The core layer has a density increasing in the direction of the two outer layers and consists of a plastics material having preponderantly open cells.EDER B
Fastening elements, for example wooden ribs 3, are embedded in the elastic layer and serve as the place of attachment for the surface layer. EKSTRAND, CARL-GUNNAR
The invention relates to a sound-damping element (1), in the outer layers (3, 5) of which U-profiles (6-11) are inserted. The U-profiles (6-11), preferably made of steel, increase the sound-damping value of the element from 39 dB to 44 dB. Gluing the U-profiles (6-11) into...
