Rated 1.0 out of 5.0 by fuzzycarpenter Worst. Insulation. Ever
The label says this is 2 inches thick, R6. The thickness varies between 1/4" an 1/2". No, it does not expand at all like normal compressed fiberglass insulation. Leave it out for an hour or a month and it is the same thickness. Completely worthless. If you buy it, then just drop it into the garbage can on your way out of the store; save yourself a headache.

Rated 3.0 out of 5.0 by ESP Not as advertized
The reason I purchased this item was because of the advertisement that it improved air flow. I was required to remove the filter after a couple hours of operation because the air flow was decreased compared to a pleated filter.
Price was good. It just did not work in my application.

Rated 3.0 out of 5.0 by Lewis It is what it is
For the price, it could definitely be better. Other reviews are correct. The fiberglass is poor quality. It sheds lime crazy. The foil is thin. It tears easily. The fiberglass is however glued to the foil. Just not well. It worked for my application but not without care and a little bit of itching. There are not a lot of alternatives out there. I used it to insulate a dryer duct which runs through unheated space. It might work for you. Just be prepared for some headaches.

Sheds large fibers and foil separates quite easily. Wasted my money as roll is now unusable.

Rated 1.0 out of 5.0 by Madmac Buyer Beware
I agree with all of negative reviews on this product. It is flimsy and you will be inundated with fiberglass.
Comparing it with Flow Master products is night and day. I question if this product actually achieves the R Rating it claims, especially after comparing its quality Flow Master products. I will be returning 2 of the 3 packages of this product that I purchased.

Rated 4.0 out of 5.0 by hvacgeek Worked fine wrapping HVAC
I also do not understand all the negative reviews, this worked fine for me. Used it to wrap the HVAC in my basement util room as the duct work was was radiating out so much heat that the room was 90 degrees.
I only had problems with the metal backing falling on one end of the two rolls I bought. I also wrapped the seams with thick metal tape.
