®
Duro-Last Duro-Flash II may be used as a
termination under existing metal counterflashing. It is
fabricated from 3 inch wide vinyl coated metal and a
12-inch (152 mm) wide skirt. The skirt is made of
Duro-Last specially formulated roofing membrane,
which is a proprietary thermoplastic formulation,
available in white, tan, gray and dark gray colors.

Duro-Flash II is available in 10 ft. (3 m) lengths. The
skirt extends past the vinyl coated metal 3 inches
(76 mm) on each end to allow adjacent sections to
be heat welded (hot-air) together.

INSTALLATION:
1. Duro-Flash II shall be slid under the existing
metal counterflashing 1 inch (25 mm), minimum
(this is the width of the factory weld).
2. The skirt shall be held up to allow Duro-Last
fasteners to be placed 6 inches (152 mm) on
center, maximum, through the metal into the wall
substrate.

3. Heat weld (hot-air) the skirt to the Duro-Last
membrane already installed below the metal.
4. Refer to detail drawing 6142.
