Why insulate your ducts with HVAC bubble insulation?

Insulating your HVAC ductwork with radiant barrier can improve energy efficiency, enhance comfort, reduce noise levels, improve air quality, and extend the lifespan of your HVAC system. By reducing heat loss or gain through your ductwork, radiant barrier insulation can help maintain a consistent temperature throughout your home, while also preventing mold growth and reducing energy bills.

I'm always impressed when my order arrives a day or two after placing the order. Amazon Prime isn't even that good!

Excellent Product

This is my go to product for duct insulation. Most of my work has been in 50 year old houses, so the prep work is most of the job, cleaning and sealing the old sheet metal ducts. R-8 HVAC Duct Wrap insulation is the icing on the cake. I have noticed that side by side with other products outside in the sun, the reflection from this duct Wrap will blind you compared to the other products I have used in the past. It has translated into some impressive savings when comparing before and after heating and cooling bills.

Deeply buried ductwork

We're using the R-8 duct insulation for ventilation ductwork in our unconditioned attic. It will be buried in cellulose insulation. Insulating mainly to avoid condensation. Easy and clean to work with.

Easy to install & can tell difference in heat already

Impressive Results!

I had an installer install the wrap on my galvanized duct work in my crawlspace. Almost all of my original insulation sloughed off over time (1973 home) due to condensation and no vapor barrier in the space. I took readings with my infrared thermometer before and after install. My average temperature from the vents was raised 8.2 degrees! I should have done this 7 years ago when I bought the house.
