Flexible Foil Duct 3m x 150mm
The flexible foil duct is a 3m length of 150mm diameter ducting for connecting a roof vent, exhaust fan or inline fan to its outlet. It is the shorter option in the range, which makes it the right pick for a single vent connection where a 6m run would leave a lot of waste. The aluminium foil construction is lightweight, flexible and resistant to heat, moisture and corrosion, so it holds up inside the roof space.
Key Features
- 3m length for a single vent or fan connection
- 150mm diameter for standard roof vents and fans
- Aluminium foil construction resists heat, moisture and corrosion
- Flexible corrugated body routes around obstructions
- Lightweight, easy to handle and trim on site

Specifications
- Length: 3m
- Diameter: 150mm
- Material: aluminium foil
- Construction: flexible, corrugated
- Applications: roof vents, exhaust fans, inline fans, outlets
- Installation: cut with snips, seal with duct tape or clamp
Installation
Cut the duct to the length you need with snips, leaving a little slack at each connection. Slide it over the fan or vent spigot, seal the joint with duct tape and secure it with a clamp. The flexible body bends around rafters and ceiling obstructions, so it routes through tight spaces without extra fittings or joins.
Applications
- Connecting roof exhaust vents to fans or outlets
- Bathroom and laundry exhaust systems
- Rangehood discharge through the roof or eave
- Airflow in attics, ceilings and roof cavities
What You Need To Complete The Job
Match the duct to the vent it connects to. Pair it with a static roof valve for a roof termination, or use the longer 6m flexible foil duct for a run that needs more reach. Browse the Roof Ventilation range for the full selection.
Frequently Asked Questions
How is this different from the 6m duct?
It is the same 150mm ducting in a 3m length. The shorter run suits a single vent or fan connection where a 6m length would mean cutting off most of the roll.
What can I connect it to?
It connects to roof vents, exhaust fans, inline fans and outlets with a 150mm spigot. The flexible body lets it route around obstructions in the roof space or ceiling cavity.
Is the foil construction durable?
Yes. The aluminium foil resists heat, moisture and corrosion, which is what a duct needs inside a roof space. The corrugated body also keeps it flexible without collapsing.
How do I fix it to a fan or vent?
Slide the cuff over the spigot, seal the joint with duct tape and secure it with a clamp. For a long horizontal run, support the duct every 1.5m so it does not sag.
Can I cut the duct to a shorter length?
Yes. Cut it with tin snips or a sharp knife and trim it square so the joint seals cleanly over the spigot. Cutting is straightforward because the duct is a flexible corrugated body, and there is no rigid lining to fight through.
