Federal Court of Justice DIN 4109

The Federal Court of Justice asserted that the DIN 4109 has partial lost his contractual meaning of the sound insulation in the house building. Among other things the minimum requirements are not consistent with the technical norms. Architects, companies and specialised retailer have to consider legal sound insulation demands more sensitive to avoid later warranty claims. On the other side builder-owners have considerably higher rights to adequate sound insulation.
