Insulated flexible duct helps reduce heat transfer and noise for smoother HVAC, dryer vent, and exhaust airflow. This 7.62 m (300 in) long, 127–130 mm (5.11 in) diameter duct combines high-loft glass fiber insulation with a reinforced three-layer jacket to support temperature control, dehumidification, and ventilation in home and grow tent setups. Flexible coil construction bends, compresses, or trims to fit tight runs with fewer installation headaches.

Built for real-world ventilation routes, this insulated ducting keeps airflow moving while helping stabilize temperatures and cut condensation risk in long runs. Use it for dryer vent hose replacements, HVAC supply/return extensions, exhaust and intake lines, greenhouse tents, and fresh air systems. The reinforced outer layer is designed to handle regular handling and repositioning, while the insulated core helps keep air closer to target temperature.
