Width and height of the shaft walls:
For the restricted dimensions, refer to the general building
authority test certificates (AbP). They depend on the size
of the framework profiles or the boundary fixations, and
the type and thickness of the cladding.

the operation side on the wall side with
cladding.
Cross-sections A-A on the right show
the installation of FK90K fire dampers
with the operation side on the profile side
of the wall without cladding. The profiles
of the circumferential frame must be com-
pletely filled to a height of at least 70 mm
with strips of wall cladding material, or
with construction boards made from calci-
um silicate,
≥
500 kg/m³. FK90K brackets
must be attached.
FK90K angle brackets can be shortened
by max. 34 mm in order to maintain the
minimum spacings.

When installing FK90K fire dampers
with the operation side on the unclad-
ded wall side (metal stud side), the pro-
files, which are circumferential at the
rear, must be filled with wall cladding
materials.

The minimum thicknesses W [mm] shown opposite
are required for installing the FK90K fire dampers:
vertical axis), the side profiles must be fitted with a 500 mm
excess length. If smaller dimensions are available, then
the side profiles must be butted up against the connection
profiles and secured as usual for this type of wall. Stud profiles
(supports) can replace side profiles.
• For FK90K fire dampers with dimensions within the span of
the framework, the bay rails should be connected to the stud
profiles according to standard practice in wall construction.
•
Walls without framework require laterally adjacent rigid walls
with angle profiles, onto which the freely spanned single-layer
or multi-layer wall cladding and extended bay rails of the
circumferential frame of the FK90K fire dampers should be
attached.
