Today's Safest and Most Efficient Clothes Dryer Transition Duct
For years, two types of 4" clothes dryer transition ducts have been available: "slinky" foil and semi-rigid aluminum. Each features unique benefits as well as disadvantages for both installers and homeowners.
"Slinky" foil is very easy to work and can fit in tight spaces because of its flexibility. However, its flammable Mylar coating and abrasive, airflow-disrupting 3.25" inner diameter make it dangerous and inefficient.
Semi-rigid aluminum sometimes has an good flame rating and a full 4" opening to maximize airflow efficiency. Because of the rigidity of this material, semi-rigid ducts are harder to bend in tight areas and the material deforms, or it crushes easily when pressure is applied.
The Best of All Worlds
With common transition ducts having some pros and cons, it was time to create a product that featured the best of both worlds. Today, DryerFlex is the only UL-2158A transition duct available that's as flexible as foil yet features the same airflow efficiency and fire safety as semi-rigid aluminum.
DryerFlex retains a full 4" opening whether compressed or stretched which helps ensure continuous airflow without creating lint catching points. Because of its tight turns, using DryerFlex can often eliminate the need for a hard 90 degree elbow making your overall duct run shorter and more efficient.
