6" Insulated Flexible Duct — R-4.2, 25 ft Length

Keep the Air You Paid to Condition — All the Way to the Room

Every foot of duct running through a hot attic or a cold crawlspace is a chance to lose the air you just spent money conditioning. This 6" flexible duct is wrapped in R-6 insulation and sealed in a foil vapor barrier jacket, so temperature stays where it belongs and condensation does not form on the outside of the run.

At 6", it is sized for trunk and equipment connections, the runs feeding your ERV or HRV before the system branches down to individual rooms. It ships as a 25 ft length, compressed for handling and ready to stretch out across the joists.

Key Features
