Used materials - example:***
4 Rockwool Wired Mat 105 th. 60 mm
** 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 ceiling construction!
