The Delta Duct FD5 – RN is the most robust standard insulated flexible duct in the range. It utilizes a reinforced metalized PET outer jacket and a heavy-duty inner core of double-layer ALU PET and clear polyester. This combination provides the highest level of mechanical resistance and thermal reflection, making it ideal for the most demanding HVAC environments.
