Rated 5.0 out of 5.0 by JBrock Best duct insulation!
We spent 3 days in a cramped (though dry and bug-free) crawlspace checking the alignment and connection of our air ducts. This insulation was easy to handle and easy for us to cut, wrap, and tape while on our backs or sitting hunched over. The fiberglass did NOT shred or flake as it did with the Frost King brand. Master Flow is the only brand we'll ever use again.

Rated 5.0 out of 5.0 by TheHandyMan Great for Garage dorr insulation
I just used this wonderful material to insulate my two door garage door. My objective was to make it cooler in the hot Florida summers but it turns out that it is warmer in the cooler nights also. An additional benefit is that it made a noticeable noise reduction with the function or the garage door.
Easy to work with, inexpensive and very functional. I will be looking for "other applications" for this product. I would highly recommend this product!

It was not what I expected from the picture. I mistakenly ordered this thinking it was plastic bubble roll. It is aluminum lined pink insulation.

Rated 5.0 out of 5.0 by RickU Helped cleanup a poor installation job
I had Home Depot install a Mistubishi mini split heat pump in my home. They did a horrible job, it took almost 6 months and several attempts before it finally passed inspection (I hear that many never do).
After the installation was finalized, I used this product to cover up the horrible bubble-wrap insulation they used when they installed it. It worked great for this use.

Rated 5.0 out of 5.0 by HandyMan Very Tough
Insulation is very durable and withstands tugging and pulling without ripping. I installed it by myself in a small crawl space so it wasn't the easiest job but is possible. Just be patient. Get good tape to seal it up. Waiting to see how much it helps once it gets really cold. Seems like the air is a little warmer.

Rated 5.0 out of 5.0 by Chris Best product for 6" duct
Insulated all the ducts in my crawl space. Tried several different products and Master flow duct wrap was the easiest to work with and looks the most professional when installed. Started with frost king, which was pricy, very itchy and did not have foil tab like Master flow. Tried duct sleeves which worked good but needed to unscrew the duct to put them on which was a pain. Master flow fit perfect around my 6" ducts and the foil tab lined up nice and made it easy to tape up. I would use anything else.
