Flexible Duct

Shop insulated flexible HVAC duct for residential and light-commercial heating, air-conditioning and ventilation systems. Flexible duct provides a convenient way to route supply or return air through attics, crawl spaces and other areas where rigid ductwork may be difficult to install.

Choose from R-6 insulated flexible duct and R-8 insulated flexible duct in multiple diameters. Before ordering, verify the required duct diameter, insulation rating and length. The duct should be properly supported, extended to minimize compression and sharp bends, and securely connected and sealed to compatible collars or metal fittings.

Local energy and mechanical codes may specify a minimum insulation rating for ductwork installed in unconditioned spaces. Confirm local requirements and the HVAC equipment specifications before selecting R-6 or R-8 duct.
