The Sunco Duct 5ZANT-40-25 is a CNC-manufactured insulated distribution box with a 400mm inlet and five independently controlled 250mm outlets.
Its precision-mitred body is manufactured from 21mm foil-faced PIR ductboard, delivering a calculated material rating of R0.95.
Comparable EPP products generally require approximately 40mm thickness to approach R1.0. Foamed rotomoulded LLDPE fittings may require approximately 25–35mm to reach R0.4, depending on foam density, consistency and verified thermal conductivity.
While R0.4 may satisfy minimum requirements in some applications, higher thermal resistance provides greater protection against surface condensation in Queensland’s hot, humid roof spaces—helping prevent coffee-coloured ceiling stains and costly callbacks.
Pair it with our Australian made 4-Zero R1.5 Flexible Duct for a high-performance thermal installation designed for Queensland conditions.
Custom spigot and motorised zone-outlet configurations are available in 200mm, 250mm and 300mm sizes. Hit us up and we can make it happen!
Fast Clip-In Installation
The ANT body fits through most larger return-air grille openings before its fittings are installed.
Each 250mm spigot and zone motor fits through a 250mm round-diffuser opening. Tape the flex to the fitting below the ceiling, pass it into the roof and clip it into the ANT box.

*Typical airflow assumes two ANT boxes connected to separate supply-air ducts. Thermal values are material calculations based on published conductivity figures; finished-system performance depends on correct sealing and installation.
