john: I like the product with the exception of how it wraps around bends in my vent pipe. The foil backing should be more pliable to allow the wrap to follow elbows in the duct work. As it is, coverage in the corners is so-so and duct tape or similar has to be used to hold the material in place. Try to force it too much and the product tears.

Shawn L: It does what it’s suppose to do, wrap pipe and keep it insulated

D.M.: I got this to insulate my sourdough fermenting box. It’s working fine but I must have had the end of the roll. As I unrolled the material, 4 to 5 inches of the cotton insulation ripped because it was glued to the shiny side, made a mess. It didn’t leave much to work with. I had barely enough when in fact I should have had quite a bit left over. As someone commented, it is far from the 1 inch it is supposed to be. Not very good value I’d say.

Jared: TL;DR: Product comes very compressed to about 1/4 inch thickness out of the box reducing its effectiveness. It needs to be "fluffed" with some time and effort by you, the customer, to achieve the R Value of 4 at 1 inch of thickness (what the specs are listed as).

My biggest problem with this product is, as others have mentioned, the thickness the insulation comes in out of the packaging. Because it arrives in a tightly wrapped roll, when taken out of the packaging and laid out flat, the thickness of the insulation averages about 1/4 inch. The packaging lists the thickness as "1 inch", but clearly it is not.

Why should you care? The effective "R Value" of the insulation decreases (it becomes a less efficient insulator) as the material is compressed. So you're not getting the full insulating performance of this material the way it comes out of the package, and the packaging makes no mention of needing to "fluff" out this stuff. I doubt it would fluff up enough over time on its own to reach the stated specs, but I don't know for certain.

So how can this be fixed? Here's what I did:

1. Turn on some mindless television and get comfy
2. Take the product...

SeanCeltiad: I got this to use for wrapping my water pipes against freezing, the rolled narrow width pipe insulation is a pain to work with but with this I'm cutting it by unrolling just enough to cut across the roll side to side into about 4"x15" strips and wrapping the pipe so that the 15" is lengthwise along the pipe and the 4" is wrapped around, secure it to pipe with 2 or 3 small pieces of the aluminum tape to hold, then 3 more strips to hold it after you wrap it around to meet together slightly overwrapped, then use one long 15" strip of the aluminum tape to seal that over lapped edge against moisture and mice who love the insulation. It's much easier to wrap pipes this way, more economical imo and looks neat when done, also the foil backing on this is thicker than the rolled stuff, much thicker! I'm also thinking of using this to repair the damage done by rats to my engine hood insulation mainly due to the thickness of the aluminum, I had used some from the online auto store JCW prior to getting this and the aluminum on that was pathetically thin in comparison. Whether you plan on wrapping ducts or using it for other things where you need insulation, you will be happy with this product....
