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. 28 and Fig. 29).
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
"5.6.6 Mounting a reducer" on page 36). The wall connection 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 two following examples show the mounting of wall penetrations. The
ceiling penetration is mounted in essentially the same way.

Wall penetration in solid wall

The mounting process described below allows achievement of a fire re-
sistance class I90, depending on the fire resistance length of the wall. For
I 120, see "5.6.6 Mounting a reducer" on page 36.
