Answer

If you have the correct static pressure from the source that is exhausting this would work. The key is to pull it straight with minimal bends. If you do have to make a turn dont make it so sharp that it restricts the airflow. Now depending on what you are exhausting this could be the wrong material to use. You should not be exhausting a dryer vent or kitchen stove hood exhaust which should be fire rated.

yes, that is what I used it for. Mine ran through the attic so the insulation helps prevent condensation during the winter.

Yes you can use it . No dont run it through the old . Replace the boots and use proper size. Look up you tube video installing flex supply duct. This is what they use in most Mobile home construction. You will need to strap it up so it doesn't lay in the dirt

Easy to work with. Does exactly what it is supposed to. I had two 25 ft sections. Used about 20 ft for one duct and attached the remaining 5 ft to the other full 25 ft section for a second needed duct. Had to stretch it a bit so as to not have to buy another 25 ft. Would have liked it if it came in greater than 25 ft sections - maybe 30 or 40 ft length.

Following an upstairs flood, I had to replace my air duct since a lot of water went down the old air duct. This duct, plus a couple of zip-ties made an easy job! To cut it, I used a box-cutter knife, plus a pair of wire cutters when I got to the coiled wire of the duct. If needed, a little extra silver/foil duct tape can help ensure it doesn't leak air around the seal, sort of a belt & suspenders approach to ensuring the duct doesn't slip off the zip-tie connections.

Excellent stuff it's a much better value than the more expensive similar models by other brands I actually didn't use for its intended use, I cut in half the long way and wrapped around steam pipes. It was 1/3 the price of official pipe insulation! 10" tube was perfect for 50' of 4" steam pipe, 8" tube was perfect for 50' of 3" steam pipe. The trick to getting it to fit nice without compressing the Rvalue from 6 to 4 was peeling in half from 1.5 to 0.75" and wrapping around gently twice (also why as shown in the photo the pink glass stayed on the pipe until I put on the silver foil) Alternatively you can cut into long strips 1/4 of the width and spiral around the pipe if you curl gently enough you can maintain the 1.5" of the R6.

With the freakishly cold weather we've been having this winter, we developed a problem with water vapor freezing inside our regular plastic ducting that connected the bathroom vent fan up through the attic and out through the roof. When the ice would melt, water would drip back out of the vent fan and make a mess in the bathroom. We removed the old plastic ducting (along with the 10 lb chunk of ice that was inside it - wow!) and replaced it with this. It was easy to connect since the inside is the same size as the regular cheapo plastic ducting. And since switching, we have not had any more dripping so I assume it is doing its job. The only problem is that 25 feet of this is WAY more than we needed and it didn't come in smaller lengths. So now we have a pile of leftovers which I suppose we'll use if any of our other bathroom fans have the same issue in the future. Anyhow, this did the job for a reasonable price and now we can sit on the toilet without getting dripped on - what more could you ask??
