Huge improvement over regular duct
By Morgan C. on Reviewed in the United States on July 14, 2024
Purchased for a portable AC exhaust hose replacement. Works GREAT! Gets barely warm to the touch, when the old exhaust hose was extremely hot and radiating heat back into the room. AC is a little quieter too. Can't recommend this insulated duct highly enough, I can't believe I had been undermining my AC's efficiency for years with a non-insulated exhaust duct. The duct itself feels very well-made, each end has a short length of reinforced foil which fits under the included hose clamps perfectly. Insulated outer duct begins a few inches later, and the outer duct material feels very durable and flexible. The inner duct acts as the support and the outer duct holds the insulation in place, and the result is a dramatic drop in outer duct temp. AC has been running for a few hours now the outer duct is no hotter. I think we have a winner.

Inner liner is perforated
By Tom on Reviewed in the United States on September 29, 2024
This cannot be used as a moisture vent for a bathroom as the seller claims, as condensation will get between the inner tube and the outer tube in the insulation, and will not likely exit before making a hell of a mold population. From what I understand they make it this way so sound waves enter the insulation, but it really should have a disclaimer that this is not for high moisture applications.
