• Air-tight inner core - energy efficient/no fiberglass erosion into air stream Encapsulated wire helix no unraveling when cut to length, quick installation Smooth inner core - low friction loss, lower operating cost Highly-resistant to mold growth Tough reinforced gray polyester jacket - tear and puncture-resistant/low maintenance Lightweight compact carton - reduces warehouse and jobsite handling cost Formaldehyde-free - made with Owens Corning EcoTouch insulation

Atco 070, 076 and 078 are UL 181, Class 1 air ducts and are manufactured with a tri-directional fiberglass scrim reinforced, gray 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. Atco 076 and 078 have increased insulation for superior thermal performance.
