Sound insulation of an apartment wall

The Sch. family, Cologne, Germany, reports:

We live in a multiple-family house built in 1920. The individual apartments are separated by ordinary, relatively thin walls that do not block off noises and voices, for instance people talking loudly or children shouting and crying. To remedy this situation, we decided to cover the partition walls with a sound insulation layer as part of a general refurbishment of our house.

The soniflex team recommended the construction of so-called curtain walling in front of the partition walls to block off the voices and other air-borne noises from the neighboring apartment. For such a curtain wall, a framework of 30 to 50 mm thick wooden slats is fixed to the wall, preferably on elastic spacers to ensure acoustic decoupling. Then soni PROTECT R sound insulation panels are mounted in the spaces between the slats. As a last step, plaster wallboards or particle boards are fixed on the slat framework with screws. An even better sound absorption effect is achieved when the sound protection material, here soni PROTECT R, is not fixed directly on the wall but to the wooden slats (30 mm) before mounting the wallboards.

For optimum overall effectiveness, the wallboards should be decoupled from the side walls, the ceiling and the floor by filling the gaps with acrylic putty.

Handling and cutting the soni PROTECT R sound proofing panels was totally easy and we had no trouble installing the curtain walling. For this we could rely on the detailed and sound advice provided by the very knowledgeable soniflex team. The result was just what we had hoped for: Now the sounds and noises from the neighboring apartment are virtually imperceptible on our side of the wall.

soni PROTECT R is a highly effective sound absorption material and offers higher sound insulation values than melamine foam alone. Used as sound absorber in the hollow space behind a curtain wall, soni PROTECT R achieves a considerable reduction of any resonances that might occur and thus improves the overall sound protection effect.

Insulation of the bedroom against neighbourhood noise

The W. family, Berlin, Germany, reports:

After having moved in our end-terrace house we realised that habitation noise (such as moving noises and loud music) of our neighbours were clearly perceptible. These noises were particularly disturbing in our bedroom. We therefore decided to insulate the adjacent wall to our neighbours. After having installed the self-adhesive sheets soni COMPOSITE on the concrete wall, the air-borne noises (voices, loud music) were no longer perceptible. The footfall sound noises were considerably reduced.
