Acoustic Ducting effectively reduces the noise produced by your fan/extraction system. It contains a layer of sound and heat insulating fibreglass meaning there is also less heat given off from the ducting. 

How does acoustic ducting work?

Acoustic ducting has an inner and outer layer of flexi-ducting, separated by a layer of insulating fibreglass in between them. As air travels through the ducting it causes the inner layer of the flexi-ducting to vibrate. This would normally create a humming noise. The insulating layer of fibreglass in the acoustic ducting prevents the vibration from getting from the inside layer of flexi-ducting to the outside layer of flexi-ducting. This reduces the hum from the duct vibration and dampens the sound of a ventilation fan.

How effective is acoustic duct?

We find this acoustic duct dampens the sound of fans by about 50%. Use this acoustic ducting along with a quality silenced fan and you can be 100% sure there will be barely a noise escaping the ventilation system.

Acoustic ducting tip

If you are cutting a length of fiberglass acoustic duct, wear some old clothes and gloves to protect from the insulation getting on you.
