9 Inch x 25 Ft Insulated Flexible Duct Hose HVAC Triple Layer Aluminum Foil Air

Uninsulated ductwork running through unconditioned attics and crawlspaces leads to heavy temperature loss, higher energy bills, and messy condensation leaks. Designed to maintain steady airflow temperatures and reduce thermal transfer, this 9 inch x 25 ft insulated flexible duct hose delivers reliable performance for residential and commercial ventilation. Engineered with a triple-layer design featuring an inner aluminum core, thick glass wool insulation, and a reinforced outer vapor barrier, this flexible duct routes easily around joists and tight framing to keep your heating and cooling systems operating efficiently.

Triple-Layer Thermal Defense & Flexible Routing Performance

• Triple-Layer Protective Construction: Built with a durable inner aluminum foil core, a middle blanket of thickened glass wool insulation, and an outer reinforced glass fiber vapor jacket.
• Superior Thermal & Condensation Control: Retains heat during winter and blocks attic heat in summer while preventing moisture sweat from forming on outer surfaces.
• Acoustic Noise Dampening: Thick fiberglass insulation core absorbs blower drone and inline fan vibration, ensuring quiet airflow throughout living spaces.
• Kink-Resistant Wire Helix Core: Spring steel wire skeleton maintains full cylindrical airflow capacity while bending smoothly around rafters, trusses, and wall studs.
• Versatile HVAC & Exhaust Compatibility: Ideal for central air conditioning, furnace heating branches, inline exhaust fans, attic ventilation, and commercial air handlers.
• Generous 25-Foot Extended Span: Full 9-inch inner diameter by 25-foot operating length provides ample reach for long duct runs and custom routing.
