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. 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 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 036 and 031 have increased insulation for superior thermal performance.

• 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/low operating cost
• Highly-resistant to mold growth
• Tough reinforced metallized polyester jacket tear and puncture-resistant/low maintenance
• Lightweight compact carton/bag reduces warehouse and jobsite handling cost
• Formaldehyde-free made with owens corning eco-touch insulation
