74 VELUX

Metal sheets with pre-formed standing seam

Use ﬂashing EDW for installation of VELUX roof windows in roofs

with pre-formed steel sheets that are clicked together.

Note! Flashing EDE can be used for pre-formed zinc or aluminium

metal sheets, see page 76.

Install the window as shown in the installation instructions for the

window. Follow normal procedure for connection of underfelt and

insulation.

Position the metal sheets below the bottom frame, not closer to

the frame than the bottom installation batten. The sheet must con-

tinue at least 200 mm past the frame at the sides to make space

for ﬁtting the bottom ﬂashing section (1).

Fit the bottom ﬂashing section and shape the ﬂexible part of it

around the ribs of the metal sheets. Bend the bottom ﬂashing

section as shown in the installation instructions so that it presses

against the metal sheets (2).

Fit the ﬂashing around the window and cut the foam gasket to a

height of approx 25 mm. Flatten the rib of the top ﬂashing section

on both sides (3).

Position metal sheets around the window. The distances from the

metal sheets to top and side frames follow the standard instruc-

tions. Fix metal sheets around the window with screws with

tightening washers. Do not screw through the ﬂashing (4).
