Ducting is used with fans to carry the air from one place and expell it elsewhere, usually outside the building. Ducting comes in different sizes depending on the fan inlet / size. It can be used for Bathroom Fans, Range Hoods, Ceiling Exhaust Fans and more. We stock the standard Core Flex duct. However if you require Insulated Flex, Heavy Duty Flex or Semi Rigid Flex duct please contact us for pricing and availability. If there is a size you require which is not listed here, please contact us.
