The Fantech FIDT6 Fiberglass Insulated Silver Flex Duct ensures smooth operation while reducing heat transfer for proper HVAC system and bathroom fan ducting. It features energy efficiency with a low-friction design and minimized air leakage.

• Reduced Costs: With overall thermal performance improved by adding this 6-inch flexible duct, you can expect lower energy costs.
• Core: An air-tight inner core keeps the air flowing in the direction it should, with reduced leakage.
• Material: A puncture and tear metalized polyester jacket protects the outside.
• Fiberglass: This flexible ductwork has R4.2 fiberglass insulation.
