The BlueDuct® Underground Duct

AQC Industries is a leading manufacturer and innovator of The BlueDuct® underground duct systems for heating, ventilation and cooling (HVAC). The BlueDuct® is the only proven, direct-burial underground duct system made from ultra-durable, advanced HDPE (high-density polyethylene). There is no need for field insulation, field vapor barrier, or field concrete encasement (eliminating the need for two separate concrete pours). Simply “direct bury” the BlueDuct® onto the foam trench blocks, and backfill with pea gravel or dry silica sand.

The BlueDuct® Underground Duct products are engineered to protect against corrosion, mold and mildew, radon, rust and air leaks. The BlueDuct® systems have been installed in thousands of buildings, for over a decade, with trouble-free, long-term performance.
