Product Overview

The Master Flow 6 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 and 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
  • Always install per instructions and seal using approved mastic or sealant (or approved tape)

Answer: 
Yes, ...well kinda.
if your doing new work and you have this product laying around (like i had) you can cut the piece to length, then carefully pull out the inner plastic duct, and slid the insulation over ridged ductwork. obviously not what its made for but works.

I suppose you could slide this over the existing duct, but you are going to have to cut this to fit around everywhere that your current ducting is supported. Keep in mind this duct has a wire form running through this to keep its form, so you would have to basically cut this product apart to remove the inner duct and just reusing the outer insulation.

Answer: 
Yes but you must get a pipe reducer to connect them together with. Using zip ties and mastic will make the job put together better and will stay together better without leakiage ! You will also need mesh strapping to hang the pipe up with.

Answer: 
It sounds like from your question you are looking to replace these two runs of ducting. If you are looking to replace 7" ducting with this then you aren't going to get as good of air flow through this due to the reduced size and the uneven internal surface of this product. I would look to go larger (8" or possibly even 10" if replacing rigid) rather than smaller.

Answer: 
That is what I bought and used this for. I would just make sure to run your ventilation fan for a little while after the shower or whatever is causing the vapor to dry out any condensation that may have formed on the inside of the ducting.

Answer: 
You should get the correct ducting for your stove top to avoid fire hazards and code violations. the home depot floor reps or pro desk manager should be able to help you. Also, you may save some money getting the correct stove ducting as HVAC ducting is expensive

Answer: 
Thank you for contacting MasterFlow ... Not recommended for use in this application. In case of a fire, the flexible duct could be a source of combustibility. A solid metal pipe is the product for this application. Check with your local building codes before any additions or modifications to your dwelling. Please call Technical Services at 800-211-9612 with any additional questions.

6 in. x 25 ft. Insulated Flexible Duct R6 Silver Jacket is rated 4.4 out of 5 by 50.
Rated 5 out of 5 by from Works very well and easy to install The ducting was very easy to install and had a minimum of internal corrugation after being fully elongated once. Nice snug fit over over duct boots and collars. Quality construction.

We ordered two boxes of duct and the first box was two feet short even when we stretched it out and another three feet of insulation was missing from one end of the ducting. The second box was okay though the duct was 6 inches short. Fortunately, we had enough to do the job. Decent quality ducting and a good price, though you may want to measure it if the length is critical.

I used this product for running a vent hose from a new exhaust fan in a bathroom. It was easy to work with and I liked the fact it was insulated so there shouldn't be any major condensation running back down into fan. Very flexible product. It is a pain to cut.
