Dryer Vent Hose, 4'' Insulated Flexible Duct

Features

• Efficient Insulation: Made with thick aluminum foil material and high-strength spiral steel wire, encased in a layer of fibreglass insulation, effectively reducing heat loss and improving thermal efficiency.
• High-Quality Insulation Cotton: Utilizing high-loft Owens Corning insulation cotton, it reduces heat conduction while absorbing noise generated during operation, enhancing user comfort.
• 3-Layer Tough: Constructed from durable aluminum plating and PET, reinforced with a fibreglass grid, achieving an R-6.0 flame resistance value, ensuring safety during operation and extending the product's lifespan.
• Flexible and Easy to Use: Can be bent, compressed, or cut as needed for installation without affecting the interior of the duct, reducing air resistance and improving installation adaptability.
• Variety of Applications: Primarily used for temperature control, dehumidification, and ventilation needs in various settings such as central air conditioning, fresh air systems, and greenhouse tents.
