The Vevor insulated flexible duct is designed for ventilation, heating, cooling, and exhaust applications that require thermal efficiency and flexible installation. It features a three-layer construction with aluminum foil, PET, fiberglass grid reinforcement, and Owens Corning insulation cotton to help reduce heat loss and absorb noise. The duct can be bent, compressed, or cut to suit different installation needs while maintaining airflow performance. With an R-6.0 thermal resistance value and included duct clamps, it is suited for HVAC systems, fresh air systems, and greenhouse tent ventilation.
