Akustik+Sylomer® acoustic hangers provide an extraordinary performance on wooden structures.
ACOUSTIC ADVANTAGES
In order to show the acoustic advantages when using Akustik+Sylomer® acoustic hangers, the German IFT Rosenheim technological center has performed Impact and airborne noise tests using 2 different types of wooden structures.
- Wooden ceiling using sand as a filler: Reduction of impact noise 19dB, Gain of airborne isolation 18 dB.
- Wooden ceiling using mineral wool as a filler: Reduction of impact noise 14 dB, Gain of airborne isolation 6 dB.
In both kinds of ceilings a comparison has been done in order to determine the acoustic advantage that provides using Akustik+Sylomer® hangers.

Results:
Wooden ceiling filled with sand

INSTALLATION ADVANTAGES
There are several versions of the Akustik+Sylomer® acoustic hangers that suit specifically wooden structure ceilings:
ACOUSTIC ADVANTAGES GRANAB
In order to show the acoustic advantages when using Granab® in wooden floors, we include 2 acoustic tests where the improvements in impact and airborne noise can be clearly seen.
- Test realized in work (not Laboratory)
- AF CONSULT Laboratory test
In both tests, a comparison has been done in order to determine the acoustic advatages of Granab®.
