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.

R-8 Duct Wrap

Easy to cut and size. Duct tape is a bit tricky to cut and takes a little practice. Overall much easier to use in a crawl space than fiberglass. I learned to wrap the ductwork a little loose to leave more room for air space. Order a little more tape than you think you need. Great customer service!!!

Light weight - easy to work with

Having never put insulation on HVAC ducts before, I wasn't sure if I could do it by myself. After watching a few YouTube videos on the process, it was easy to cut and fairly easy to wrap around the ducts. The video on making the appropriate cuts on the insulation to more easily wrap the angles and joints was particularly helpful. The R-8 insulation has only been on the ducts for a few weeks so not sure if the product will actually help lower my heating/cooling bill.
