Features & Benefits:
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 air-tight and designed for low-to-medium operating pressures in
HVAC systems. ATCO #036 and 031 have increased insulation for superior thermal performance.
Construction:
A double lamination of tough polyester which encapsulates a steel wire helix forms the air-tight 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.
