duct trough wall. Distance between
suspensions is max. 800 mm
(thickness of threaded rod for
suspension should be M12 or more.
Damper blade must be closed during
installation!
2. Install fire damper and secure it to
ventilation duct. Fill space between duct
and wall with mineral wool (Isover U protect).
Additionally, paint wool with Isover BSF in
thickness of 1 mm.
3. Close installation with L profiles
30x30x3 mm. Additionally fix profiles
to duct with self-tapping screws, and
screw them to wall with 4,5x50 screws
with 200 mm distance between them.
On connection wool-wall apply glue
Isover BSK in thickness of 2 mm.
Repeat the same procedure on the
