Creating a wall/ceiling penetration

With wall or ceiling penetrations, for the achievement of the fire resistance
class I30–I90, it is sufficient to plug the cavities around the duct with min-
eral wool and seal them with filler (see Fig. 50 and Fig. 51).
However, if I120 is to be achieved, then seal both sides of the penetration
with a wall connection fitting BSKM-WA 0711 or BSKM-WA 1025 (see
"6.3.8 Mounting a wall/ceiling penetration" on page 62). The wall con-
nection fitting is only available for BSKM 0711 and BSKM 1025.
The wall penetration can be created in a solid wall or a dry construction
wall (lightweight construction wall). When the wall connection fitting is
used, the ducts must run to the wall or ceiling at a 90° angle.
If there is a fire, to prevent heat transfer within the wall inside a duct to the
connection duct, the wall may not be penetrated with a single duct piece.
Instead, the ducts must be mounted separately within the wall with a gap
width of 5‒10 mm.
The following two examples show the mounting of a wall penetration. The
ceiling penetration is mounted in essentially the same way.
