THE Best Product On The Market For HVAC Duck Insulating
This is a terrific product that does just exactly what it was designed to do! I used it to wrap the HVAC supply runs in my older home and what a difference it has made! Very easy to work with. But just like any project, make sure you know what you are doing. Long sleeves, light gloves, a hat and even a face mask helps because the insulator in this product is fiberglass and it can shed in the installation process. That is to be expected. I think you would be very hard put to find a better product for it's intended use.

Worked well and quality was good
Worked well for insulating bathroom exhaust tubing. No issues other than it does shed lots of fiberglass partials so wear a mask for overhead work.

A bit difficult to work with.
First, the facts. The backing is not foil, it’s Mylar. The backing separates from the fiberglass quite easily. It’s made in China. Use with extreme care! Having said all that, I did get my project, covering the outgoing air manifold on the furnace, completed. However it took lots of time and tape to do it. So, three stars from me.

Good for Length Dryer Vent
I have a 15 foot dryer vent pipe from the laundry room through the attic roof. Unfortunately, no want to vent from the wall or shorter distance. The Insulation raps nicely around 4" dryer pipe and significantly reduces lint build up from cold exposure in the attic. Plus reduces dryer time.

Great product to insulate HVAC ducts.
Product worked as advertised and easy to put on, assuming you can get access to the pipes. Easy to cut when needed. I covered some 90 degree bends with success— just used some metal HVAC tape to secure the pipe insulation. I didn’t use gloves to protect my hands from the insulation material, but probably should have. Ordered a second roll to do some other pipes as well.

Their statement that it is self-adhering is a BOLD FACED LIE!!! 2" thick? Fugget about it! An inch is more like it. So you'd best arm your self with a roll of duct tape. I used most of the package with very little left over insulating a 5" round duct with 2 90 degree elbows totalling 6 feet of duct. Be carefull handling the foil facing too because it is barely attached.

L'espace est restreint. Tape métalique comme pour sécheuse. chaleur.
