• 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 - Tested and Listed to UL Environment's Standard UL 2824 Certified for Low Chemical Emissions - Tested and Certified to UL Environment's Standard UL 2818 Certified Thermal Performance (R-values) - UL Classified to Air Diffusion Council test program 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 EcoTouch Insulation

All thermal performance (R-Values) are certified by the Air Diffusion Council (ADC) and classified by UL LLC in accordance with ADC Flexible Duct Performance and Installation Standard using ASTM C-518, at installed wall thickness, on flat insulation only. 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.
