10 Inch Insulated Duct,10 inch Insulated Flexible Duct 25 Feet Long R-4.2,Insulation AC Flex Duct, for Heavy Duty HVAC & Exhaust Ductwork

Not much to say here: it’s 6" insulated flexible ducting, and it did the job perfectly. Easy to work with, solid insulation, and exactly what I needed for my project. Sometimes you just need something that works without any drama—and this delivered. Five stars!

The inner "foil" layer was much tougher than another reviewer said. It's more of a "mylar" plastic silver mirror kind of material. I only needed 15 to 17 feet, so I didn't mind ruining the end I attached to a rope for pulling through the hordes of black widows and rattlers. The insulation is as expected. I did tear the outer layer just a tiny bit pulling it with a rope I'd fish-taped through a confined crawlspace trench I had to hand-excavate. Attaching it firmly to the flanges worked well however the Hose Clamp, or Radiator Clamp style items supplied were some metric size I had no socket bit for. So, picture a guy on his back in dirt with spider webs hanging down trying to use a flathead driver on his drill to tighten a long long long clamp. One spider said: Hey, how-ya-doin?" I have patience. I attached it to one flange from inside the home, the other from underneath. Both ends were easier than expected. This is a quality product, but fragile as you might imagine. Be careful of it and it's tough enough and a good value.

WORKED GREAT

Seems like good quality did not use it yet

Works well and seems well built.

not quite 25ft, more like 23.5ft. Used these for two bathroom vents Wish the insulation was more robust, it's pretty thin. let's see if it'll work. the gloves in the picture is not what's in the box, the video claims they are cut resistant, but what arrives in the box are cheap cotton gloves.

Easy to use and cut, the length and size was as discribed

This product was very disappointing for two reasons. First, the inner aluminum foil duct was so thin and flimsy that it was impossible to get it onto the vent structure without tearing. I finally just wrapped aluminum tape around it to stiffen and reinforce it, and that worked marginally. Second, the duct clamps were not nearly long enough to wrap around the inner duct. They couldn't even wrap fully around the vent structure which is smaller than the duct! I had to use some other short clamps to attach to these to make them long enough to work. If I had not already cut the section of duct that I needed, I would have returned the whole mess. Don't waste your time on this junk!

Il tubo è molto resistente e lo consiglio vivamente....

Works great for outdoor ducting to a diesel heater

exactly as it satated, not much more one can say about it
