CUSTOMER REVIEWS

Rated 2.9 out of 5 by 14 reviewers.
Rated 4.0 out of 5.0 by This is a great product I used 15 rolls of this duct insulation - the 6 and 8 inch - to repair existing ductwork in a very confined crawl space in my 40 YO house. That meant the insulation wrap had to be cut. Here, it is important to have very sharp scissors to prevent snagging and tearing. Other than that, it was very easy even in the limited work space. After cutting the wrap lengthwise, the insulation was laid over the duct, then the wrap was laid over and pulled onto place. Using flexduct tape, put 3 strips - one at each end and one in the middle to make a temporary hold Then ran tape the length of the seam. Simple as that. Installation on new ducts would be even easier since no cutting would be required. The insulation quality is very good and the outer wrap is strong yet very flexible. I highly recommend this for anyone to use and the price was very reasonable. This was my first try at doing the ducts and, for just a diy-er, it went very well. May 6, 2009
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
Rated 2.0 out of 5.0 by Best for new or disassembled venting I agree with the previous comments regarding trying to cut and tape this over existing ducting. It probably works pretty well if you can just slide it over a piece of duct before assembly. For retrofit work, I'd suggest buying foil backed batting and cutting to size instead. May 26, 2013
Rated 4.0 out of 5.0 by Good Stuff This sleeve insulation was installed around existing heating ducts that are located in an external crawl space. There was low clearance under the CS so the sleeves were cut lengthwise outside the CS, drug underneath w/ sleeve insulation lying on top of sleeve's vinyl cover, then wrapped around duct sections and taped w/ aluminum duct foil tape. The sleeves and insulation held up well and did not tear or snag on the ground in spite of rough treatment before installing. The sleeves were designed w/ ample vinyl covering and insulation to be easily wrapped around the circumference of existing ductwork. The vinyl cover was mildly stretched and overlapped before sealing w/ tape and vinyl did not tear. The sleeves were reasonably priced. I haven't checked the sleeves since installing so have no opinion how they are holding up. December 10, 2014
Rated 4.0 out of 5.0 by Foil was a little short The. Foil that goes over the insulation was insufficient to cover the insulation itself. March 5, 2013
Rated 1.0 out of 5.0 by Just save your money and buy a roll of insulation For about 3 feet of insulation, the cost does not justify the spend. True ...it's a small package. And easy to handle. But not good value. February 18, 2014
Rated 2.0 out of 5.0 by Don't do this alone This product comprises a 6' long tube of aluminum foil, surrounding a sheet of fiberglass wool. To fit to new ducts, you pull the tube over the duct and tape into place prior to installation. I was in the position of having to fit to existing ducts. Instructions tell you to first secure the foil to the fiberglass with tape, then split the aluminum cover lengthwise; the fiberglass is already split so you're forming a two-layered sheet. Wrap this sheet around the duct and tape it closed. In practice, I found this to be immensely difficult and frustrating. Does adhesive tape stick to fiberglass wool? Not hardly, so the foil and fiberglass keep coming apart and going separate ways. Like in 99% of houses, my duct-work is in awkward, hard to get at places, so I was at screaming point in no time at all. My options; 1. wait until I have at least one other pair of hands to help, 2.disassemble the ducts and treat as a new installation, keeping the foil wrapper intact, or 3. return the three unused packets for refund. I'll probably go with #1, but I wish I'd known that fitting to existing ducts is NOT a one-person job before buying the product. December 7, 2011
