Dundas Jafine Insulated Flexible Duct Black Jacket - Fiber Insulation - 4 In x 25 Ft — Residential Use, Standard Application

Product Description The Dundas Jafine 4 in x 25 ft flexible insulated duct is designed for efficient air movement in residential and commercial ventilation systems. This heavy duty flexible ducting features a fiber insulation layer with an R6 value to help reduce heat and cool loss, making it ideal for heating, air conditioning, intake, and exhaust applications. The core is constructed from a 2-ply polyester laminate with a corrosion-resistant zinc-coated wire helix, providing durability and flexibility for easy installation, even in tight spaces where elbows are difficult to use. The black polyethylene vapor barrier is fire retardant, adding an extra layer of safety. This 4 inch insulated ducting is UL and cUL 181 listed as a class 1 air duct, ensuring it meets safety standards. The flexible insulated duct can often replace traditional galvanized pipe, but always check local building codes before installation.
