Plastering the installation kit on the outside
► Insert the protective sleeves (item 1
in Fig. 25 and Fig. 26). They should
extend beyond the solid wall so that
they will end flush with the subse-

sleeves provide the bonding surface
for the external plaster.
NOTICE
► Prepare the substrate suitably
before plastering.
► Apply the plaster scrim (item 2 in
Fig. 25 and Fig. 26) to the outside of
the wall box, to the masonry and to
the facade insulation.
NOTICE
Applying plaster scrim will minimise
subsequent cracking of the plaster.
► Plaster the external wall. The plaster
forms the windtight layer on the
external wall.
