EIS 90
EIS 120 *****
Position:
1 Fire damper
2 Solid wall construction
3 Mineral stone wool min. density 140 kg/m³
4 Fire protection mastic min. thickness 1 mm
5 Cement lime plate min. thickness 15 mm
(min. density 870 kg/m³)
6 Stone wool bound with use of an organic resin
with crushed stone as a refrigerant, min. density
300 kg/m³ and min. thickness 60 mm
7 Profil U25x40x25
8 VRM****
9 Duct
** Stuffing box, fire protection mastic, cement lime plate and insulation materials can be replaced by
another approved fire sealing system for damper installation with equivalent material properties.
*** Depends on the distance of the flap from the construction, when the maximum distance from
the construct is not limited and according to EN 15882-2 must use the required number of
hinges according to EN 1366-1:2014.
**** Reinforcement fixing VRM see Fig. 81 Installation of profile U25x40x25 see Fig. 82
***** When using Rockwool Conlit Ductrock EIS 120, th. 60 mm, the overall fire resistance of the EIS 120
can be achieved.
T - thickness of the insulation (mm)
The duct at the point of penetration can be anchored to the fire wall construction!
Shown schemes of incorporation and damper are illustrative only!
Used materials - example:**
3 Promapyr, Rockwool Steprock HD,
Hilti CFS-CT B 1S 140/50
4 Promastop - P, K, Hilti CFS-CT
5 Promatect - H
6 Rockwool Conlit Ductrock EIS 90, th. 60 mm
Screws has to be fixed in wall/
ceiling construction.
(If it is needed use steel bracket).
