Flexible Ductwork
Flex duct makes adding air duct runs easy and affordable. No need to wrap with insulation because it already is.
Simply slide over round metal fittings and fasten to create complete air runs for new installation or repair.

We carry 25' runs of R6 and R8 insulated flex duct in the following diameters: 4" 5" 6" 7" 8" 9" 10" 12" 14" 16" 18" 20".

Each section of flex duct is compressed and bagged for easy handling and shipping.
When you're ready to install just open the bag and stretch to the desired length. Flexible ducting is easy to cut and maintains its shape through long radius turns.
Can also be compressed on the ends to fit oval connections.
