Product details:

EcoFoil "Big 8" HVAC Duct Insulation Wrap (R-8) is specifically designed to reduce radiant heat gain and loss in residential and commercial duct applications. This insulation wrap also helps control condensation by providing an airtight thermal break around the HVAC ducting. Important - All seams must be taped so the insulation acts as a vapor barrier. We recommend taping the seams of the HVAC duct insulation with EcoFoil Premium High Tack HVAC Tape, so the product acts as one continuous sheet.

"Big 8"duct insulation is constructed of a triple layer of polyethylene single bubble insulation, with each layer of single bubble insulation bonded to two radiant barrier metalized sheets. The insulation is (9/16" to 5/8") thick with a large single bubble insulation in the center, sandwiched by two thin layers of single bubble insulation. Each roll of insulation duct wrap includes two rolls of spacer strips. In order to achieve the R-8 value the spacer strips must be used and placed every 2' on the ducting. This provides an additional air chamber for the insulation. When combined with the spacer strips the finished thickness is 11/16" to 3/4" thick.

EcoFoil R-8 HVAC Duct Insulation Wrap is meant to be used around any duct work in your home or building. This includes round, rectangular or square ducting. It is NOT rated for exterior use. For installation or technical questions, please call our product specialists at (888) 349-3645 or reference our ductwork insulation page.

Excellent for heating and cooling!

This completely exceeded our expectations. We have a new house with a partial crawl space and a half basement built during COVID. This product was only used on ductwork below the joists in the crawl, everything between the joists was insulated with Rockwool.

The very worst duct in our home was in the second floor loft. In summer it would be 8 degrees warmer than the best ducts and in winter it would be 6 degrees colder despite the fact that it only had 16 feet of uninsulated run from the main supply trunk.

After double checking all of the ductwork the installer had missed sealing the corners of the metal ducts. Doing that brought the temperature difference down to 4 degrees in the summer. After using the foil insulation this duct became the coldest in the entire house during the summer and the warmest now that we are using the heat. It's taking me a while to complete this as I want everything just perfect. I'm redoubling my efforts to get this finished before winter as it's made the house way more comfortable already.

It does reduce the noise noticably as well. Before using it we could hear the HVAC over the TV whenever it would kick on. Now we have to mute the TV to see it it is running. Oddly it also reduced other noises in the house like the dryer and refrigerator. The main HVAC supply and return trunk lines run underneath those so I suspect the noise was echoing through the ductwork.

I looked all over before settling on this product and it has made a huge difference in the comfort level of the house.

    Frequently Asked Questions

    What is the R-value of this product?

    When installed properly, this product has an R-value of 8. Make sure to tape all seams with Premium High Tack HVAC Tape, and use spacer strips (included) to provide an air space between the ductwork and the insulation wrap. You can learn more about installing HVAC Ductwork Insulation here.

    Does this product meet code requirements?

    Yes, as long as the seams are taped and spacer strips (included) are used. As a bonus, it's stamped and certified with an inspector-friendly code strip attached directly to the material which makes for quick approval.

    Are special tools required to install this product?

    No. This product is cut easily with scissors or a sharp utility knife. Please note: all seams must be taped to prevent passage of air. Depending on the height of your duct, a step ladder may also come in handy. You can learn more about installing HVAC Ductwork Insulation here.

    What does the spacer strip do?

    The included spacer strips provide an extra air chamber between the ductwork and the radiant barrier. This reduces contact between the surfaces, preventing heat gain/loss and reducing buildup of condensation.

    Can I install this product outdoors?

    This product is not rated for exterior use. We do not recommend installing this product in outdoor applications.
