What Is Acoustic Duct 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 the purpose of acoustic lining?

Specifically designed as an interior insulation material for sheet metal ducts used in heating, ventilating and air conditioning. Provides an optimum combination of efficient sound absorption, low thermal conductivity and minimal airstream surface friction.

What is acoustical lining?

A fiberglass blanket material used as a lining inside a sheet-metal duct of an air-conditioning system; reduces noise which is transmitted along the duct and provides thermal insulation.

What is duct liner used for?

Fiberglass internal duct liner is commonly used in many commercial heating, ventilation, and air conditioning (HVAC) system. Fiberglass duct liner provides sound attenuation by dampening noise from HVAC equipment, and sound from adjacent office spaces.

What is duct liner made of?

Duct Liner PM is a flexible duct liner insulation made from strong, glass fibers bonded with a thermosetting resin. The airstream surface is protected using a durable glass mat facing that contains an EPA-registered antimicrobial agent. The flexible glass mat also provides a smooth airstream surface.

How do acoustic liners work?

Acoustic liners are used for dissipation of aero-engine noise, for instance in the intake and bypass ducts of aircraft engines. Basically, conventional aircraft liners convert acoustic energy to turbulent fluid motion and thermal energy due to the induced periodic in and outflow as well as viscous effects.

What is duct silencer?

A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.

What is acoustic insulation material?

Sound insulation: prevents the transmission of noise by the introduction of a mass barrier. Common materials have high-density properties such as brick, concrete, and metal. Common sound absorption materials include open-cell foams and fiberglass.

What is the best acoustic insulation?

What type of insulation is used for ductwork?

The most common material used for insulating heating and cooling ducts is fiberglass. Fiberglass duct insulation is available in various thicknesses and R-values and in either a flexible or rigid form.

What is FRP duct?

Fiberglass Reinforced Plastic Duct is custom manufactured for Industrial Corrosion Resistant Fume Exhaust applications. The resin system used is determined by the chemical, pressure and temperature exposures that the duct is subjected to.

Are fiberglass ducts safe?

Fiberglass. When ducts are damaged or deteriorating, they can introduced particles of fiberglass into the air you breath. According to the American Lung Association– Inhaling fiberglass can reduce lung function and cause skin eye and throat irritation, in humans and animals.
