Solid walls
Solid walls or compartment walls made of, for
example, concrete, aerated concrete, masonry, or
solid gypsum wallboards according to EN 12859
(without open spaces), gross density
≥
350 kg/m³.
Wall thickness W
≥
100 mm, solid gypsum wall-
boards W
≥
80 mm.
Provide each installation opening and core drilled
holes according to the local and structural conditions
and with regard to the dimensions of the fire
damper.

Lightweight partition walls with metal support struc-
ture
Lightweight partition walls, safety partition walls or
walls to provide radiation protection, with metal sup-
port structure or steel support structure (box sec-
tions), with European classification to EN 13501-2 or
equivalent national classification.
Cladding on both sides made of gypsum bonded or
cement bonded panel materials, fibre-reinforced
gypsum or fire-rated calcium silicate boards.
Wall thickness W
≥
94 mm, for compartment walls or
safety partition walls W
≥
100 mm.
Distance between metal support structures
≤
625 mm; distance between metal support struc-
tures in compartment walls
≤
312.5 mm.
Compartment walls and safety partition walls may
be provided with sheet steel inserts and may require
less space between the metal studs.
Create an installation opening with trimmers (studs
and noggings).
If necessary, provide trim panels and screw-fix them
to the support structure
Additional layers of cladding (if stated in the usability
certificate for the wall) or double stud constructions
are approved.
Connect the metal sections near the installation
opening according to the installation details in this
manual.
If reinforcing boards are required, they must be
screwed to the metal support structure at intervals of
approx. 100 mm.
Installation only permitted in non-load-bearing walls
(load-bearing wall constructions on request).
The structural properties of the wall must be
ensured by others and any necessary compensation
measures, especially with large installation open-
ings, must be checked and taken into account by
others.
