Works as described. Great for bathroom exhaust fan venting through attic space that isn’t conditioned (air/heat) to avoid condensation. The gloves where an added bonus.

Worked fine. Insulation was nice, felt pretty heavy. The box store wanted $20 more and I could wait a couple days.If I do anymore projects I'm coming back

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.

Just not the best quality. Very cheap rips easy. Not what I wanted and it smelled most likely some type of additive or spray. Just a terrible smell. Could not put that in a HVAC system
