Aluminium Foil Flex (Uninsulated) – 10m Long

Uninsulated aluminium foil flexible ducting in 10m lengths, stocked in 16 diameters from 3 inch to 20 inch. This is the workhorse flexible duct of ventilation installation: light, inexpensive, easy to cut with a knife and snips, and quick to clamp onto any round spigot.

Where plain foil flex fits

Use it for the short flexible connections every system needs — fan to rigid duct, plenum to grille box, valve tails, and the last awkward metre where rigid duct will not line up. A 10m length goes a long way when most connections use less than a metre. Keep runs short and taut for the best airflow: foil flex is a connector, not a substitute for long runs of rigid spiral duct.

If the duct passes through a cold loft or void carrying warm moist air, spend the extra on the insulated version and avoid condensation problems later. Diameters stocked: 80, 100, 125, 150, 160, 180, 200, 224, 250, 280, 300, 315, 355, 400, 450 and 20 inch, secured with hose clips. Stocked sizes despatch next day when ordered by 3pm.
