    I bought this item to replace my old one. Dogs tore my old one apart. I was surprised at how long this was and the thickness of the insulation.
    Installation was a breeze. Extremely easy to find in the store and the box was smaller than expected (about 4’x18″).

    I used the insulated poly flex duct in my own attic. Its tough enough to resist tearing while pulling through and dragging over fresh cut holes in wood floor and joists. Rough holes in ceiling plaster did not tear or otherwise compromise the materials integrity

  3. DuctDuctGo

    Just as it is advertised, this is fairly easy to use; you should be aware that the insulation does add a couple of inches to the working diameter. You’ll want a good set of shears/scissors and pair of wire cutters to cut it, as well as the zip ties and thermal tape to secure and seal the ends. It is also packed into the box pretty tightly, if don’t use a significant length, it’s hard to repack the leftover.

    We were so glad to find this product in stock. I do wish that you carried 14” as well. It was easy to work with and it saved us a service call which would have been costly.

  5. Ceecee

    Our son installed new duct work for us using these. We couldn’t believe the amount of stuff that was in the old duct work. These worked great. We can breathe again.

  6. RanMan

    Cost more than the local HVAC Supply House. The duct is not fiber re-enforced like the ducts from the supply house. There is a nation wide shortage on flex duct, so had to use the lower quality material to complete the job. This is for my personal home, so we will see how it holds up long term. The plastic is very durable and does not easily puncture.
