AC Infinity Flexible 12-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust

This is going to work beautifully. Haven't installed yet but is a quality constructed product.

This is super high quality duct work material, inside is foil and there are more layers, than the outside which is rubberized and tough. Would definitely buy again and recommend to others. I am using with their same brand whole house fan, exactly what we needed.

I've used a lot of different ducting over the years for various projects, this is one of the higher quality, if not highest quality ducts I've used. Its expensive but worth it. It doesnt feel like its piece of tissue paper, and can handle a decent amount of abuse, at least as far as flexible ducting it concerned.

First thing first, the build is solid, and it seems to insulate well. It fit great and can in some really cool packaging. HOWEVER, I am returning this because the ends of the tube don’t have a clear space for putting in the ring tighteners. The ends are simply just cut, which means you have the spiral wiring going all the way to the end, which your ring tightener will have to go over, thus not a proper seal. If you are a stickler for having flawless insulation on the ends, I would probably get something else.

Best duct I’ve ever seen, & I had a home repair business for 27 years. Super coated, & durable. I wish my whole house had it-

Seemed like a nice product. Hard to know how it will hold up in an attic over time. But it seemed much nicer than your typical Home Depot kit.

This venting was super easy to use. It pulls open a little easier than the other venting I've used yet is solid. I originally purchased this for the black outside as everything local is the regular shiny silver. It's exactly what I needed and I have already recommended it to others.

Nice, used for whole house humidifier install. Looks good and way better than hard to work with aluminum from HD.
