The flexible core allows for routing through tight spaces, framing cavities, and attic runs where rigid ductwork is impractical. The R6 insulation rating provides thermal resistance suitable for unconditioned spaces such as attics and crawlspaces. The acoustical lining reduces airborne noise transmission between the air handler and supply registers, making it well suited for bedroom and living area applications. This duct ships in a 25-foot length and measures 6 inches in diameter.\u003c\/p\u003e\u003cp\u003eThis flexible duct is used in forced-air heating and cooling systems to connect branch runs from the plenum or trunk line to supply boots and registers. The 6-inch diameter is a common size for individual room supply runs in residential construction and retrofit work.
