Underground Preinsulated Duct System

Code Approval

The BlueDuct® is an underground plastic air duct and fitting system, designed specifically for underground or below slab forced air systems. The system meets all national codes for underground ductwork. The BlueDuct was specifically designed to address common shortfalls and issues such as leakage, water intrusion, mold, mildew, radon, and inadequate thermal efficiency, installing insulation in the field, corrosion, sustainability and seal testing.
