Insulated dryer vent hose helps keep exhaust air hotter for steadier airflow and reduced heat loss in long runs. This 7.62 m (300") flexible duct combines aluminum foil, PET, spiral steel wire, and fiberglass insulation to support HVAC heating/cooling ventilation, dehumidification, and grow tent air exchange. Bend, compress, or trim to fit tight spaces while maintaining a smooth interior to help limit air resistance.

Built for demanding ventilation paths, this heavy-duty insulated flexible duct uses a reinforced, triple-layer construction to handle frequent adjustments without sacrificing shape. The thick insulated wall helps maintain air temperature through attics, basements, or long duct runs, while the smooth interior supports consistent airflow. Ideal for central air systems, fresh air setups, dehumidification, greenhouse tents, and general exhaust.
