  • Reflectix® Big Bubble Duct Insulation (nominal thickness 1”) consists of two layers of highly reflective film (96% reflectivity) that are bonded to two tough layers of polyethylene. Two inner layers of insulating bubbles resist conductive heat flow while a center layer of polyethylene gives Reflectix® high reliability and strength. The product has a tape running the length of the roll for easy identification by code officials. The tape identifies the manufacturer and ASTM Testing: Reflectix® Duct Insulation • ASTM E84 • Class A / Class 1 • ASTM C411 Passed
  • Product Benefits (R-values) are dependent on installation technique.  The Reflectix® Big Bubble Duct Insulation provides an R-8.0 when installed with a 0.75” air gap between the duct and insulation, and R-6.0 when installed direct to the duct without a spacer.
