Store SKU # 394317

Store SO SKU # 755578

The Master Flow 4 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.

  • 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
  • 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)

CUSTOMER REVIEWS

Rated 4.9 out of 5 by 22 reviewers.
Rated 5 out of 5 by good deal This 25' insulated duct was really a cheaper buy than uninsulated ducts, especially for the length as I could not find 25' uninsulated. And I needed every bit of that 25 feet. December 10, 2013
Rated 5 out of 5 by Good for bathroom vent fans I bought this after seeing a like-product used on This Old House to create a roof vent for bathroom fans. It works great and is easy to use/cut. This duct is compressed inside the box when you buy it, so be ready for it to continually "ooze" out of the box when you first open it. I only wish the Home Depot site had worked better, because it said the product was not carried in my local store, when in fact, it was. I happened to go down the ducting aisle a week after I bought this online and paid for shipping, and there were plenty of boxes of the ducting available in-store. May 28, 2011
Rated 5 out of 5 by great Great product. Easy to work with. Priced competitively. September 23, 2014
Rated 5 out of 5 by What you need for bathroom exhaust fans! If you are going to install a bathroom exhaust fan, or already have one, then this is what you need for properly venting it up and out of your roof. The insulation helps reduce condensation inside the vent duct in wintertime. In this box, you will probably get much more than you actually need, so it's a good value for the price. June 22, 2010
Rated 5 out of 5 by 4" hose This hose worked verry well. I used it to replace a metal duct to muffle fan noise. I now can barely hear the fan. December 11, 2010
