The rFOIL BIG-8 reflective bubble duct insulation is specially designed to reduce radiant heat gain/loss in all residential duct applications. It helps control condensation by providing an airtight thermal break around ductwork. It increases system efficiency, lowers stress on HVAC equipment, and reduces energy usage and utility bills. The reflective bubble (nonfibrous) insulation achieves R-8 (with air space) or R-6 (without air space). According to the manufacturer, the thermal value is unaffected by moisture or humidity; won’t harbor mold, mildew, or other fungi; prevents exterior buildup of condensation; and no foam corner spaces are needed.
