ADVANTAGES ON WOODEN STRUCTURES

12/3/2025

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.

INSTALLATION ADVANTAGES

There are several versions of the Akustik+Sylomer® acoustic hangers that suit specifically wooden structure ceilings:

Akustik 1+Sylomer®: The akustik 1 hanger is specifically suiting these kind of wooden structures. The installation with 2 fixation points is safe and easy.
Akustik Lateral+Sylomer®: The akustik Lateral hanger is specifically suiting the structures where no space is available and the acoustic hangers have to be fixed to the wooden beam.
Akustik lateral + Sylomer® acoustic hanger installation.

The installation with 2 fixation points is safe and easy.

Sprintec Lateral Acoustic Hangers: when low natural frequency is required this acoustic hanger can be used also.
It is specifically suiting the structures where no space is available and the acoustic hangers have to be fixed to the wooden beam. The installation with 2 fixation points is safe and easy. (insert installation image here).

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.
