Hi-Velocity Flexible Duct can be installed quickly and easily, delivering the air quietly with a sound absorbing inner core. The inner core is made of a double lamination of foil laminate and clear polyester film which is interlaced with a galvanised steel wire (.041) having a 3/4” pitch.The core is wrapped with fibreglass insulation certified “GREENGUARD” having a coefficient of R4.2/R8.4 and is encapsulated by a metalized vapour barrier reinforced with fibreglass string. Our HE duct has been designed as a direct alternative for two 2” flex duct used in the Hi-Velocity System.
No changes are required to fancoil selection and main plenum duct sizing.
e.g. 1 - 10’ length of HE duct is the equivalent of TWO 2” -10’ flex lengths. The Perfect Choice for
