Bostome 4-Inch Insulated Flexible Dryer Vent Duct 25FT R6.0

Before: Your laundry room feels like an icebox, the dryer works overtime, and you can hear every motor rattle through the wall. Cheap foil Dryer Vent tubes sag, leak heat, and let cold drafts sneak back in—driving up energy bills and wasting time.

After: You toss in a load, close the door, and feel warm, quiet comfort. The heater cycles less, clothes dry faster, and the utility bill drops—all without extra tools or HVAC calls.

Bridge: Make the switch with Bostome’s Insulated Flexible Duct 25ft. This 4-inch R-6.0 powerhouse sandwiches Owens Corning fiberglass between rugged aluminum and PET layers, locking in heat and muting motor hum. A steel-wire helix bends around joists or crawlspace corners without kinking and trims with scissors for a custom fit. Whether you’re venting a dryer, greenhouse fan, or wine-cellar HVAC, the built-in insulation keeps target temps steady and code-compliant.

• Triple-layer core stops heat bleed and flame spread
