■
The fire damper can be integrated into a solid wall
construction made e.g. of normal concrete/masonry,
porous concrete with minimum thickness 100 mm or into
solid ceiling construction made e.g. of normal concrete
with minimum thickness 150 mm.

The fire damper can be integrated into a gypsum wall
