Install Fabric Air Duct Tips

Fabric ducts can generally be installed in 60-80% of the time required to install an equivalent metal system.

Decide which suspension system you should use. There are two main types: aluminum track or tension cables. Aluminum track is used where aesthetics are important. Cable system is used when cost is more of a concern, as it is slightly cheaper.

Figure out support the suspension system. Because fabric ducts are light weighted, anchorage points to the ceiling can be spaced apart by up to 2.5m (8'). The aluminum track can be supported using wires, or by threaded rods. Clips are usually supplied by manufacturer to attach the wire/rod to the tracks.

Mount the suspension rod/wire to the ceiling at intervals between 1000 and 2500mm (3' to 8').

Screw the SafeTrack clips onto the threaded rod.

Clip the safetrack onto the clips.

Slide the individual duct sections along the track from one end.

Zip each 5m section of duct together with zippers.

Once all the ducts are slid into place, secure the duct to the supply spigot using a strangle-band.

Turn the air handler on and the installation is complete.

Similar process can be used to install cable based suspension system. Note that the cables are tensioned to avoid sagging in the middle. The mounting brackets for the cables should have enough strength to stand the cable tension. Refer to the manufacturer's suggestion on their installation manual.
