Fig. 42 Gypsum wall construction- stuffing box and fire protection mastic

EIS 60

Position:
1 Fire damper
2 Gypsum plate
3 Mineral wool (type depending on the type of construction)
4 Mineral stone wool min. min. density 140 kg/m³
5 Fire protection mastic min. thickness 1 mm
6 Duct

Used materials - example:*
4 Promapyr, Rockwool Steprock HD, Hilti CFS-CT B 1S 140/50

5 Promastop - P, K, Hilti CFS-CT

* Fire resistant insulation and fire resistant board can be replaced by another approved fire sealing system

for damper installation with equivalent material properties.

The damper must be anchored to the fire wall construction!
Shown schemes of incorporation and damper are illustrative only!

Installation opening has to be

reinforced by profile (UW, CW).

Profil is fixed by screws

≥3,5 mm with corresponding

length. Distance between

screws ≤200 mm.
