You can install these after the ductwork is installed. It takes a little longer, but is designed with this in mind. The insulation has a natural seam - using sharp contractor shears you can cut the sleeve lengthwise along this seam. Then place the insulation over the duct and the sleeve over the insulation. You may wrap 1/2"-1" of the insulation over itself to minimize the air gap without compressing the fiberglass. I try to offset the seam in the insulation with the cut in the sleeve. Once the sleeve is generally in place use foil tape to secure both ends and the middle, then use long sections to seal the remainder of the seam. Read Less

I want the 4 inch sleeve for my 4 inch ductwork from the bathroom fan into my attic (the Maine winter is causing condensation to drip back into the house). I can't find it at anywhere.

Answer: 
It seems that you could use the 6" sleeve if you cut the sleeve down the seam, wrap the insulation over itself (without compressing it) and overlap the sleeve before taping it. It will take a bit longer, but should be doable. I used 6" sleeves on existing ductwork, and slightly wrapped the insulation over itself to reduce the air gap between the insulation and duct.

Customer Reviews

Rated 3.2 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by great service and Quality product great service and Quality produce. just as advertized July 5, 2016
Rated 5.0 out of 5.0 by Worked as planned Very easy to slide over 6 inch. duct , installation was quick and easy to work with. March 29, 2016
Rated 5.0 out of 5.0 by Works good for my needs Some bad reviews on this product... Idk why. Basically what you see in the bag is what you get. It worked well for my needs. I wouldn't want to do a whole house with it- but it would work. There is probably a better product if your doing a lot of insulating. I just needed to do one duct. Also- not the measurement on the package and the difference between radius and diameter. I got the wrong size but still used it. February 23, 2016
Rated 1.0 out of 5.0 by Absolutely inferior prooduct This is a total junk and a perfect example of a corporation cutting corners and shorting a consumer. Your get 2 separate pieces: one is fiberglass and the other is some very easy to tear foil-like material, which goes on exterior, the jacket. Both pieces are shorter then advertised. Now, in order to install 5 foot piece, you either need 3 people or a bunch of tape that can stick to fiberglass, because the manufacturer did not glue the two pieces together! So you working alone and wrap your duct with a fiberglass piece first, and used about 60 inch of foil tape to hold it in place! Now you wrap the second piece, the jacket over fiberglass and tape it again - say another 60 inch of expensive foil tape! And if you need to make cuts to get around joists, while draping these pieces over a duct, good luck to you! Total junk. December 20, 2015
Rated 4.0 out of 5.0 by Easy to install Installed these over existing ductwork in a tight crawl space.The outer shell is tough and the insulation stays together. It's important to user sharp contractor shears to cut the liner, and avoid jagged cuts. December 29, 2015
Rated 2.0 out of 5.0 by Awkward and tear prone When I used this two years ago, it consisted of a long rectangular batt of fiberglass insulation curled inside a silvered Mylar sleeve. The Mylar tended to tear and the batt tended to shift. I had better results with the more rugged foil backed product cut to fit and closed with hvac foil tape. September 10, 2015
Rated 4.0 out of 5.0 by Used on existing ductwork. Works great. I been using this for my existing in place 6 inch ductwork. Had to cut the foil wrap lengthwise. Thus laid the fiberglass first on the ductwork and the place the foil wrap on top of that. Like the other reviewer I used foil tape in short pieces to hold together the foil wrap at the ends and middle of pipe to keep it together until I can more fully seal the pipe length. Don't use the cloth duct tape, use the foil tape! Doing it this way made it faster to install but of course in older houses you will encounter the tips of the above flooring nails, which is what the foil wrap at times get caught on as you pull and align it along the pipe. Other than that it was easy to use. September 19, 2014
Rated 2.0 out of 5.0 by Much Needed, BUT They Will Short You! Master Flow is not consistent with product, they are using two different fiberglass mats, a thicker firmer yellow mat and a thinner less firm pink mat insulation! Secondly, the outer aluminumized shell is consistently shorter then the fiberglass mat, which is stupid because you want to overlap outer shell to tape ends together! Thirdly, as the description states "up to five feet" because it is not five feet, they short you up to a half a foot! If you wanted to put up three units, end to end, to reach 15 feet, you will never get there, and need to buy a forth unit! December 8, 2014
