The Vevor insulated flexible duct is designed for dryer venting, HVAC, heating, cooling, ventilation, and exhaust applications. Its three-layer construction combines aluminum foil, PET, and a fiberglass grid for durability and dependable performance. High-loft insulation helps reduce heat transfer while also absorbing operating noise. The flexible design can be bent, compressed, or cut to suit different installation needs. Two duct clamps are included for a more convenient setup.
