Integration – more windows

In general

FLASHINGS

In general, a single ﬂashing consists of a

bottom ﬂashing section (1), side sections

(2) and a top ﬂashing section (3).

Basically, the same components are used

when combining windows together. They

are, however, supplemented with compo-

nents that ensure drainage between the

windows.

VELUX uses two drainage principles:

LOW-LYING MIDDLE GUTTERS

Flashings with low-lying middle gutters

drain o the water from the roof surface

above the window down both sides of each

individual window and the centre channel

between.

This principle makes it possible to combine

an unlimited number of windows in the roof

surface.

The principle is used for the combi ﬂashing

system.

HIGH-LYING MIDDLE GUTTERS

Flashings with high-lying middle gutters

drain o the water from the roof surface

above the windows down the outer sides

only of the window combination.

This principle makes it possible to install the

windows closer to each other. This drainage

principle is used eg for twin ﬂashing EB-.

The total width of a combination with high-

lying middle gutters must not, however,

exceed 2780 mm.
