2. The soffit element must always be overinsulated. It is not suitable for insulation thicknesses ≤ 100 mm and must not be
installed there.
3. Horizontal distance from core drilling hole to soffit (ready-mix plaster): min. 220 mm to max. 500 mm (see Fig. 6)
4. Vertical distance from core drilling hole to window lintel: min. 300 mm

The length of the wall installation sleeve com-
prises the thickness of the uncovered wall with
internal ready-mix plaster and the immersion
depth (
) in the soffit channel (see Fig. 4 & 5).
ù
m NOTE: The length of the wall installation

Distance from core drilling hole (centre)
ä
to the end of the soffit channel
Max.: 480 mm
Min.: 200 mm
The shortenable length of the channel must be
selected depending on the distance between
the core drilling hole (centre) to the ready-mix
plaster in the window soffit. This distance
minus the height of the shortened plaster fra-
me (
ë
) provides the length of the shortenable
area

Height of the plaster frame
Max.: 35 mm
Min.: 15 mm
The height of the plaster frame bridges the dis-
tance between the soffit channel and the wall
grille. The height must be selected depending
on the thickness of the window soffit insulation
and the ready-mix plaster. The plaster frame
allows for tolerance compensation.
A minimum height of 20 mm is recommended
for the plaster frame.
