better insulation than if you are using R6 ducting. When it comes to efficiency of heat insulation R6 ducting is less efficient than R8 ducting.

What is quiet natural fiber liner?
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.
What is audio seal used for in HVAC?
AudioSeal® lag and wrap are used to wrap pipes and duct work to block the transmission of sound into and out of the system. Duct silencers, flat acoustic foam and plenum return silencers are used to help decrease the amount of sound or noise that may travel through the open channels in an HVAC system.
What is HVAC noise control material?
HVAC (Heating, Ventilation and Air Conditioning) noise control materials can help reduce the transmission of sound and noise through these systems.
