The Acoustic Flexible Ducting are used extensively across the UK due to its noise reducing nature. It is made with an inner duct with a 25mm fibreglass insulation and is covered with an outer jacket, providing unmatched noise reduction. The jacket is a spirally produced multi-layer aluminium/polyester laminated fabric reinforced with fibreglass yarn, providing excellent strength and tear resistance. It is supplied in a standard 5 meter length, but can be compressed to 1.6 meters, with the option to be cut to a specified length (no special tools required for cutting or fixing). With it being flexible, it can be connected to either round or oval ducting with ease. Alongside this, they have been designed with quality at the forefront- they have been successfully tested and are fire resistance rated (M1), with no danger of toxic gases being emitted in the case of a fire.
