The following indications are given for the installation walls:
• metal profiles minimum width: 49 mm;
• metal profiles minimum thickness: 0,6 mm;
• vertical profiles placed with a maximum spacing of 625 mm be-
tween each other;
• vertical profile fixing with selfthreading screws or by clinching to
the bottom horizontal profile and insertion in the top horizontal
profile;
• profiles fixed using self-threading screws or by clinching on every
intersection.
• installation of a frame around the damper with base and height
where shown in the installation instructions;
• Filling made of rock wool with density up to 100 kg/m³ (optional);
• each side is made from two plasterboard layers 12,5 mm minu-
mum thick, unalinged to avoid alignment between the joints of
the layer above and below.
• the front plasterboards layers are fixed using long enough screws
to pass through the lower plasterboard and attach to the steel pro-
file underneath.

Gypsum blocks light walls
†
Gypsum blocks wall can be built with special solid gypsum blocks
with interlocking shaped edges as indicated in the supplier's instruc-
tions and according to the following characteristics:

formed slabs with interlocking shaped edges according to the fol-
lowing characteristics:
• minimum thickness 100 or 150 mm according to the resistance
class required;
