Atco 030, 036 and 031 are UL 181, class 1 air ducts and are manufactured with a tri-directional fiberglass scrim reinforced, metallized polyester outer jacket. The inner core of all three products is airtight and designed for low to medium operating pressures in HVAC systems. Atco 036 and 031 have increased insulation for superior thermal performance. A double lamination of tough polyester which encapsulates a steel wire helix forms the airtight inner core of the Atco 030, 036 and 031. The double layer core of each product is wrapped in multiple thicknesses of fiberglass insulation. All three products are sheathed in a rugged and durable tri-directionally reinforced, metallized polyester jacket.
