Ductwork Insulation

What is Bubble Wrap Duct Insulation?

HVAC bubble wrap is a convenient and effective solution for insulating ductwork. It’s made from a triple-layer construction of single bubble insulation, with each layer bonded to radiant barrier metalized foil. This design delivers an R-8 insulation value by reflecting both radiant and convective heat. It also helps prevent condensation and acts as an approved vapor barrier.

The Benefits of HVAC Bubble Wrap Insulation

One of the main benefits of HVAC bubble wrap is increased energy efficiency. While modern heating and cooling systems are designed for optimal performance, the ductwork that distributes the air often lacks proper insulation. Metal ducts provide little to no insulation value, and as air travels through them, energy can be lost through poorly sealed joints or heat transfer.

By combining R-8 duct insulation with a high-performance HVAC tape, you can improve duct sealing and reduce energy loss. This helps maintain consistent air temperatures during transport, especially on longer duct runs. The result is improved HVAC system efficiency and lower utility bills.

Applications for Bubble Wrap Duct Insulation

Thanks to its durable and flexible design, R-8 bubble wrap insulation is suitable for a variety of uses. It’s ideal for both spiral and rectangular ducts, and can be installed in attics, basements, crawl spaces, or even beneath concrete slabs. Whether you're working in a residential or commercial space, this insulation is designed to perform in demanding environments.
