Flexible air duct Quietflex R6 #18

The R6 insulation helps reduce heat transfer and maintain conditioned-air temperature as air moves through the duct system. Its protective outer jacket helps shield the insulation and provides an effective vapor barrier when properly installed and sealed.

The Quietflex R6 4-inch insulated flexible air duct provides a practical and dependable solution for residential and light commercial HVAC air-distribution systems. Its flexible construction makes installation easier in attics, crawl spaces and confined areas where rigid ductwork may be difficult to route.
