The Master Flow 14 in. x 25 ft. Insulated Flexible Duct R6 Silver Jacket is used in standard Heating and Air Conditioning (HVAC) systems and some venting applications. The duct has R6 insulation which contains 33% more insulation than the standard R4.2 product. This additional insulation provides greater thermal efficiency to save energy. The product is also covered in a heavy duty, silver jacket for durability. The duct is ETL listed, meeting the UL181 standard.

  • R6 fiberglass insulation for greater insulating power
  • Flexible duct is convenient for use in multiple applications including heating & A/C systems and some venting
  • Oversized core to connect quickly and easily to standard sheet metal fitting
  • Galvanized core wire for greater corrosion resistance vs. non-galvanized wire
  • Duct can be cut to length as needed
  • Insulated duct features a maximum temperature rating of 200 degrees Fahrenheit
  • Always install per instructions and seal using approved mastic or sealant (or approved tape)

Rated 4.9 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by excitement plus! I was so excited when I finally received my insulated ducting because it meant I finally had an excuse to crawl around a roof space during summer in Florida & hug fibreglass insulation! Seriously- the ducting is exactly as described. I replaced old ducting and now the AC actually cools the house properly (as I mentioned before, I'm in Florida so the AC works hard) October 21, 2014
Rated 5.0 out of 5.0 by 14" duct This was hard to find locally. Price was right, shipping was free, item was as described. Plus, I used PayPal. That was handy! October 28, 2014
Rated 5.0 out of 5.0 by flexible Insulated Duct The shipping packaging was great (it is compressed in order to fit into a reasonably-sized shipping container). September 30, 2014
Rated 5.0 out of 5.0 by Great purchase. It arrived before delivery date, by several days. I am extremely satisfied with HD delivery. The duct fit perfect. August 12, 2014
Rated 5.0 out of 5.0 by best price and quality product not in all stores, had to wait on shipping to finish the project. easy to install without any major problems February 26, 2013
Rated 4.0 out of 5.0 by Good Product Fast delivery. This is a high quality duct. It worked well in my application. It's important to make sure you have just the right size. December 11, 2012
Rated 5.0 out of 5.0 by easy to work with pulling and hanging new ducts couldn't have been easier. outside covering is tear resistant and can be pulled through tight spaces with ease. a bit difficult to roll back the insulation for connection to register boxes and take offs, but after the first one, I knew what to expect. and they look nice if exposed.............

Rated 5.0 out of 5.0 by Couldn't find anywhere else. Great price, too! My trailer uses only the 14". Not sold in stores - at least all the ones in my area (NOVA). Ordered online; showed up soon at my door; great price; worked great! Would get it from here again if I needed it. Thanks!! April 23, 2012
