rFOIL BIG-8 Duct Insulation provides an R-8.0 insulation value that helps control radiant heat gain/loss while limiting interior condensation in HVAC applications. Installed properly, the BIG-8 provides an air-tight thermal break around the duct which helps increase system efficiency, lowers stress on HVAC equipment and helps reduce energy usage and utility bills.
Installers like using the BIG-8 Duct insulation over the standard FSK type wrap due to the time savings in cutting, taping and installing the product.
