≥ 40 mm distance from fire damper to load-bearing
structural elements
Distance of ≥ 40 mm between two fire dampers
(80 mm for flange construction). When you install
two fire dampers next to each other into the same
opening, the concrete bed between the two fire
dampers must not exceed 225 mm.
1. Create the installation opening so that a sur-
rounding concrete cover of at least 50 mm is
ensured. Professionally connect the trimmers.
2. Create a partial concrete ceiling around the fire
damper, ≥ 150 mm, ≥ 150 mm thick.
Note:
Structural and fire resistance properties of the ceiling
construction, including the attachment to the con-
crete or any required reinforcement, have to be eval-
uated and ensured by others.
