Gorilla Acoustic 10m Ducting - 127mm (5 inch) CL

Acoustic Ducting A high quality, flexible aluminium ducting with a perforated inner layer and an acoustically transparent plastic layer to encapsulate the fibreglass. The noise reducing insulation limits break-out noise from the duct and acts as a fan silencer. For best results use on both the input and output sides of your extractor fan.
