Acoustic Insulated Ducting 25cm x 10m dampens the noise generated by fans. To achieve this, foam padding is added to the walls of the duct, with the added benefit of insulating heat that passes through extraction fans.

Acoustic Insulated Ducting very effectively helps reduce the noise produced by your extraction system. If you need to keep things quiet, acoustic ducting will help!

How Acoustic Insulated Ducting Works.

Acoustic Insulated Ducting consists of an inner layer and an outer layer of flexi-ducting separated by a layer of insulating fibreglass in-between.

As air passes down normal flexi-ducting, the sound of the fan and the flowing air vibrates the ducting producing noise.

The insulating layer of fibreglass in our acoustic ducting prevents the vibration from getting from the inside layer of flexi-ducting to the outside layer of flexi-ducting.

If the noise from your standard flexi-ducting is causing a problem, using acoustic ducting will help reduce it.

Please note: Acoustic Insulated Ducting will not stop your duct-fan itself from producing noise.

To help reduce the noise from your duct-fan, try installing it by hanging it from bungee cords.

Acoustic Insulated Ducting will also not completely silence the sound of the air coming out of the end, we stock a range of silencers which will help reduce this noise.

Air noise can be further reduced by creating swept bends rather than having sharp right-angles when going around corners and by stretching out the ducting as much as possible.

How to Use Acoustic Insulated Ducting.

Acoustic Insulated Ducting fits directly over the flange of your extractor fan or filter and an appropriately sized duct clip is usually used to hold it tightly in place.

The Acoustic Insulated Ducting can then be run to your air outlet/inlet.

Although Acoustic Insulated Ducting works fine when run loose, the noise coming out of the end of the ducting will be greatly reduced if it is stretched out as much as possible.

To reduce Acoustic Insulated Ducting down to the correct length, use a sharp pair of scissors to cut the aluminium and fibreglass and a pair of sharp wire cutters to snip the spiral wires in the appropriate place.

This Ducting is manufactured to 254mm to ensure it fits over all 250mm standard air duct fittings, fans & filters.
