1.6. Flexible Duct
Securing Flexible Duct
Flexible duct must be installed with supports at maximum intervals of 1.5 metres. Flexible ductwork
can be supported by using gaffer or electrical tape. Provided that it does not restrict the internal
diameter of the ducting. Ducting installed looped over hanging beams should be installed in such
a manner as to ensure the changes of direction are gradual. Support of the ducting with the use of
hangers may be required, see option 2.
NOTE: Ducting should be kept taut at all times.
