AQC Introduces QDuct® Outdoor Preinsulated Duct System

Exterior duct system constructed to withstand harsh weather conditions

SHOREVIEW, Minn.—AQC Industries introduces QDuct® Outdoor Preinsulated Duct System, which is engineered for exterior and rooftop applications. Constructed to withstand harsh weather conditions in all climates, this rugged outdoor air-duct system saves energy, space and labor.
QDuct® Install
QDuct® is custom fabricated using two layers of rigid UL 181 Pal phenolic core material, faced on both sides with coated aluminum and an exterior multilayered laminate jacketing material. Self-insulated, this outdoor duct requires no additional weatherproofing or insulation and eliminates the need for an insulation subcontractor. QDuct® sections are delivered preassembled to the jobsite, ready for installation by a certified contractor. The product installs easily in a fraction of the time of traditional duct.

“Exterior insulated sheet metal air ducts are susceptible to air and water leaks. As a result, more energy is needed to heat and cool a building and indoor air quality can be compromised,” says Jim Lubratt, vice president of AQC Industries. “Self-insulated with an interlocking air- and water-tight design, QDuct® provides optimum indoor air quality while significantly reducing energy consumption and operating costs.”
QDuct® is made of PalDuct™ phenolic core panels which meets UL 181, ASTM E84 flame and smoke standards. The interior and exterior layers resist mold, mildew, UV and extreme weather conditions. QDuct® does not emit volatile organic compounds (VOCs) or toxic gases and contains no microfibers, chlorofluorocarbons (CFC) or hydrochlorofluorocarbons (HCF).

AQC Industries provides engineering and CAD services to meet specific application requirements. QDuct® is sold through a nationwide network of knowledgeable representatives and is manufactured using environmentally friendly practices. Virtually maintenance free, the product is lightweight and durable for quick and easy installation. Backed by an industry-leading warranty, QDuct® can contribute to LEED® points.
