Double Bubble Foil Insulation reflects radiant heat and helps prevent heat gain and loss, improving overall energy efficiency and promoting consistent indoor temperatures throughout the year. Constructed with two layers of polyethylene bubbles sandwiched between two metalized foil surfaces, this insulation also helps prevent the formation of frost and condensation in metal buildings, pole barns, crawl spaces, and similar structures.
When properly sealed, it also acts as a vapor barrier—blocking moisture, methane, radon, and other unwanted intrusions. Rated ASTM E84 Class 1 / Class A for fire resistance, it’s a safe and effective choice for a wide range of applications.
This lightweight, user-friendly insulation is available in both Foil/Foil and White/Foil finishes, offering either maximum reflectivity or a cleaner interior-facing appearance, depending on your project needs.
