QDuct® Installation | Insulated Outdoor Duct System

Outdoor Duct Made Easy.
Withstands Harsh Weather Conditions.

Engineered for exterior use, Q Duct® Outdoor Preinsulated Duct System is constructed to withstand harsh weather conditions in all climates. Q Duct 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. Requiring no additional insulation or weatherproofing, Q Duct sections are delivered pre-assembled to the job site ready for installation by a trained contractor. The product’s unique design easily installs in a fraction of the time of traditional insulated sheet metal duct, saving money and labor.

Q Duct’s patent-pending support mounting system utilizes external channel strut connected to the internal bracing structure of the Q Duct system. This allows for quick and easy mounting of ducts to support rails for both horizontal and vertical mounting orientations; saving contractors time and money.


Many traditional outdoor duct systems suffer from water ponding on top of the ducts resulting in mold, mildew, and rust. These problems can eventually make their way into the duct system and diminish the air quality of the system. Q Duct’s patent-pending sloped roof design helps to ensure water is quickly shed from the duct surface.

Unlike other traditional systems on the market, Q Duct’s quadruple interlocking system, Q Lok®, features redundant seals to help ensure industry-leading low leakage & maximum energy efficiency. This additional feature is easy and fast to install, saving both time and money during the building process.
