8 Rockwool Wired Mat 105 th. 60 mm
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.
* 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 13366-1:2014.
The duct at the point of penetration can be
anchored to the fire wall construction!
