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!

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.

This duct insulation is satisfactory to work with. Less shedding than I expected.

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 4.0 out of 5.0 by Diyguy Probably not rated for vapor barrier applications
In the short run, up to a few years, the foil side would definitely be a vapor barrier. But I don't think it is rated or tested for that application. So I would NOT use it for that purpose unless I could find supporting documentation from the manufacturer or another authortative source.
But as an insulator and radiant barrier, I really like it!

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.

Rated 5.0 out of 5.0 by EH Great product
I know it is supposed to be used to insulate pipes and ducts in the attic. I bought it to insulate the floor of a 1956 Chevy Belair works great. Other products cost two to three times as much to install the self stick is a plus. They need to advertise and sell as vehicle insulation as well, holds up great.
