Constituents of the Flashing

The flashing consists of four basic elements (a single, lower element joining two windows, two side and one top single element for both windows). The lower part of the flashing completed with a flexible apron has a plastic mass glued to the underside thus allowing the flashing to adhere to the roof covering for a neat fit.
The EZV DUO flashing is factory equipped with sponge seals providing protection against wind blown dust, leaves, rain and snow. The flashing is also equipped with a weep flap to allow condensation to be drained away from the initial roofing layer and window.
