ATCO #070, #076, and #078 are UL 181, Class 1 Air Ducts and are manufactured with a tri-directional fiberglass scrim reinforced, grey polyester outer jacket. A double lamination of tough polyester which encapsulates a steel wire helix forms the air-tight inner core of the ATCO #070, #076, and #078. The double-layer core of each product is wrapped with a thick blanket of fiberglass insulation. The inner core of all three products is air tight and designed for low-to-medium operating pressures in HVAC systems.
