of the bare ceiling with one or two layers of Idikell . On the bottom side, a suspended ceiling decoupled with AmpaphonZ 600 and weighted down with Idikell improves the sound insulation considerably. Cavities [...] resistance.

With dry constructions weighted down with Idikell , sound insulation can be improved effectively at a low construction height and mass. Further im

Idikell is very thin and has a high surface weight. It is also flexible. Heavy foils [...] Additional mass will be the most effective if it is flexible. If, for example, one or two layers of Idikell are applied to a wood-based panel, it will not increase the bending stiffness by much. Number of
