R6. 0-12" SILVER FLEXIBLE DUCT 12"X25" (FLEX 12")

Product Description Insulated flexible ducts provide a flexible path for treated air to be moved through while reducing heat transfer to the surrounding space. They contain an insulating layer wrapped on both sides by a moisture and abrasion barrier. While they do not need the additional labor and insulating materials required to install rigid ducts, they are generally less durable. They are best suited for supply and return lines in low-to-medium pressure heating and air conditioning installations such as residential and commercial applications
