Check out this video to see a flame test comparing the standard dryer vent “slinky” hose you buy in the store (and is highly flammable) with an aluminum, rigid vent (difficult to work with, but less flammable) and this DryerFlex® transition duct (which has the ease-of-use of a slinky-type duct, but is even more flame-resistant than rigid aluminum).
