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

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.

Foil was a little thin, but this product works OK.

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.

Rated 1.0 out of 5.0 by roscoguy Terrible product!
What JUNK! The fiberglass is so fragile that by the time I had finished wrapping the duct there was yellow 'snow' covering everything! I ended up completely taping the seams (and tears) in order to stop it from falling. The foil covering was also very easily damaged and had torn edges right out of the bag.
STAY AWAY!! If you use this, you'll be cleaning up or breathing tiny, broken glass fibers for a long time to come.There have to be MUCH better products! This garbage doesn't even deserve the 1 star I was required to give it.

Rated 1.0 out of 5.0 by GMan Difficult to work with...
Bought this to wrap my rigid dryer vent to keep condensation forming.... will probably work for this but it was extremely difficult to work with. Foil tears easily, does not stay attached to the insulation well at all. Yellow fibers from the glass are extremely annoying, even using long sleaves and gloves. Have a shop vac ready, you will have lots of yellow fibers to clean up! Thankful that my vent is only 8 ft. long. If I knew before I started the project, I would have looked for a different product.

Unless your duct work has a ton of open space around it, good luck! Tears apart too easily and showers you in fiberglass powder. Really frustrating. I'll be looking for foam or bubble wrap style insulation for the rest of my ducts.
