Hart Cooley 27830 F2181225 Flexible Air Duct R-8.0 Insulation 12 Inches X 25 Ft Silver Residential

Product Description

The Hart Cooley 27830, also known by model number F2181225, is a 12-inch diameter by 25-foot silver flexible air duct designed for residential HVAC installations. This insulated flex duct features R-8.0 thermal insulation, making it one of the higher-performing insulation ratings available in residential flexible ductwork. HVAC technicians and contractors use this type of flex duct to connect supply air plenums and branch takeoffs to diffusers, registers, and grilles throughout a home. The inner core carries conditioned air from the air handler or furnace, while the thick R-8.0 insulation jacket reduces heat gain or heat loss as that air travels through unconditioned spaces such as attics, crawlspaces, and basements. Reducing thermal loss in these zones directly improves system efficiency and comfort in living spaces. The silver outer jacket is durable and resistant to tearing during installation. This duct is UL Listed, which confirms it meets industry fire and safety standards required by most local building codes. It also carries GREENGUARD Level 4 certification, indicating low chemical emissions and making it suitable for use in residential environments where indoor air quality is a priority. The 25-foot length provides enough run for most standard branch duct installations without requiring splices. At 12 inches in diameter, this duct is sized for higher-volume supply branches or trunk-to-register connections in larger rooms or open floor plans. Flexible duct is preferred by many installers for its ease of routing around structural obstructions, its compatibility with standard sheet metal fittings and clamps, and its ability to absorb vibration and reduce noise transmission from the air handler. This product ships boxed and is ready for immediate installation on residential new construction or retrofit projects.
