Plastering the internal wall
NOTE
►
Prepare the substrate suitably before
plastering.
►
Before plastering, close off both ends of
the ventilation pipes with adhesive tape
(item 1 in Fig. 18) or another suitable
material.
►
Trim the expanding foam (item 2 in
Fig. 18) flush with the unplastered wall.
►
Plaster the cable ducts.
►
Plaster the internal wall as far as the
ventilation pipes. The plaster forms the
airtight layer on the internal wall. The
expanding foam does not act as an airtight layer.
NOTE
When the ventilation unit is subsequently surface-mounted, the internal wall is already plastered.
►
In this case, remove the expanding foam as far as the unplastered wall and then plaster
the gap around the ventilation pipe. The plaster forms the airtight layer on the internal wall.
The expanding foam does not act as an airtight layer.
