Wall penetration in dry/lightweight construction 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 “6.3.8 Mounting a wall/ceiling penetration” on page 62.
Note!
The distance from the wall to the next suspension points must not exceed
350 mm.

• Lay the ends of the duct on a mineral fibre plate

.
• When plugging the mineral wool

, it is advisable to use an im-
plement such as a stick and push as much as possible into the gap
above the ducts, in order to achieve as high a density as possible.
• Moisten the surface of the mineral wool and the mineral fibre plate
slightly with water and coat both sides with filler

with a thickness of
min. 2 mm.
